+
+<p class=MsoBodyText>The internal Forward Lock file format is used for encrypting
+inherently unencrypted OMA DRM version 1 Forward Lock and Combined Delivery
+files so they can be securely stored on externally accessible file system partitions
+such as memory stick.</p>
+
+<p class=MsoBodyText>Our general strategy is to convert such <i>OMA DRM Message</i>
+(‘.dm’) files to internal Forward Lock (‘.fl’) files as soon as they are
+downloaded or otherwise transferred to the phone, and not actually provide any
+decoders for ‘.dm’ files.</p>
+

+</span>Overview</a></h1>
+
+<p class=MsoBodyText>The <i>Forward Lock Converter</i> converts OMA DRM Message
+files to the internal file format. The <i>Forward Lock Decoder</i> provides a
+POSIX-level API for transparent reading and seeking through such a converted
+file as if it were unencrypted. The API also includes functions for checking a
+file’s integrity and getting the MIME type of its embedded content.</p>
+
+<p class=MsoBodyText style='margin-bottom:24.0pt'>The converter and decoder are
+built into two separate libraries, which share common code for random number
+generation and key encryption in a third library. For test purposes there is
+also a unit test application. See Figure 1.</p>

+
+<p class=MsoBodyText>This section describes all the use cases for the converter
+and decoder. It shows the sequence of API calls that should be used to solve
+these use cases.</p>
+
+<h2><a name="_Toc276471425">3.1<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;
+</span>Converter</a></h2>
+
+<p class=MsoBodyText>Through the converter API, conversion can be performed in one
+of two ways:</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span><i>Push-mode
+conversion</i> is when the client progressively feeds data to the converter as
+it arrives. This is appropriate when data arrives gradually in chunks, with
+idle time in between. Consequently, push mode is used for converting files
+being downloaded through HTTP. See section 3.1.1.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span><i>Pull-mode
+conversion</i> is when the converter drives the process and consumes data from
+the client as it needs it. This is appropriate when the entire file to be
+converted is readily available. Hence, pull mode is used by the unit test application.
+See section 3.1.2.</p>
+
+<p class=MsoBodyText>Internally, pull-mode conversion is implemented in terms
+of the API for push-mode conversion.</p>
+
+<h3><a name="_Toc276471426"></a><a name="_Ref263085478">3.1.1<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp; </span>Convert Data
+(Push-Mode Conversion)</a></h3>
+
+<p class=MsoBodyText>Push-mode conversion is performed as follows (see also Figure 2):</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span

+initializes the output parameter and returns a <i>session ID</i> to be used in
+subsequent calls to the API. The output parameter is a union of return values
+whose correct use at any given moment is determined by the API function last
+called.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span><span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockConv_ConvertData</span>
+is called repeatedly until no more input data remains. Each call converts the
+maximum amount of data possible and writes it to the output buffer. The client then
+writes this data to file.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>3.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span><span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockConv_CloseSession</span>
+cleans up the session and deallocates the output buffer. If all has gone well, a
+two-part cryptographic signature of the output file is calculated. The client
+must go back and rewrite part of the file header with this updated signature
+information.</p>
+
+<p class=MsoBodyText>Every time a file is being converted, the converter calls <span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_GetRandomNumber</span>
+to generate a new, unique session key. No two converted files look alike, even
+if the original files are the same.</p>
+
+<p class=MsoBodyText><b>Note:</b> The random bytes cannot come from any bare-minimum
+implementation of the C-library <span style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>rand</span>
+function—they must be cryptographically secure. Otherwise, security will be
+compromised.</p>
+
+<p class=MsoBodyText>The session key is encrypted and stored within the
+converted file. Key encryption is performed using <span style='font-size:10.0pt;
+font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_GetEncryptedKeyLength</span> and <span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_EncryptKey</span>.
+These two functions, together with the corresponding decryption function (<span
+style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>FwdLockGlue_DecryptKey</span>),
+are the integration points where an OEM manufacturer may implement their own
+key-encryption scheme.</p>
+
+<p class=MsoBodyText><b>Note:</b> The key-encryption key must be unique to each
+device; this is what makes the files forward lock–protected. Ideally, it should
+be derived from secret hardware parameters, but at the very least it should be
+persistent from one master reset to the next.</p>

+since the source code is openly available). This key must be kept secret from

+
+<p class=MsoBodyText>All subsequent operations on a file first require it to be
+opened. Opening a file returns a <i>file descriptor</i>—a handle to be used in

+
+<p class=MsoBodyText>If the filename is known, an internal Forward Lock file

+
+<p class=MsoBodyText>Internally, <span style='font-size:10.0pt;font-family:

+
+<p class=MsoBodyText>As of now, neither Combined Delivery nor usage
+restrictions (including SIM binding) are supported. These fields are reserved
+for future use.</p>
+
+<h2><a name="_Toc276471433">4.1<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;
+</span>Key Derivation</a></h2>
+
+<p class=MsoBodyText>The session key consists of sixteen bytes fetched from a
+cryptographically secure random number generator. From the session key, two
+separate keys are derived: one used for encryption, the other for signing.</p>
+
+<p class=MsoBodyText>The encryption key is the output from encrypting the
+16-byte all-zero input block {0, 0, …, 0} using 128-bit AES with the random session
+key as the key. The signing key is the output from encrypting the 16-byte input
+block {1, 0, …, 0} the same way. The keys so derived will be cryptographically
+independent from each other.</p>
+
+<p class=MsoBodyText>The session key is encrypted using a hardware-dependent
+key-encryption key unique to each device. The encrypted session key is stored
+inside the file, and its first sixteen bytes are also used as the <i>nonce</i>
+for the CTR-mode encryption of the content data.</p>
+
+<h2><a name="_Toc276471434">4.2<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;
+</span>Calculation of the Counters</a></h2>
+
+<p class=MsoBodyText>Using CTR (“counter”) mode, a block cipher such as AES can
+be turned into a stream cipher. The process of encryption and decryption is
+well defined in [1], except for the specifics of the calculation of the
+counters. For the internal Forward Lock file format, the counters are
+calculated as follows:</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span>The
+nonce is interpreted as a 128-bit unsigned integer in little-endian format.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span>The
+zero-based block sequence number (also a little-endian unsigned integer) is
+added modulo 2<sup>128</sup> to the nonce to produce the counter for a given
+block.</p>
+
+<h1><a name="_Toc276471435">5<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+</span>Unit Test Cases</a></h1>
+
+<p class=MsoBodyText>Unit test cases for the converter and decoder come in two
+varieties:</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>1.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span><i>Black-box</i>
+test cases aim to verify that you get sensible results from malformed or
+“tricky” input data.</p>
+
+<p class=MsoBodyText style='margin-left:36.0pt;text-indent:-18.0pt'>2.<span
+style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span><i>White-box</i>
+test cases aim to maximize code coverage using knowledge of code internals.</p>
+
+<p class=MsoBodyText>The black-box test cases are dependent on a specifically
+designed set of input files found in the <span style='font-size:10.0pt;
+font-family:"Lucida Console","DejaVu Sans Mono"'>forward-lock/internal-format/test/res</span>
+directory in the repository. For ‘tests’ variants of the software, these input
+files will be automatically installed in the file system image during build.</p>
+
+<p class=MsoBodyText>Run the test cases from the ADB shell command line as
+follows:</p>
+
+<p class=MsoNormal style='margin-top:0cm;margin-right:0cm;margin-bottom:6.0pt;
+margin-left:21.55pt'><span style='font-size:10.0pt;font-family:"Lucida Console","DejaVu Sans Mono"'>#
+gtest_fwdlock</span></p>
+
+<p class=MsoBodyText>If all black-box but no white-box test cases fail, the
+input files probably can’t be found in the working directory.</p>

+ * The purpose of ICameraRecordingProxy and ICameraRecordingProxyListener is to
+ * allow applications using the camera during recording.
+ *
+ * Camera service allows only one client at a time. Since camcorder application
+ * needs to own the camera to do things like zoom, the media recorder cannot
+ * access the camera directly during recording. So ICameraRecordingProxy is a
+ * proxy of ICamera, which allows the media recorder to start/stop the recording
+ * and release recording frames. ICameraRecordingProxyListener is an interface
+ * that allows the recorder to receive video frames during recording.
+ *
+ * ICameraRecordingProxy
+ *   startRecording()
+ *   stopRecording()
+ *   releaseRecordingFrame()
+ *
+ * ICameraRecordingProxyListener
+ *   dataCallbackTimestamp()
+
+ * The camcorder app opens the camera and starts the preview. The app passes
+ * ICamera and ICameraRecordingProxy to the media recorder by
+ * MediaRecorder::setCamera(). The recorder uses ICamera to setup the camera in
+ * MediaRecorder::start(). After setup, the recorder disconnects from camera
+ * service. The recorder calls ICameraRecordingProxy::startRecording() and
+ * passes a ICameraRecordingProxyListener to the app. The app connects back to
+ * camera service and starts the recording. The app owns the camera and can do
+ * things like zoom. The media recorder receives the video frames from the
+ * listener and releases them by ICameraRecordingProxy::releaseRecordingFrame.
+ * The recorder calls ICameraRecordingProxy::stopRecording() to stop the
+ * recording.
+ *
+ * The call sequences are as follows:
+ * 1. The app: Camera.unlock().
+ * 2. The app: MediaRecorder.setCamera().
+ * 3. Start recording
+ *    (1) The app: MediaRecorder.start().
+ *    (2) The recorder: ICamera.unlock() and ICamera.disconnect().
+ *    (3) The recorder: ICameraRecordingProxy.startRecording().
+ *    (4) The app: ICamera.reconnect().
+ *    (5) The app: ICamera.startRecording().
+ * 4. During recording
+ *    (1) The recorder: receive frames from ICameraRecordingProxyListener.dataCallbackTimestamp()
+ *    (2) The recorder: release frames by ICameraRecordingProxy.releaseRecordingFrame().
+ * 5. Stop recording
+ *    (1) The app: MediaRecorder.stop()
+ *    (2) The recorder: ICameraRecordingProxy.stopRecording().
+ *    (3) The app: ICamera.stopRecording().

+// auto disabled mode, or that there is at least one other registered listener
+// active in the system.  The CCHelper makes this a little easier by sharing a

+     * effect engine owner, the control will be transfered to the new application. Otherwise
+     * control will remain to the previous application. In this case, the new application will be
+     * notified of changes in effect engine state or control ownership by the effect callback.
+     * After creating the AudioEffect, the application must call the initCheck() method and
+     * check the creation status before trying to control the effect engine (see initCheck()).

+ * quality audio content. However, to protect privacy of certain audio data (e.g voice mail) the use
+ * of the visualizer requires the permission android.permission.RECORD_AUDIO.
+ * The audio session ID passed to the constructor indicates which audio content should be
+ * visualized:
+ * - If the session is 0, the audio output mix is visualized
+ * - If the session is not 0, the audio from a particular MediaPlayer or AudioTrack
+ *   using this audio session is visualized
+ * Two types of representation of audio content can be captured:
+ * - Waveform data: consecutive 8-bit (unsigned) mono samples by using the getWaveForm() method
+ * - Frequency data: 8-bit magnitude FFT by using the getFft() method
+ *
+ * The length of the capture can be retrieved or specified by calling respectively
+ * getCaptureSize() and setCaptureSize() methods. Note that the size of the FFT
+ * is half of the specified capture size but both sides of the spectrum are returned yielding in a
+ * number of bytes equal to the capture size. The capture size must be a power of 2 in the range
+ * returned by getMinCaptureSize() and getMaxCaptureSize().
+ * In addition to the polling capture mode, a callback mode is also available by installing a
+ * callback function by use of the setCaptureCallBack() method. The rate at which the callback
+ * is called as well as the type of data returned is specified.
+ * Before capturing data, the Visualizer must be enabled by calling the setEnabled() method.
+ * When data capture is not needed any more, the Visualizer should be disabled.

+// Right now, we just take the PTS of the last sample queued, and check to see
+// if its presentation time is within kAboutToUnderflowThreshold from now.  If
+// it is, then we say that we are about to underflow.  This decision is based on
+// two (possibly invalid) assumptions.
+//
+// 1) The transmitter is leading the clock by more than
+//    kAboutToUnderflowThreshold.
+// 2) The delta between the PTS of the last sample queued and the next sample
+//    is less than the transmitter's clock lead amount.
+//
+// Right now, the default transmitter lead time is 1 second, which is a pretty
+// large number and greater than the 50mSec that kAboutToUnderflowThreshold is
+// currently set to.  This should satisfy assumption #1 for now, but changes to
+// the transmitter clock lead time could effect this.
+//
+// For non-sparse streams with a homogeneous sample rate (the vast majority of
+// streams in the world), the delta between any two adjacent PTSs will always be
+// the homogeneous sample period.  It is very uncommon to see a sample period
+// greater than the 1 second clock lead we are currently using, and you
+// certainly will not see it in an MP3 file which should satisfy assumption #2.
+// Sparse audio streams (where no audio is transmitted for long periods of

+ *  Name        : dB_to_Lin32()
+ *  Input       : Signed 16-bit integer
+ *                  MSB (16) = sign bit
+ *                  (15->05) = integer part
+ *                  (04->01) = decimal part

+ *  Returns     : Lin value format 1.16.15
+ *  Description :
+ *  Remarks     :  Makes an approximation to the conversion by counting the number
+ *                 of 6dB steps for use as shifts and then interpolates with a remainder
+ *                 with the equation:
+ *
+ *                 Correction = (Remainder / 1.5029) - (Remainder^2 / 6)
+ *
+ *                 The two coefficients are scaled from 0x40000000 in 96 steps and calculated
+ *                 as follows:
+ *
+ *                 FIRST_COEF  = 0x80000000 / (96 * 1.5029)
+ *                 SECOND_COEF = 0x80000000 / (96^2 * 6)

+For gain, the LFO generates a value that modulates in terms
+of dB. However, we use a linear gain value, so we must convert
+the LFO value in dB to a linear gain. Normally, we would use
+linear gain = 10^x, where x = LFO value in dB / 20.
+Instead, we implement 10^x using our 2^x approximation.
+because
+
+  10^x = 2^(log2(10^x)) = 2^(x * log2(10))
+
+so we need to multiply by log2(10) which is just a constant.
+Ah, but just wait -- our 2^x actually doesn't exactly implement
+2^x, but it actually assumes that the input is in cents, and within
+the 2^x approximation converts its input from cents to octaves
+by dividing its input by 1200.
+
+So, in order to convert the LFO gain value in dB to something
+that our existing 2^x approximation can use, multiply the LFO gain
+by log2(10) * 1200 / 20
+
+The divide by 20 helps convert dB to linear gain, and we might
+as well incorporate that operation into this conversion.
+Of course, we need to keep some fractional bits, so multiply
+the constant by NUM_EG1_FRAC_BITS

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+ FUNCTION DESCRIPTION
+
+ This function steps through all of the tools that are applied on a
+ scalefactor band basis.
+
+ The use of M/S stereo is checked for.  For M/S decoding to take
+ place, ms_mask_map must be TRUE for that particular SFB, AND the Huffman
+ codebook used must be < NOISE_HCB.

+ FUNCTION DESCRIPTION
+
+    This function applies either the TNS forward or TNS inverse filter, based
+    on inverse_flag being FALSE or TRUE, respectively.
+
+    For the TNS forward filter, the data fed into tns_ar_filter is normalized
+    all to the same q-format.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    The input, coef, should use all 32-bits, else the scaling by tns_ar_filter
+    may eliminate the data.

+ FUNCTION DESCRIPTION
+
+ This function is only invoked when short windows are present. It calculates
+ the number of groups in one frame, and the scalefactor bandwidth of each
+ scalefactor band in each group.
+ All windows within one group share the same scalefactors and are interleaved
+ on a scalefactor band basis. Within each group, the actual length of one
+ scalefactor band equals to the number of windows times the number of
+ coefficients in a regular scalefactor band.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall replace the contents of pFrameInfo->frame_sfb_top
+ with the cumulative bandwidth of each scalefactor band in each group

+ FUNCTION DESCRIPTION
+
+   These functions are used to decode huffman codewords from the input
+   bitstream using combined binary search and look-up table approach.
+
+   First the codewords are grouped and the input symbol is determined
+   which group it belongs. Then within that group, a look-up table is
+   used to determine which codeword the symbol is.
+   The table is created by ordering the codeword in the table according to their
+   normalized shifted binary value, i.e., all the codewords are left
+   shifted to meet the maximum codelength. Example, max codelength is
+   10, the codeword with lenth 3 will left shift by 7.
+   The binary values of after the shift are sorted.
+   Then the sorted table is divided into several partition.
+   At the VLC decoding period, input is read in at max codelenght.
+   The partition is decided using if-else logic.
+   Inside each partition, a look-up table is used to map the input value
+   to a correct symbol. Table entries can appear to be repeated according
+   to the humming distance between adjacent codewords.

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    quantSpec[] = array of quantized compressed spectral coefficients, of
+                  data type Int and length sfbWidth.
+
+    sfbWidth    = number of array elements in quantSpec and the output array
+                  coef, data type Int.
+
+    coef[]      = output array of uncompressed coefficients, stored in a
+                  variable Q format, depending on the maximum value found
+                  for the group, array of Int32, length sfbWdith to be
+                  overwritten.
+
+    QFormat     = the output Q format for the array coef[].
+
+
+    scale       = scaling factor after separating power of 2 factor out from
+                  0.25*(sfb_scale - 100), i.e., 0.25*sfb_scale.
+
+    maxInput    = maximum absolute value of quantSpec.
+
+ Local Stores/Buffers/Pointers Needed: None.
+
+ Global Stores/Buffers/Pointers Needed:
+    inverseQuantTable = lookup table of const integer values to the one third
+                power stored in Q27 format, in file iquant_table.c, const
+                array of UInt32, of size 1025.
+
+ Outputs: None
+
+ Pointers and Buffers Modified:
+    coef[] contents are overwritten with the uncompressed values from
+    quantSpec[]
+
+
+
+
+ Local Stores Modified: None.
+
+ Global Stores Modified: None.
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function performs the inverse quantization of the spectral coeficients
+ read from huffman decoding. It takes each input array value to the four
+ thirds power, then scales it according to the scaling factor input argument
+ ,and stores the result in the output array in a variable Q format
+ depending upon the maximum input value found.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall not have static or global variables.

+ * Processing in this function is performed in these steps:
+ *
+ * 1) Find the overall Q format for the entire group of inputs. This consists
+ *    of:
+ *    a) Finding the maximum input
+ *    b) estimate the maximum output
+ *    c) Using the table, get max ^ (4/3), taking into account the table is
+ *       in q format.
+ * 2) For each array element, see if the value is directly inside the table.
+ *    a) If yes, just multiply by table value by itself, then shift as
+ *       appropriate.
+ *    b) If no, get an approximation (described below) for x ^ (1/3) by linearly
+ *       interpolating using lower values in the table, then multiply by a
+ *       correction factor, then multiply by x (see below).
+ *
+ * It more accurate to interpolate x ^ (1/3) then x ^ (4/3), so that is stored
+ * in the lookup table. For values not in the table, interpolation is used:
+ *
+ *  We want y = x ^ (4/3) = x * (x ^ (1/3))
+ *
+ *  Let     x = w * (2 ^ m)  where m is a constant, = ORDER
+ *
+ *  then     x ^ (1/3) = w ^ (1/3) * (2 ^ (m/3))
+ *
+ *  w is most likely not an integer, so an interpolation with floor(w) and
+ *  ceil(w) can be performed to approximate w ^ (1/3) by getting values out of
+ *  the table. Then to get x ^ (1/3), multiply by FACTOR. If m = 0, 3, 6,
+ *  then FACTOR is a simple power of 2, so a shift can do the job.
+ *
+ *  The actual code employs some more tricks to speed things up, and because
+ *  the table is stored in Q format.
+ *
+ *  Rather than saving the sign of each input, the unsigned value of
+ *  abs(x) ^ (1/3) is multiplied by the signed input value.

+ REVISION HISTORY
+
+ Description:
+            (1) Eliminated search for max in the main loop.
+            (2) Reduced precision on w_256rx4 from Q15 to Q10
+
+ Description:
+            (1) Created function fft_rx4_long_no_max to overcome LTP problem.
+
+ Description:
+            (1) Modified shift so the accumulation growths faster than the
+                downshift, so now the input can be as high as 1.0 and saturation
+                will not occurre. The accumulation times the Q10 format will
+                never exceed 31 bits. This increases precision
+            (2) Eliminated unneeded data moves, used before for max search.

+ FUNCTION DESCRIPTION
+
+    Fast Fourier Transform, radix 4 with Decimation in Frequency and block
+    floating point arithmetic.
+    The radix-4 FFT  simply divides the FFT into four smaller FFTs. Each of
+    the smaller FFTs is then further divided into smaller ones and so on.
+    It consists of log 4 N stages and each stage consists of N/4 dragonflies.
+
+    An FFT is nothing but a bundle of multiplications and summations which
+    may overflow during calculations.
+
+
+    This routine uses a scheme to test and scale the result output from
+    each FFT stage in order to fix the accumulation overflow.
+
+    The Input Data should be in Q13 format to get the highest precision.
+    At the end of each dragonfly calculation, a test for possible bit growth
+    is made, if bit growth is possible the Data is scale down back to Q13.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    This function should provide a fixed point FFT for an input array
+    of size 256.

+    An FFT is nothing but a bundle of multiplications and summations which
+    may overflow during calculations.
+
+
+    This routine uses a scheme to test and scale the result output from
+    each FFT stage in order to fix the accumulation overflow.
+
+    The Input Data should be in Q13 format to get the highest precision.
+    At the end of each dragonfly calculation, a test for possible bit growth
+    is made, if bit growth is possible the Data is scale down back to Q13.
+
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    This function should provide a fixed point FFT for an input array
+    of size 64.

+ REVISION HISTORY
+
+ Description:  Reduce the accuracy of w_256rx4 and w_512rx2 to Q10 format.
+            Try to to pack sin and cos into one 32-bit number to reduce the
+            memory access, but doesn't help in speed, so commented out for now.
+
+ Description:
+        (1) Reduced precision of w_64rx4 from Q15 to Q12.
+        (2) Increased precision of w_512rx2 from Q10 to Q13, Both changes
+            increase overall decoder precision
+
+ Description:
+        (1) per code review comment, added description for table generation
+        (2) modified definition of w_64rx4 from Int to Int16

+ FUNCTION DESCRIPTION
+
+ This module scans the bitstream for a syncword of any length between 1 and 32.
+ If certain bits in the syncword are to be ignored, that bit position should
+ be set to 0 in both parameters *(pSyncword) and syncword_mask.  This allows
+ for a syncword to be constructed out of non-contiguous bits.
+
+ Upon finding the syncword's position in the bitstream, a value denoting the
+ syncword's degree of deviance from being byte-aligned (byte_align_offset)
+ is set in the structure pointed to by pInputStream.
+ This is a value between 0 and 7.
+
+ If no syncword is found, the function returns status == ERROR.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ "Don't care" bits must be set to '0' in both *(pSyncword) and syncword_mask.
+
+ This function should not be called if there are less than
+ (8 + syncword_length) bits in the buffer.

+ FUNCTION DESCRIPTION
+
+    fwd_long_complex_rot() performs the pre complex rotation for the MDCT
+    for the case of long windows. It also performs digit reverse ordering of
+    the first and second halves of the input vector "Data_in", as well as
+    reordering of the two half vectors (following radix-2 decomposition)
+    Word normalization is also done to ensure 16 by 16 bit multiplications.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    fwd_long_complex_rot() should execute a pre-rotation by
+    exp(-j(2pi/N)(k+1/8)), digit reverse ordering and normalization

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to remove instances of pow() and sqrt(), and
+ optimized for inclusion in fixed-point version of decoder.
+
+ Description:  Modified to include comments/optimizations from code review.
+ Also, declared appropriate variables as type "const"
+
+ Description:  Adopted strategy of "one q-format per sfb" strategy, which
+ eliminated the array q-format from this function.  The q-format the
+ random vector is stored in is now returned from the function.
+
+ Description:  Completely redesigned the routine to allow a simplified
+        calculation of the adjusted noise, by eliminating the dependency
+        on the band_length. Added polynomial approximation for the
+        function 1/sqrt(power). Updated comments and pseudo-code
+
+ Description:  Modified function description, pseudocode, etc.
+
+ Description:
+    Modified casting to ensure proper operations for different platforms
+
+ Description:
+    Eliminiated access to memory for noise seed. Now a local variable is
+    used. Also unrolled loops to speed up code.
+
+ Description:
+    Modified pointer decrement to a pointer increment, to ensure proper
+    compiler behavior

+ FUNCTION DESCRIPTION
+
+ This function generates a vector of uniformly distributed random numbers for
+ the PNS block.  The random numbers are each scaled by a scale_factor,
+ defined in Ref(2) as
+
+ 2^(scale_factor/4)
+ ------------------
+  sqrt(N*MEAN_NRG)
+
+ where N == band_length, and MEAN_NRG is defined as...
+
+         N-1
+         ___
+     1   \
+    ---   >    x(i)^2
+     N   /__
+         i=0
+
+ And x is the unscaled vector from the random number generator.
+
+ This function takes advantage of the fact that the portion of the
+ scale_factor that is divisible by 4 can be simply accounted for by varying
+ the q-format.
+
+ The scaling of the random numbers is thus broken into the
+ equivalent equation below.
+
+ 2^(scale_factor%4)   2^(floor(scale_factor/4))
+ ------------------ *
+  sqrt(N*MEAN_NRG)
+
+
+ 2^(scale_factor%4) is stored in a simple 4-element table.
+ 2^(floor(scale_factor/4) is accounted for by adjusting the q-format.
+ sqrt(N*MEAN_NRG) is calculated and implemented via a polynomial approximation.
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall produce uniformly distributed random 32-bit integers,
+ with signed random values of average energy equal to the results of the ISO
+ code's multiplying factor discussed in the FUNCTION DESCRIPTION section.
+
+ Please see Ref (2) for a detailed description of the requirements.

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description:  Change to PV template, remove default config parameter,
+               move some functionality into get_prog_config().
+
+ Description: Update per code review
+              1) Add parameter pScratchPCE
+              2) Change way ADIF_ID is read in.
+              3) Fix comments
+              4) ADD a test for status != SUCCESS in loop.
+
+ Description: The ADIF_Header has now been delegated to the "scratch memory"
+ union.  This change inside s_tDec_Int_File.h had to be reflected here also.
+
+ Description: Updated the SW template to include the full pathname to the
+ source file and a slightly modified copyright header.

+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function reads in the ADIF Header found at the front of ADIF streams.
+ If the header is not found an error is returned. An ADIF header can contain
+ from zero to sixteen program configuration elements (PCE). This function, and
+ the rest of the library, saves and uses the first PCE found.

+ REQUIREMENTS
+
+ Function shall not use static or global variables.

+ FUNCTION DESCRIPTION
+
+ Acronym Definitions
+ ADTS  Audio Data Transport Stream
+ CRC   Cyclic Redundancy Code
+
+ This function calls find_adts_syncword to find the next ADTS header.  Until
+ three consistent headers have been read, the syncword used for detection
+ consists of the 12-bit syncword and the 2-bit Layer.  After three consistent
+ headers are read, the entire fixed header is used for a robust 28-bit
+ syncword.
+
+ Configuration information is then extracted from the bitstream.
+
+ The bitstream information is packed as follows.
+ Comments about the correct interpretation of these bits are contained within
+ the code.
+

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    audioObjectType = MP4 Audio Object Type for the current song. Only if
+                    this is set to LTP (MP4AUDIO_LTP) will long term
+                    prediction bits be retrieved. Data type
+                    tMP4AudioObjectType, which is an enumeration, which in
+                    turn is an Int.
+
+    pInputStream  = pointer to a BITS structure, used by the function getbits
+                    to provide data. This is the second parameter to this
+                    function to match its position in getbits().
+                    Data type pointer to BITS structure
+
+    common_window = field read in huffdecode, which tells whether information
+                    is shared between the left and right channel. Long term
+                    prediction (LTP) data is NOT shared even if its a common
+                    window, so this flag is needed to see if another set of
+                    LTP possibly needs to be read. If this flag is false,
+                    pSecondLTPStatus is not touched, it could be NULL if
+                    need be. Data type Bool, which is Int.
+
+    pWindowSequence = pointer to where the the window type of the current
+                    frame and channel should be placed, of data type
+                    WINDOW_SEQUENCE, which is Int. It can take on one
+                    of four values: ONLY_LONG_SEQUENCE, LONG_START_SEQUENCE,
+                    EIGHT_SHORT_SEQUENCE, LONG_STOP_SEQUENCE,
+
+    pWindowShape =  pointer to where the window shape for the current frame
+                    and channel should be placed, of data type WINDOW_SHAPE,
+                    which is Int. It can take on the one of these two values:
+                    SINE_WINDOW, KAISER_BESSEL_WINDOW. It is used in the
+                    "filterbank" section of decoding.
+
+    group         = array that holds the index of the first window in each
+                    group. Data type array of Int, eight elements.
+
+    p_max_sfb     = pointer to where the maximum number of scale factor bands
+                    for the current frame and channel will be placed. Data
+                    type of pointer to Int.
+
+    p_winmap      = array of pointers to all of the possible four window
+                    configurations. This parameter did not need to be pointers,
+                    and could be changed in the future. Data type array of pointers
+                    to FrameInfo structures, length 4.
+
+    pFirstLTPStatus = pointer to a structure where the first LTP
+                    information will be stored. It would be confusing and wrong
+                    to call this left LTP status since if common_window = FALSE,
+                    this function will be called twice - once for the left, once
+                    for the right. It could be done, but extra conditional code
+                    would need to be done.
+                    Data type pointer to LT_PRED_STATUS structure.
+
+    pSecondLTPStatus = pointer to where the right channel of LTP
+                    information will be stored only if common_window is non-zero.
+                    Data type pointer to LT_PRED_STATUS structure.
+
+ Local Stores/Buffers/Pointers Needed: None.
+
+ Global Stores/Buffers/Pointers Needed: None.
+
+ Outputs:
+    status  = 0 implies no error occurred, non-zero otherwise.
+
+ Pointers and Buffers Modified:
+    pInputStream contents are modified in such a way that the number of bits
+        read increases.
+    pWindowSequence contents are updated with the current window for this
+        frame and channel
+    group[] contents will be modified to grouping information. See getgroup
+        source code for a better description of what this is.
+    p_max_sfb contents will be updated with the maximum scale factor bands
+        for this frame and channel.
+    pFirstLTPStatus contents may be updated if the stream has long term
+        prediction information.
+    pSecondLTPStatus contents may be updated if common_window != 0 and LTP data
+        is present.
+
+
+ Local Stores Modified: None
+
+ Global Stores Modified: None
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function retrieves the individual channel stream (ICS) information
+ from the bitstream. The information read for the current
+ frame and channel is:
+ - window sequence
+ - window shape for use in the filter bank
+ - number of scale factor bands
+ - long term predication (LTP) information
+ - grouping information
+
+ This function does NOT support MPEG2 style AAC Frequency Domain Predictor,
+ not to be confused with LTP (Long Term Prediction). If such data is found
+ to be on the file an error is generated.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function is not to use static or global data.

+ FUNCTION DESCRIPTION
+
+ This function reads from the input stream to memory for a temporary
+ program configuration element (PCE). If the PCE read is the first
+ encountered it is saved. Or, if the tag of the PCE read matches the tag of
+ the first PCE encounted, it is saved as well. This is a mechanism for
+ changing the sampling rate.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall not use static or global variables.

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description: Put into PV format
+
+ Description: 1) Change loop to use pointers.
+              2) Rename to from get_nec_nc to get_pulse_data
+
+ Description: Changes per code review
+              1) Fix pathname
+              2) Read in two fields to save call to getbits
+              3) Change how pPulseInfo->number_pulse is stored.
+
+ Description: Placed typecast to Int in places where UInt->Int
+
+ Description: Replace some instances of getbits to get9_n_lessbits
+              when the number of bits read is 9.
+
+ Who:                                  Date:

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+     pInputStream = pointer to a BITS structure, used by the function getbits
+                   to provide data. Data type pointer to BITS structure
+
+     pPulseInfo   = pointer to pulse data structure to be filled with data
+                    concerning pulses in the frequency domain.
+                    Data type pointer to PulseInfo
+
+ Local Stores/Buffers/Pointers Needed: None
+
+ Global Stores/Buffers/Pointers Needed: None
+
+ Outputs:
+     status       = return value, zero signifies success, non-zero otherwise.
+                    Presently this function only returns a success, error
+                    checking may be added later.
+                    Data type Int.
+
+ Pointers and Buffers Modified:
+
+    pPulseInfo contents are updated with pulse information. Specifically,
+    pPulseInfo->number_pulse with the number of pulses found, and
+    pPulseInfo->pulse_start_sfb is set to the first scale factor band.
+    Then pPulseInfo->pulse_offset and pPulseInfo->pulse_amp are filled
+    with data. For these array, only the number of pulses defined will be
+    set, those values beyond the number of pulses will retain their previous
+    value and should not be read from.
+    Note: The value in pPulseInfo->number_pulse is different by a value of
+          one from the original ISO code.
+
+    pInputBuffer contents are updated to the next location to be read from
+        the input stream.
+
+ Local Stores Modified: None
+
+ Global Stores Modified: None
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function fills in the pulse data structure with information to be used
+ later for restoring pulses in the spectrum.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall not use global or static variables.

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description:  Brought code in-line with PV standards.  Some minor
+               optimizations (count-down for loops, etc.) were made.
+
+ Description:  Made cosmetic changes as suggested during review.  Also,
+ changed calculation of s_mask and n_mask from table-based to being
+ calculated based on res_index.  Also, the flag coef_res was changed
+ from having a range of [3,4] to having a range of [0,1], which corresponds
+ exactly with the true value that is passed via the bitstream.
+
+ Description:  Modified to use more efficient TNS memory structure.
+
+ Description: Updated to reflect more efficient usage of memory by the TNS
+ filters.
+
+ Description: Updated the SW template to include the full pathname to the
+ source file and a slightly modified copyright header.
+
+ Description: Moved pInputStream to be the 2nd parameter, for a slight
+ optimization on some platforms.
+
+ Description: Moved pSfbTop outside of the loops, since its value does
+ not change.
+
+ Description: Replace some instances of getbits to get1bits
+              when only 1 bit is read.

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    FrameInfo *pFrameInfo
+        Pointer to structure that holds information about each block.
+        (long block flag,
+         number of subblocks,
+         scalefactor bands per subblock, etc.)
+
+    BITS *pInputStream
+        Pointer to a BITS structure that is
+        passed on to function getbits to pull information from the bitstream.
+
+    TNS_Frame_info *pTnsFrameInfo
+        Pointer to filter data structure - to be populated by this function.
+
+ Local Stores/Buffers/Pointers Needed:
+    None
+
+ Global Stores/Buffers/Pointers Needed:
+    None
+
+ Outputs:
+    None
+
+ Pointers and Buffers Modified:
+    TNS_frame_info *pTnsFrameInfo
+
+    pTnsFrameInfo->n_filt = Number of tns filters to be applied to the data.
+
+    pTnsFrameInfo->filt[]->order = The order of each individual TNS filter.
+
+    pTnsFrameInfo->filt[]->coef_res = The resolution of the filter coefficients
+
+    pTnsFrameInfo->filt[]->start_band = start of spectral band
+
+    pTnsFrameInfo->filt[]->stop_band = end of spectral band
+
+    pTnsFrameInfo->filt[]->coef[] = Each filter's coefficients are filled with
+    data read from the input bitstream.
+
+    pTnsFrameInfo->filt[]->direction = A flag is set for each TNS filter.
+
+    If the direction flag (on the bitstream) = 0, then the filter
+    is applied to the block of spectral data in normal (upward) fashion.
+
+    If the direction flag (on the bitstream) = 1, then the filter
+    is applied in a reverse (downward) fashion.
+    (Starting with the last element in the block of data.)
+
+    The value stored in filt[]->direction maps the values [0,1] to [1,-1] for
+    a more intuitive storage of this flag's meaning.

+ FUNCTION DESCRIPTION
+
+ This function reads the TNS filter information from the bitstream, and stores
+ the filter order, LPC coefficients, and the number of TNS filters to
+ be applied in the structure TNS_frame_info.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This code should match the ISO code in functionality, with the exception
+ that coef_res has range of [0,1] (PV code) instead of [3,4] (ISO code)
+
+ coef_res is only used by tns_decode_coef.

+ FUNCTION DESCRIPTION
+
+ This function reads the window grouping information associated with an
+ Individual Channel Stream (ICS). If the window sequence is
+ EIGHT_SHORT_SEQUENCE, scalefactor grouping information is transmitted. If a
+ set of short windows form a group then they share scalefactors, intensity
+ positions and PNS information. The first short window is always a new group
+ so no grouping bit is transmitted. Subsequent short windows are in the same
+ group if the associated grouping bit is 1. A new group is started if the
+ associated grouping bit is 0.
+ The pointer pGroup points to an array that stores the first window index
+ of next group. For example, if the window grouping is:
+
+ window index:    |  0  |  1  |  2  |  3  |  4  |  5  |  6  |  7  |
+ grouping    :    |<-   0   ->|  1  |<-    2        ->|<-   3   ->|
+
+ Then:
+
+    group[]  :    |     2     |  3  |        6        |     8     |
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function should replace the contents of the array pointed to by pGroup
+ with the first window indexes of groups starting from the second group.

+ Description:
+ (1) Added #include of "e_HuffmanConst.h"
+     Previously, this function was relying on another include file
+     to include "e_HuffmanConst.h"
+
+ (2) Updated the copyright header.
+
+ (3) Added #include of <stdlib.h> for NULL macro definition.
+
+ Description:
+ (1) Removed the first parameter to getics.c  This extra
+     FrameInfo was not needed, the contents of winmap can be used.
+ (2) Removed the memcpy of the data from winmap to the temporary
+     FrameInfo.
+
+ Description: Replace some instances of getbits to get1bits
+              when only 1 bit is read.

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+               Replaced for-loop style memory initialization with memset()
+
+ Description: (1) Modified to bring code in-line with PV standard
+              (2) Removed multiple returns, Replaced multiple 'if's with
+                  switch
+
+ Description: (1) Modified per review comments
+              (2) increment pointer pMask after memset
+
+ Description: Make the maximum number of bits requested from getbits
+              become a constant.
+
+ Description: Typecast 1 to UInt32 for bitmask to avoid masking on a 16-bit
+              platform
+
+ Description: Replace some instances of getbits to get9_n_lessbits
+              when the number of bits read is 9 or less.

+ FUNCTION DESCRIPTION
+
+ This function reads the Mid/Side(MS) mask information from the input
+ bitstream. If the mask_present field is equal to 2, the mask bits is set to
+ 1 for the entire frame. If mask_present has a value of 0, the function
+ returns 0, If mask_present is set to 1, the Mid/Side(MS) information is
+ read from the input stream. When mask_present is 3, an error code (-1) is
+ generated.
+ The Mid/Side(MS) information is later used for mixing the left and right
+ channel sounds. Each scalefactor band has its own MS information.
+
+ (ISO comments: read a synthesis mask,  read a synthesis mask uses
+                EXTENDED_MS_MASK and grouped mask )
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall replace the contents of pMask with the MS information
+ of each scalefactor band

+   The binary values of after the shift are sorted.
+   Then the sorted table is divided into several partition.
+   At the VLC decoding period, input is read in at max codelenght.
+   The partition is decided using if-else logic.

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description:  Change variable names for clarity,
+               change variables 'base', 'sect_len_inc', and 'esc_val' to
+               UChar type.
+
+ Description:  Add "if ((pSect[-1] % sfb_per_win) > max_sfb)" statement to
+               detect the error condition.
+               add more white space.
+
+ Description: eliminated "pSect[-1]%sfb_per_win" operation
+
+ Description: eliminated "pSect[-1]%sfb_per_win" operation
+
+ Description: (1) Pass in SectInfo pSect
+              (2) put BITS *pInputStream as second parameter
+
+ Description:  Fix a failure for thrid party AAC encoding.
+               The problem came when the total and the
+               maximun number of active scale factor bands do not coincide.
+               This is a rare situation but produces a problem when decoding
+               encoders that tolerate this.
+
+ Description: Replace some instances of getbits to get9_n_lessbits
+              when the number of bits read is 9 or less and get1bits
+              when only 1 bit is read.

+                      ...
+
+    Int     sectbits  =   array that defines the number of bits
+                          used for expressing the escape value of
+                          section length
+
+    Int     tot_sfb     = total number of sfb in one Frame

+
+    BITS    *pInputStream = pointer to input stream
+
+
+ Local Stores/Buffers/Pointers Needed:
+
+    UChar    base     = number of sfb in already detected sections
+
+    UChar    sect_len_inc = section length increment in number of sfbs'
+
+    UChar    esc_val  = escape value for section length
+
+    Int     bits     = number of bits needed for expressing section length
+
+
+ Global Stores/Buffers/Pointers Needed:
+
+
+ Outputs:
+
+    num_sect = total number of sections in one frame
+
+
+ Pointers and Buffers Modified:
+
+    UChar    *pSect = pointer to array where huffman codebook index and

+ FUNCTION DESCRIPTION
+
+ Background knowledge: 1024(960) coef's are separated into several sections,
+ each section is encoded with one single Huffman codebook, and each section
+ has a length of multiples of sfb.
+
+ max_sfb <= sfb_per_win <= tot_sfb
+ tot_sfb = total number of scalefactor bands in one frame (1024 coefs)
+
+ This function reads the codebook index and section boundaries (expressed
+ in number of sfb) from the input bitstream, store these information in
+ *pSect, and return the number of sections been detected. Returns 0 if there
+ is an error.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function should fill the array *pSect with section Huffman codebook
+ indexes and section boundaries

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description:  Change variable types.
+
+ Description:  (1) Modified to bring in-line with PV standards.
+               (2) Eliminated global_gain on stack,
+                   getics() has to define this parameter on its stack.
+               (3) Eliminated multiple returns
+               (4) Altered return logic of getics()
+               (5) Convert Real coef -> Int32 coef
+               (6) Move BITS *pInputStream to 2nd parameter of huffdecode.c
+                   and getics.c
+               (7) Pass pFrameInfo per channel, because two channels can have
+                   different windows
+
+ Description: (1) Eliminated function call to chn_config
+              (2) Eliminate widx calculation
+              (3) copy channel info from left to right when common_window
+                  is enabled
+              (4) add error checking of getmask return value
+
+ Description:  Change default_position to current_program
+
+ Description:  Remove prstflag
+
+ Description:  Modify call to get_ics_info
+
+ Description:  Modified so getmask is NOT called if the status returned
+ from get_ics_info indicates an error.
+
+ Description:
+ (1) Added include of "e_ElementId.h"
+     Previously, this function was relying on another include file
+     to include e_ElementId.h
+
+ (2) Updated the copyright header.
+
+ Description:  Modified to include usage of the new "shared memory" structures
+ defined in s_tDec_Int_File.h and s_tDec_Int_Chan.h
+
+ Description:
+ (1) Updated to reflect the fact that the temporary FrameInfo used by getics.c
+ was moved into the region of memory shared with fxpCoef.
+
+ Description:
+ (1) Removed first parameter to getics.  The temporary FrameInfo was
+     unnecessary.
+
+ Description: Replace some instances of getbits to get9_n_lessbits
+              when the number of bits read is 9 or less and get1bits
+              when only 1 bit is read.
+
+ Description: Relaxed tag verification. Some encoder do not match the tag
+              to the channel ID (as the standard request to differentiate
+              different channel), in our wireless work, with only mono
+              or stereo channel, this become restrictive to some encoders

+ FUNCTION DESCRIPTION
+
+  This function offers a framework for decoding the data of the next 1024
+  samples. It maps the channel configuration according to the id_syn_ele flag,
+  configures the channel information, and calls getics to do huffman decoding
+  The function returns 1 if there was an error
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function should set up the channel configuration for huffman decoding

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description: (1) Modified with new templates,
+              (2) Modified variable names for clarity
+              (3) adjusted variables of "for loop"
+              (4) eliminated multiple returns, use return valid
+
+ Description: (1) Change return logic: 0 if success, 1 if error
+              (2) Define SectInfo structure to store section codebook index
+                  and section boundary
+              (3) Substitute "switch" with "if- else if"
+              (4) move BITS *pInputStream to second pass-in parameter
+              (5) pass in huffBookUsed[] to save stack size
+
+ Description: (1) Remove pass in parameter Hcb pBook
+
+ Description: Use binary tree search in decode_huff_cw_binary
+
+ Description: Use decode_huff_scl function.

+ FUNCTION DESCRIPTION
+
+ This function first reads the Huffman codebook index of all sections within
+ one Frame. Then, depending on the huffman codebook index of each section,
+ the function decodes the scalefactors, and/or intensity positions
+ (INTENSITY_HCB, INTENSITY_HCB2), and/or noise energy (NOISE_HCB)
+ for every scalefactor band in each section.
+ The function returns 0 upon successful decoding, returns 1 if error.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function should replace the content of the array pFactors with the
+ decoded scalefactors and/or intensity positions and/or noise energy

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description: (1) Modified to keep in-line with PV standards
+              (2) Eliminated "continue" in if(sect_cb==ZERO_HCB||...)
+
+ Description: (1) Use SectInfo *pSect
+              (2) Convert 'Real' to 'Int32', float -> fixed-point
+              (3) move BITS *pInputStream to second parameter
+              (4) pass in quantSpec and tmp_spec, scratch shared with hufffac
+              (5) pass in FrameInfo *pLongFrameInfo, eliminate only_long_info
+
+ Description: (1) Eliminate parameter Hcb *book, because of eliminating
+                  function 'hufftab.c', Hcb hcbbook defined as a
+                  const structure in 'hcbtables.h'.
+              (2) Replace three nested 'for' loops with a for-while loop in
+                  the rescaling part.
+              (3) Change esc_iquant-> esc_iquant_fxp, call esc_iquant_fxp()
+                  by sfb
+
+ Description: Cleaned up include files.
+
+ Description:  Correct definition of stack variable "scale".
+        It was defined as Int, but it receives an UInt value,
+        this present a problem when Int is 16 bits and
+        the sign bit is not interpreted correctly. This does not
+        shows for 32-bit implementations. This problem manifest itself
+        as a flipping sign on some spectral coefficients (the ones
+        multiplied by 0x8000).
+
+ Description: Typecast b_low and b_high to 32-bits before multiplication, this
+              assures propoer compilation on a 16-bit platform (TI-C55x)
+
+ Description: Modified to speed up decode_huff_cw
+
+ Description: pass codebook index to decode_huff_cw, delete pointer to Huffman
+              structure
+
+ Description: keep memset to quantSpec, remove memset to temp_spec
+
+ Description: Modified per review comments
+
+ Description: Use Binary tree search in decode_huff_cw_binary
+
+ Description: Modified per review comments
+              (1) delete unused codes
+
+ Description: (1) Change the interface to decode huffman codeword.
+              (2) Move the scaling inside the inverse quantization.
+              (3) Change scaling factor accuracy to 10 bits.
+
+ Description:
+              (1) delete unused variable max_fac
+
+ Description: Addresses of huffman tables are now found by means of a
+              switch statement, this solve linking problem when using the
+              /ropi option (Read-only position independent) for some
+              compilers

+ FUNCTION DESCRIPTION
+
+ This function first reads the section info (codebook and boundary), then
+ decode the spectral coefficients if a spectral codebook is used.
+ If necessary, get the sign bits, ESC value or the NEC_pulse data. In case of
+ short window sequences, the decoded data is de-interleaved before
+ multiplied by scalefactors.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function should set the content of the array 'coef' with the inverse
+ quantized and rescaled value of spectral coefficients.

+ FUNCTION DESCRIPTION
+
+    The IMDCT is a linear orthogonal lapped transform, based on the idea of
+    time domain aliasing cancellation (TDAC).
+    IMDCT is critically sampled, which means that though it is 50% overlapped,
+    a sequence data after IMDCT has the same number of coefficients as samples
+    before the transform (after overlap-and-add). This means, that a single
+    block of IMDCT data does not correspond to the original block on which the
+    IMDCT was performed. When subsequent blocks of inverse transformed data
+    are added (still using 50% overlap), the errors introduced by the
+    transform cancels out.Thanks to the overlapping feature, the IMDCT is very
+    useful for quantization. It effectively removes the otherwise easily
+    detectable blocking artifact between transform blocks.
+
+    N = twice the length of input vector X
+    y = vector of length N, will hold fixed point IDCT
+    p = 0:1:N-1
+
+                    2   N/2-1
+            y(p) = ---   SUM   X(m)*cos(pi/(2*N)*(2*p+1+N/2)*(2*m+1))
+                    N    m=0
+
+    The window that completes the TDAC is applied before calling this function.
+    The IMDCT can be calculated using an IFFT, for this, the IMDCT need be
+    rewritten as an odd-time odd-frequency discrete Fourier transform. Thus,
+    the IMDCT can be calculated using only one n/4 point FFT and some pre and
+    post-rotation of the sample points.
+
+
+    where X(k) is the input with N frequency lines

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description:  Pass eight_short_info and the array 'sfbwidth128'.
+               Change function arguments' names for clarity
+
+ Description:  move sfb definitions to "sfb.h", and "sfb.c", eliminated
+               the function "huffbookinit.c"
+
+ Description:  Remove initialization of the never used array,
+               pFrameInfo->group_offs
+
+ Description:
+ (1) Changed "stdinc.h" to <stdlib.h> - this avoids linking in the math
+ library and stdio.h.  (All for just defining the NULL pointer macro)
+
+ (2) Updated copyright header.
+
+ Description: Updated the SW template to include the full pathname to the
+ source file and a slightly modified copyright header.
+
+ Description: Addresses of constant vectors are now found by means of a
+              switch statement, this solve linking problem when using the
+              /ropi option (Read-only position independent) for some
+              compilers

+ REVISION HISTORY
+
+ Description: Modified per review comments.
+
+ Description: Noticed that the code could be more efficient by
+ using some other method for storing the sign.  The code was changed to
+ use a signed Int to store the table, and an adjustment of the q-format to
+ reflect the difference between the data being shifted by 16 and the table
+ being stored in q-15 format.
+
+ Description: Updated pseudocode
+
+ Description: When the multiplication of two 16-bits variables is stored in
+              an 32-bits variable, the result should be typecasted explicitly
+              to Int32 before it is stored.

+ FUNCTION DESCRIPTION
+
+ This function applies Intensity Stereo, generating data on the right channel
+ that is derived from data on the Left.  A scalefactor is applied using the
+ following formula...
+
+ RightCh = LeftCh*0.5^(scalefactor/4)
+
+ This function works for one scalefactor band, which may belong to a group.
+ (i.e. the same scalefactor band repeated across multiple windows belonging
+  to one group.)
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ codebook must be either INTENSITY_HCB or INTENSITY_HCB2 when this function
+ is called.
+
+ ms_used must be 1 when TRUE, 0 when FALSE.
+
+ wins_in_group falls within the range [1-8]

+ FUNCTION DESCRIPTION
+
+    inv_long_complex_rot() performs the complex rotation for the inverse MDCT
+    for the case of long windows. It also performs digit reverse ordering of
+    the first and second halves of the input vector "Data_in", as well as
+    reordering of the two half vectors (following radix-2 decomposition)
+    Word normalization is also done to ensure 16 by 16 bit multiplications.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    inv_long_complex_rot() should execute a post-rotation by
+    exp(-j(2pi/N)(k+1/8)), digit reverse ordering and word normalization

+ REVISION HISTORY
+
+ Description: Made changes based on comments and experiment results.
+
+ Description: Passed in buffer sizes based on review comments and prototype
+              agreements.
+
+ Description: 1. Passed in "weight_index" instead of "weight".
+              2. Added weight table.
+
+ Description: 1. Removed some passed in buffer size variables since they are
+                 not used for long window.
+              2. Modified comments format.
+
+ Description:
+    Modified casting to ensure proper operations for different platforms
+
+ Description:
+    Implemented circular buffer techniques, which save 4096 memmoves per
+    frame.
+
+ Description:
+    Implemented some optimizations found during the code review of this
+    module.  The optimizations related to the rules on the range of
+    ltp_buffer_index and num_samples, which allows for a simpler
+    code construct to be used in the processing of the predicted samples.
+
+ Description:
+    Add max calculation on the filter implementation, this to eliminate
+    function buffer_adaptation() on the time to frequency transformation.
+    Function interface changed. It now return the amount of shifting needed
+    to garb only the top 16 MSB.
+
+ Description:
+     Replace clearing memory with for-loop with pvmemset function
+
+ Description:
+
+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    win_seq = type of window sequence (WINDOW_SEQUENCE).
+
+    weight_index = index (Int) of LTP coefficient table for all windows in
+                   current frame.
+
+    delay = buffer (Int) containing delays for each window.
+
+    buffer = history buffer (Int16) containing the reconstructed time domain
+             signals of previous frames.
+
+    buffer_offset = value (Int) that indicates the location of the first
+                    element in the LTP circular buffer.  (Either 0 or 1024)
+
+    time_quant    = filterbank buffer (Int32) This buffer is used by the
+                    filterbank, but it's first 1024 elements are equivalent
+                    to the last 1024 elements in the conventionally
+                    implemented LTP buffer.  Using this buffer directly avoids
+                    costly duplication of memory.
+
+    predicted_samples = buffer (Int32) with length of 2048 to hold
+                        predicted time domain signals.
+
+    buffer_index = index into buffer where the first sample of data from
+                   the frame (t-2) (two frames ago) resides.  (Int)
+
+    frame_length = length of one frame, type of Int.
+
+ Local Stores/Buffers/Pointers Needed:
+    None
+
+ Global Stores/Buffers/Pointers Needed:
+    None
+
+ Outputs:
+    Amount of shifting needed to grab the top 16 MSB from teh predicted buffer
+
+ Pointers and Buffers Modified:
+    predicted_samples contents are the newly calculated predicted time
+    domain signals
+
+ Local Stores Modified:
+    None
+
+ Global Stores Modified:
+    None
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ Long term prediction (LTP) is used to reduce the redundancy of a signal
+ between successive coding frames. This function performs prediction by
+ applying 1-tap IIR filtering to calculate the predicted time domain
+ signals of current frame from previous reconstructed frames stored in
+ time domain history buffer.
+
+ The equation used for IIR filter is as following.
+
+            y(n) = weight * x(n - delay)
+
+    where   y(n) ----- predicted time domain signals
+            x(n) ----- reconstructed time domain signals
+            weight ----- LTP coefficient
+            delay ----- optimal delay from 0 to 2047

+ REVISION HISTORY
+
+ Description: Modified prototype with array size passed in per review
+              comments.
+
+ Description: Changed prototype with "weight_index" instead of "weight".
+
+ Description: Removed some passed in buffer size variables since they are
+              not being used for long window.
+
+ Description: Temporarily define LTP_Q_FORMAT for current release.
+              Need to change function prototype and pass out Q_format
+              information later.
+
+ Description: Updated function prototype to reflect the usage of a
+ circular buffer by LTP.
+
+ Description:  Updated function interface with new return type

+ REVISION HISTORY
+
+ Description: Made the following changes based on the review comments.
+              1. Separated "shift_factor>=0" on line 395 to "shift_factor>0"
+                 and "shift_factor=0" two cases.
+              2. Added comments on line 393 to explain why factor 2 is being
+                 used to calculate shift_factor.
+              3. Added comments for short window implementation.
+              4. Changed "*(pPredicted_spectral++) = *pPredicted_spectral>>2"
+                 to "*(pPredicted++)>>=2" although they are the same.
+              5. Changed pseudo code "X+=Y" to "X=X+Y".
+              6. Fixed ending comment of "for" loop.
+              7. Passed in the size of the array and deleted some of the
+                 include files.
+
+ Description: Unroll the loops.
+
+ Description: Changed index "wnd" in previous line 584 with "wnd_offset"
+              and made other correspondent changes to the code.
+
+
+ Description: Based on Ken's suggestion, modified the function with the
+              passing-in Q format as scalefactor band basis in order to
+              simplify TNS block functions.
+
+ Description: Optimization.
+
+ Description: Made changes based on review comments.
+              1. Changed misspellings.
+              2. Changed win_sfb_top[] from two dimensional array to one
+              dimensional array and correspondently changed the code.
+              3. Changed function prototype to remove some redundant
+              informations.
+              4. Fixed the adjusting Q format part code.
+              5. Fixed lines 825, 826 with correct updating pointers.
+
+ Description: Due to TNS and LTP Q format issue, added code to adjust
+              predicted_spectral() to maximum resolution before perform
+              long term synthesis.
+
+ Description: Modified based on review comments.
+
+ Description: Changed "max" data type from UInt to UInt32.
+
+ Description: Changed so that nothing is done for the case of "all zero"
+ data coming from the output of Trans4m_time_2_freq. Also, included more
+ efficient calculation of the abs(x).  And, I updated the pseudocode.
+
+ Description: Use an auxiliary variable temp, to avoid using the same
+    pointer and a post-increment pointer in the same line. This may not
+    work with all compilers.

+ FUNCTION DESCRIPTION
+
+ This function performs long term synthesis using transmitted spectral
+ coeffients or errors and predicted spectral components.
+
+ Long term synthesis is part of long term prediction (LTP) which is used to
+ reduce the redundancy of a signal between successive coding frames. The
+ functionality of long term synthesis is to reconstruct the frequency domain
+ spectral by adding the predicted spectral components and the transmitted
+ spectral error when prediction is turned on.

+
+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Modified to pass variables by reference to eliminate use
+               of global variables.
+
+ Description:  First round of optimizations.
+
+ Description:  pInputStream is now the 2nd parameter to this function.
+
+ Description:  Changed to work with MT's new get_ics_info.c function, which
+ only calls lt_decode if LTP is enabled.  This removes one grab from the
+ bitstream and one "if" from this code.  Also, changed setting of weight.
+ Now, rather than setting the actual weight, I only set the index into
+ a table in this function.
+
+ Description: Replace some instances of getbits to get9_n_lessbits
+              when the number of bits read is 9 or less and get1bits
+              when only 1 bit is read.

+ FUNCTION DESCRIPTION
+
+    The MDCT is a linear orthogonal lapped transform, based on the idea of
+    time domain aliasing cancellation (TDAC).
+    MDCT is critically sampled, which means that though it is 50% overlapped,
+    a sequence data after MDCT has the same number of coefficients as samples
+    before the transform (after overlap-and-add). This means, that a single
+    block of MDCT data does not correspond to the original block on which the
+    MDCT was performed. When subsequent blocks of data are added (still using
+    50% overlap), the errors introduced by the transform cancels out.
+    Thanks to the overlapping feature, the MDCT is very useful for
+    quantization. It effectively removes the otherwise easily detectable
+    blocking artifact between transform blocks.
+    N = length of input vector X
+    X = vector of length N/2, will hold fixed point DCT
+    k = 0:1:N-1
+
+                        N-1
+            X(m) =  2   SUM   x(k)*cos(pi/(2*N)*(2*k+1+N/2)*(2*m+1))
+                        k=0
+
+
+    The window that completes the TDAC is applied before calling this function.
+    The MDCT can be calculated using an FFT, for this, the MDCT needs to be
+    rewritten as an odd-time odd-frequency discrete Fourier transform. Thus,
+    the MDCT can be calculated using only one n/4 point FFT and some pre and
+    post-rotation of the sample points.
+
+    Computation of the MDCT implies computing
+
+        x  = ( y   - y        ) + j( y       +  y       )
+         n      2n    N/2-1-2n        N-1-2n     N/2+2n
+
+    using the Fast discrete cosine transform as described in [2]
+
+    where x(n) is an input with N points

+                                      ------------- DCT
+
+    By considering the N/2 overlap, a relation between successive input blocks
+    is found:
+
+        x   (2n) = x (N/2 + 2n)
+         m+1        m

+ REQUIREMENTS

+ REVISION HISTORY
+
+ Description:  Eliminated pointer dependency ( pData_1) on Buffer address.
+               Modified for-loop to countdown loops.
+
+ Description:  No shift information going in/out from fft_rx4_long.
+
+ Description:
+            (1) Increased precision on the radix 2 fft coeff. (from Q10 to Q12)
+            (2) Increased precision on the input (from 0.5 to 1.0).
+            (3) Eliminated hardly used condition (exp = 0).
+            (4) Change interface to fft_rx4_long, so now the same function is
+                used for forward and inverse calculations.
+
+ Description:  per code review comments, eliminated unnecessary headers

+ FUNCTION DESCRIPTION
+
+ This module applies the formula for M/S coding to one grouped scalefactor
+ band.  The ISO code has a similar function which applies M/S coding to an
+ entire frame.
+
+ It is the calling function's responsibility to check the map_mask array, which
+ is filled by the function getmask.  If a scalefactor band is identified as
+ using M/S stereo, the coefficients in that array are calculated using
+ the following formula...
+
+ TempLeft = LeftCoefficient;
+
+ LeftCoefficient  = LeftCoefficient  + RightCoefficient;
+ RightCoefficient = TempLeft         - RightCoefficient;
+
+ This function should be inlined if the compiler supports C99 inlining,
+ as this short function is only called by sfb_tools_ms().
+ Therefore, inlining will not increase the code size.

+ FUNCTION DESCRIPTION
+
+ This function derives noise from the left channel.  The PNS tool is assumed
+ to have been used on the same scalefactor band on the left channel.  The
+ noise on the left/right channels are not necessarily of the same amplitude,
+ and therefore have separate scalefactors.  The noise is thus scaled by the
+ difference between the two transmitted scalefactors.  This scaling is done
+ in fixed-point using a constant 4-element table.

+ FUNCTION DESCRIPTION
+
+ This function steps through all of the scalefactor bands, looking for
+ either PNS or IS to be enabled on the right channel.
+
+ If the codebook used is >= NOISE_HCB, the code then checks for the use
+ of Huffman codebooks NOISE_HCB, INTENSITY_HCB, or INTENSITY_HCB2.
+
+ When a SFB utilizing the codebook NOISE_HCB is detected, a check is made to
+ see if M/S has also been enabled for that SFB.
+
+ If M/S is not enabled, the band's spectral information is filled with
+ scaled random data.   The scaled random data is generated by the function
+ gen_rand_vector.  This is done across all windows in the group.
+
+ If M/S is enabled, the band's spectral information is derived from the data
+ residing in the same band on the left channel.  The information on the right
+ channel has independent scaling, so this is a bit more involved than a
+ direct copy of the information on the left channel.  This is done by calling
+ the inline function pns_corr().
+
+ When a SFB utilizing an intensity codebook is detected, the band's spectral
+ information is generated from the information on the left channel.
+ This is done across all windows in the group.  M/S being enabled has the
+ effect of reversing the sign of the data on the right channel.  This code
+ resides in the inline function intensity_right().

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Brought code in-line with PV standards.
+               Merged PNS and Intensity blocks into one function.
+               Modified routine to interface with a fixed-point implementation.
+               Modified variable names for clarity.
+               Improved for-loop structure that was previously checking
+               the codebook used in each scale factor band multiple times.
+
+ Description:  Added some comments for clarity.
+
+ Description:  Changed strategy for q-format.  Q-format for SFBs should not
+ be grouped.
+
+ Description: Function had to be modified to obey new interpretation of the
+ sfb_prediction_used flag.  LTP takes precedence, and PNS should not be
+ executed when a collision occurs between these two tools.
+
+ Description:
+ (1) Added flag "ltp_data_present"
+ (2) Where feasible, I updated the code to resemble right_ch_sfb_tools_ms.c
+     Just for conformance, readability.
+
+ Description: Added include file - "e_huffmanconst.h"
+
+ Description: The same "Factors" pointer indexing problem that existed in
+ right_ch_sfb_tools_ms also existed here in pns_left.c
+
+ Description:  Modified how groups and windows are handled, as the multigroup
+ case was not correct

+ When a SFB utilizing NOISE_HCB is detected, the band in every window in the
+ group has its spectral information filled with scaled random data.
+
+ The scaled random data is generated by the function gen_rand_vector.
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This module shall replace bands that were encoded with the Huffman codebook
+ NOISE_HCB with random noise as returned from gen_rand_vector().  The result
+ shall be perceptually indistinguishable from the result obtained by the
+ ISO decoder.

+ FUNCTION DESCRIPTION
+
+    Does Hybrid analysis:
+
+        Get higher frequency resolution in the lower QMF subbands
+        creating sub-subbands. This is done by low frequency filtering.
+        Lower QMF subbands are further split in order to obtain a higher
+        frequency resolution, enabling a proper stereo analysis and synthesis
+        for the lower frequencies.
+        Two hybrid are defined. Both filters have length 13 and a delay of 6.
+        In this implementation, the symmetry of the filters helps to simplify
+        the design.
+
+
+   Increase Freq. Resolution

+
+                      Variable is named (pLongFrameInfo) because this function
+                      is only used for LONG windows.

+ FUNCTION DESCRIPTION
+
+ This function adds pulses to defined ranges of coefficients in the window,
+ for the case of LONG windows.  The pulses are unsigned, so
+ negative coefficients subtract the pulse, and positive coefficients add it.
+ (The ampltiude of the coefficient is always increased by the pulse)
+
+ A maximum of 4 coefficients may be modified by a pulse, and these
+ coefficients must all occur in the same scalefactor band.
+
+ The number of pulse-encoded coefficients to be processed by this function
+ is communicated to this function via pPulseInfo->number_pulse
+
+ This value is equal to the actual number of pulses - 1.
+ (e.g if pPulseInfo->number_pulse == 0, one pulse is assumed)
+ This function must not be called if no pulse encoded data exists.
+ The function assumes that at least one pulse exists.
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This module shall correctly add transmitted pulse(s) to the correct
+ coefficients in a LONG window.

+ Description:
+        1. Modified ifndef STD_TYPE_DEFS_H with

+        2. Merged cai if-def structures and C++ definition
+            3. Updated copyright notice

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    pExt = pointer to the external interface structure. See the file
+           PVMP4AudioDecoder_API.h for a description of each field.
+           Data type of pointer to a tPVMP4AudioDecoderExternal
+           structure.
+
+           pExt->pInputBuffer: pointer to input buffer containing input
+                               bitstream
+
+           pExt->inputBufferCurrentLength: number of bytes in the input buffer

+                                pExt->inputBufferUsedLength
+
+    pMem = void pointer to hide the internal implementation of the library
+           It is cast back to a tDec_Int_File structure. This structure
+           contains information that needs to persist between calls to
+           this function, or is too big to be placed on the stack, even
+           though the data is only needed during execution of this function
+           Data type void pointer, internally pointer to a tDec_Int_File

+
+ Local Stores/Buffers/Pointers Needed: None
+           (The memory set aside in pMem performs this task)
+
+ Global Stores/Buffers/Pointers Needed: None
+
+ Outputs:
+     status = 0                       if no error occurred
+              MP4AUDEC_NONRECOVERABLE if a non-recoverable error occurred
+              MP4AUDEC_RECOVERABLE    if a recoverable error occurred.
+              Presently a recoverable error does not exist, but this
+              was a requirement.
+
+
+ Pointers and Buffers Modified:
+    pMem contents are modified.
+    pExt: (more detail in the file PVMP4AudioDecoder_API.h)
+    inputBufferUsedLength - number of array elements used up by the stream.
+    remainderBits - remaining bits in the next UInt32 buffer
+    samplingRate - sampling rate in samples per sec
+    encodedChannels - channels found on the file (informative)
+    frameLength - length of the frame

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Pulled in loop structure from console.c, so that this function
+               now decodes all frames in the file.
+
+               Original program used several global variables.  These have been
+               eliminated, except for situations in which the global variables
+               could be converted into const types.  Otherwise, they are passed
+               by reference through the functions.
+
+ Description:  Begin mods for file I/O removal
+
+ Description:  Merged trans4m_freq_2_time, trans4m_time_2_freq, etc.
+
+ Description:  Removing commented out sections of code.  This includes the
+               removal of unneeded functions init_lt_pred, reset_mc_info,
+
+ Description: Copied from aac_decode_frame.c and renamed file,
+              Made many changes.
+
+ Description: Prepare for code review
+
+ Description: Update per review comments:
+              1) Add comment about leaveGetLoop
+              2) Remove inverseTNSCoef array
+              3) fix wnd_shape_this_bk to wnd_shape_prev_bk in F to T
+              4) Clean up comments
+              5) Change call to long_term_synthesis
+
+ Description: Remove division for calculation of bitrate.
+
+ Description: Remove update of LTP buffers if not LTP audio object type.
+
+ Description: Add hasmask to call to right_ch_sfb_tools_ms
+
+ Description:
+ Modified to call ltp related routines on the left channel
+ before intensity is called on the right channel.  The previous version
+ was causing a problem when IS was used on the right channel and LTP
+ on the left channel for the same scalefactor band.
+
+ This fix required creating a new function, apply_ms_synt, deleting another
+ function (right_ch_sfb_tools_noms.c), and modifying the calling order of
+ the other functions.
+
+ Description: Made changes per review comments.
+
+ Description: Changed name of right_ch_sfb_tools_ms to pns_intensity_right
+
+ Description: Added cast, since pVars->inputStream.usedBits is UInt, and
+ pExt->remainderBits is Int.
+
+ pExt->remainderBits =
+    (Int)(pVars->inputStream.usedBits & INBUF_BIT_MODULO_MASK);
+
+ Description: Modified to pass a pointer to scratch memory into
+ tns_setup_filter.c
+
+ Description: Removed include of "s_TNSInfo.h"
+
+ Description: Removed call to "tns_setup_filter" which has been eliminated
+ by merging its functionality into "get_tns"
+
+ Description:  Passing in a pointer to a q-format array, rather than
+ the address of a single q-format, for the inverse filter case for
+ apply_tns.
+
+ Description:
+ (1) Added #include of "e_ElementId.h"
+     Previously, this function was relying on another include file
+     to include "e_ElementId.h"
+
+ (2) Updated the copyright header.
+
+ Description:
+ Per review comments, declared two temporary variables
+
+    pChLeftShare  = pChVars[LEFT]->pShareWfxpCoef;
+    pChRightShare = pChVars[RIGHT]->pShareWfxpCoef;
+
+ Description:
+    long_term_synthesis should have been invoked with max_sfb
+    as the 2nd parameter, rather than pFrameInfo->sfb_per_win[0].
+
+    Old
+                long_term_synthesis(
+                    pChVars[ch]->wnd,
+                    pFrameInfo->sfb_per_win[0] ...
+
+    Correction
+                long_term_synthesis(
+                    pChVars[ch]->wnd,
+                    pChVars[ch]->pShareWfxpCoef->max_sfb ...
+
+    This problem caused long_term_synthesis to read memory which
+    was not initialized in get_ics_info.c
+
+ Description:
+ (1) Utilize scratch memory for the scratch Prog_Config.
+
+ Description: (1) Modified to decode ID_END syntactic element after header
+
+ Description:
+ (1) Reconfigured LTP buffer as a circular buffer.  This saves
+     2048 Int16->Int16 copies per frame.
+
+ Description: Updated so ltp buffers are not used as a wasteful
+ intermediate buffer for LC streams.  Data is transferred directly
+ from the filterbank to the output stream.
+
+ Description: Decode ADIF header if frame count is zero.
+              The AudioSpecificConfig is decoded by a separate API.
+
+ Description: Added comments explaining how the ltp_buffer_state
+ variable is updated.
+
+
+ Description: Modified code to take advantage of new trans4m_freq_2_time_fxp,
+ which writes the output directly into a 16-bit output buffer.  This
+ improvement allows faster operation by reducing the amount of memory
+ transfers.  Speed can be further improved on most platforms via use of a
+ DMA transfer in the function write_output.c
+
+ Description: perChan[] is an array of structures in tDec_Int_File. Made
+              corresponding changes.
+
+ Description: Included changes in interface for q_normalize() and
+              trans4m_freq_2_time_fxp.
+
+ Description: Included changes in interface for long_term_prediction.
+
+ Description: Added support for DSE (Data Streaming Channel). Added
+              function get_dse() and included file get_dse.h
+
+ Description: Added support for the ill-case when a raw data block contains
+              only a terminator <ID_END>. This is illegal but is added
+              for convinience
+
+ Description: Added support for empty audio frames, such the one containing
+              only DSE or FILL elements. A trap was added to stop processing
+              when no audio information was sent.
+
+ Description: Added support for adts format files. Added saturation to
+              floating point version of aac+ decoding
+
+ Description:

+
+   pMem =  pointer to allocated memory, of the size returned by the function
+           PVMP4AudioDecoderGetMemRequirements. This is a void pointer for
+           two reasons:
+           1) So the external program does not need all of the header files
+              for all of the fields in the structure tDec_Int_File
+           2) To hide data and the implementation of the program. Even knowing

+ Inputs:

+           and output information. Look in PVMP4AudioDecoder_API.h for all the
+           fields to this structure. Data type pointer to a
+           tPVMP4AudioDecoderExternal structure.
+
+   pMem =  pointer to allocated memory, of the size returned by the function
+           PVMP4AudioDecoderGetMemRequirements. This is a void pointer for
+           two reasons:
+           1) So the external program does not need all of the header files
+              for all of the fields in the structure tDec_Int_File
+           2) To hide data and the implementation of the program. Even knowing

+ FUNCTION DESCRIPTION
+
+  This function is called when the same audio clip will be played again from
+  the begining. This situation happens when the "stop" button is pressed or
+  the "loop-mode" is selected on PVPlayer. Since it is the same audio clip to
+  be played again, the decoder does not need to reset the audioSpecificInfo.
+  However, the overlap-and-add buffer of the filterbank output needs to be
+  cleared, so that the decoder can re-start properly from the begining of
+  the audio. The frame number counter, pVars->bno, is set to 1 because the
+  audioSpecificInfo is decoded on pVars->bno==0

+ Description:
+
+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    pExt = pointer to the external interface structure. See the file
+           PVMP4AudioDecoder_API.h for a description of each field.
+           Data type of pointer to a tPVMP4AudioDecoderExternal
+           structure.
+
+           pExt->pInputBuffer: pointer to input buffer containing input
+                               bitstream
+
+           pExt->inputBufferCurrentLength: number of bytes in the input buffer
+
+           pExt->inputBufferUsedLength: number of bytes already consumed in
+                                        input buffer
+
+           pExt->remainderBits: number of bits consumed in addition to
+                                pExt->inputBufferUsedLength
+
+    pMem = void pointer to hide the internal implementation of the library
+           It is cast back to a tDec_Int_File structure. This structure
+           contains information that needs to persist between calls to
+           this function, or is too big to be placed on the stack, even
+           though the data is only needed during execution of this function
+           Data type void pointer, internally pointer to a tDec_Int_File
+           structure.
+
+ Local Stores/Buffers/Pointers Needed: None
+           (The memory set aside in pMem performs this task)
+
+ Global Stores/Buffers/Pointers Needed: None
+
+ Outputs:
+     status = 0                       if no error occurred
+              MP4AUDEC_NONRECOVERABLE if a non-recoverable error occurred
+              MP4AUDEC_RECOVERABLE    if a recoverable error occurred.
+              Presently a recoverable error does not exist, but this
+              was a requirement.
+
+
+ Pointers and Buffers Modified:
+    pMem contents are modified.
+    pExt: (more detail in the file PVMP4AudioDecoder_API.h)
+    inputBufferUsedLength - number of array elements used up by the stream.
+    remainderBits - remaining bits in the next UInt32 buffer
+    samplingRate - sampling rate in samples per sec
+    encodedChannels - channels found on the file (informative)
+    frameLength - length of the frame
+
+ Local Stores Modified: None.
+
+ Global Stores Modified: None.

+ FUNCTION DESCRIPTION
+
+ This module first scans every scalefactor band for the frame, insuring that
+ at least one element in that scalefactor band is using all available bits.
+ If not, the elements in the scalefactor band are shifted up to use all 31
+ data bits.  The q-format is adjusted accordingly.
+
+ This module then scans the q-formats for each scalefactor band.
+ Upon finding the minimum q-format in the frame, the coefficients in each
+ scalefactor band are normalized to the minimum q-format.
+ The minimum q-format is then returned to the calling function, which is now
+ the q-format for the entire frame.

+ Description: Moved large ltp_buffer up to s_tDec_Int_Chan.h, since this
+ move allowed for other elements in this structure to be shared with

+
+ Description: Decreased size of LTP buffers from 4096 to 3072.  The upper 1024

+ 4 kilobytes in memory.
+
+ Description: Decreased size of LTP buffers again from 3072 to 2048.  This
+ time, I realized that 1024 elements were duplicated in the 32-bit array
+ pVars->pChVars[]->time_quant.  Rather than copy this data EVERY frame
+ from a 32-bit to a 16-bit LTP buffer, the data is accessed only

+
+ Description:
+ (1) Modified to include the lines...

+
+    #ifdef __cplusplus

+    #endif
+

+
+ Description:
+ (1) Changed hard coded size of arrays from "8" to "TNS_MAX_WIN"
+ (2) Moved elements from s_TNSinfo.h up to the level of TNS_frame_info
+ (3) Added Bool "tns_data_present" for future use.
+ (4) Moved lpc_coef up from s_TNSfilt.h (allowed for use of smaller array.)
+
+ Description:
+ (1) Removed the array "coef_res", which is now a local variable on the

+ REVISION HISTORY
+
+ Description: Added lpc, start, & size, so the data from
+ tns_inv_subblock can be shared with tns_decode_subblock.
+
+ Description: Removed lpc to save 2KB of memory (on 32-bit machines.)
+ This change requires tns_decode_coef.c to perform calculations in place.
+
+ Description: Removed start & size.  start_band and stop_band can simply
+ take on a new meaning after this function.  (coef index, rather than
+ scalefactor band index.)
+
+ Description: Had to add "start_coef" and "stop_coef" in order to preserve
+ values "start_band" and "stop_band."  This required a change to
+ tns_setup_filter.c also.
+
+ Description: Had to add element "q_lpc" to store the q-format of the lpc
+ coefficients passed via "coef."
+
+ Description: Moved lpc_coef array up to the s_TNS_frame_info.h structure.

+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Implemented 24-bit fixed point version
+               Optimized C code
+
+ Description:
+            - Added OVERFLOW_SHIFT_DOWN to avoid overflow.
+            - Increased precision by using the Q format of the LPC coefficient.
+            - Modified interface to add LPC Q format and scratch memory
+              for the state variables.
+            - Added pv_memset to clear state filter
+            - Updated format for comments (to PV standard)
+            - Updated copyright notice
+
+ Description:
+            - Changed multiplication scheme to increase precision. This
+              works better than older version.
+
+ Description:
+            - Include log2(order) as a scaling down parameter.
+
+ Description:
+            Modified to reflect code review comments
+                - misspelled words, extra comments and explicit requirements
+
+ Description:
+            deleted comment about fix Q format (L 107)
+
+ Description:  Implemented a more efficient version, which eliminated the use
+ of "scratch memory" via introducing a pointer that references the actual
+ output.
+
+ Description: Removed the parameter "scratch_Int32_buffer" as this space
+ in memory is no longer needed by this function.
+
+ Description: Removed references to "scratch_Int32_buffer" in the Inputs
+ section.
+
+ Description:
+    Modified casting to ensure proper operations for different platforms
+
+ Description:
+    Per code review comment:
+    Eliminated casting to UInt and Int in b_low and b_high, they are
+    redundant and may add unncessary extra cycles in some platforms
+
+ Description: Updated the SW template to include the full pathname to the
+ source file and a slightly modified copyright header.
+
+ Description: Changed the order of the unsigned * signed multiply so the
+ casting to Int32 is performed on the unsigned operand.
+
+ Description:
+    Modified 32 by 16 bit multiplications to avoid unnecessary moves to
+    registers. Also split the code (based on flag direction) to simplify
+    pointer's updates
+
+ Description:

+ FUNCTION DESCRIPTION
+
+    A block of spectral data (Int32 spec[]) of length (const Int spec_length)
+    is processed by a simple all-pole filter defined by
+    LPC coefficients passed via (const Int lpc[])
+
+    TNS filter equation
+        y(n) =  x(n) - lpc(2)*y(n-1) - ... - lpc(order+1)*y(n-order)
+
+    The filter calculation is performed in place, i.e. the output is passed
+    back to the calling function via (Int32 spec[])
+
+    The filter's order is defined by the variable (const Int order)
+    The direction of the filter's application is defined by (const Int inc)
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    This function should match the functionality of the ISO code.
+    The implementation does support filter orders bigger or equal to 1.
+    The size of the spectral coeffcients has to be bigger or equal than 1.

+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Implemented in 16-bit Fixed Point
+
+ Description:  Implemented in 24-bit Fixed Point
+
+ Description:  Modified to return the calculated LPC coefficients "in place"
+ This saves memory, cycles, etc. because it saves a large temporary
+ array being declared on the stack in another function (tns_setup_filter)
+
+ Description:  Modified to return the q-format of the lpc coefficients.
+
+ Description:  Modified for more reliable overflow protection.  tns_decode_coef
+ no longer relies on "reasonable" outputs.  This code should handle all
+ possible inputs.
+
+ Description:  Modified per review comments.
+
+ Description:  Added check condition to avoid numbers with a Q bigger than
+        15 from being passed, otherwise in a 16-bit number the sign is lost.
+
+ Description:  Modified to utilize scratch memory techniques, thereby
+ eliminating two arrays of size TNS_MAX_ORDER, which were previously declared
+ on the stack.
+
+ Description: Updated the SW template to include the full pathname to the
+ source file and a slightly modified copyright header.
+
+ Description:
+ (1) Changed the order of the unsigned * signed multiply so the
+     casting to Int32 is performed on the unsigned operand.
+
+ (2) Removed some unnecessary casting.
+ (3) Fixed a problem where a 16-bit value was casted to 32-bits AFTER
+     a shift.  It should have been cast to 32-bits BEFORE the shifting.
+
+
+ Description:  modified precision of coefficients

+ FUNCTION DESCRIPTION
+
+    A block of spectral data (Int32 coef[]) of length (const Int num_coef)
+    is processed by a simple all-zero filter defined by
+    LPC coefficients passed via (const Int lpc[])
+
+    TNS filter equation
+        y(n) =  x(n) + lpc(2)*x(n-1) + ... + lpc(order+1)*x(n-order)
+
+    The filter calculation is performed in place, i.e. the output is passed
+    back to the calling function via (Int32 coef[])
+
+    In order to avoid overflow, the filter input (Int32 coef[]) must utilize
+    only the lower 16-bits.  The upper 16-bits must be available.
+
+    The filter's order is defined by the variable (const Int order)
+
+    The direction of the filter's application is defined by
+    (const Int direction)
+
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+    [Int32 coef] must store no more than 16 bits of data.
+
+    This is required to utilize methods that do not change the q-format of
+    the input data [Int32 coef], and to make use of a fast
+    16 x 16 bit multiply.
+
+    This function should not be called for order <= 0.
+
+    This function must not be called with lpc_qformat < 5

+ REVISION HISTORY
+
+ Description:
+    changed to decrement loop
+    change wnd_shape from structure to passing parameters
+    modified window tables from UInt to UInt16 to assure proper operation
+    without dubious typecast
+    changed logic to hit most common states first.
+    modified Time_data from Int to Int32 to hold
+    possible overflow before saturation process.
+
+ Description:
+    Increase processing on some loop by using more pointers
+    changed interface to avoid passing a pointer for wnd_shape_prev_bk, this
+    element is not change in this function because of this function use
+    in the LTP module
+
+ Description:
+    Added rounding to multiplication
+
+ Description:
+    Update input description and eliminate unneeded comments
+
+ Description:
+    LONG_START_WINDOW was using SHORT_WINDOW instead of
+    HALF_SHORT_WINDOW, causing a for loop to exceed its count
+
+ Description:
+    Modified structure of code so exp is not tested before it
+    is initialized.  Also, new structure avoids double-testing
+    of exp_freq = ALL_ZEROS_BUFFER.
+
+ Description:
+    The result of a shift is undefined if the right operand is greater than
+    or equal to the number of bits in the left expression's type
+    To avoid undefined shift by 32, a check of the shift has been
+    added, so the function proceeds only when the exponent is less
+    than 32. By design the shift up is related to the global gain,
+    and controlled by the encoder, so saturation is not allowed.
+    In both short and long window, processing is skip if an all zero
+    input buffer or excessive down shift is detected.
+
+ Description:
+    Changes according to code review comments. Also, modified if-else
+    structure so the imdct_fxp is not called with an all zero input buffer
+
+ Description:
+    Replaced function buffer_normalization by buffer_adaptation, to ease
+    use of 16 bits. Function buffer_normalization becomes  obsolete.
+
+ Description:
+    Modified call to imdct_fxp to reflect extended precision use. Added
+    routine buffer_adaptation to extract 16 MSB and keep highest.
+    precision. Modify casting to ensure proper operations for different
+    platforms
+
+ Description:
+    Eliminate double access to memory by loading data directly to the
+    time array. Also reduced cycle count and added precision by combining
+    downshifting in only one operation. Added adaptive rounding factor.
+    Change exponent threshold when operations are waived. It is use to be 32
+    but by combining downshifting, this new threshold is now 16. This may
+    avoid unneeded calculations for extremely small numbers.
+
+ Description:
+    Per review comments:
+        - Added comments to clarify buffer_adaptation function
+        - Deleted  reference to include file "buffer_normalization.h"
+        - Modified IF-ELSE so long_windows case is considered first
+        - Eliminated extra IF when computing the rounding, so when exp ==0
+          less cycles are used shifting than in an extra if-else
+        - Corrected negative shift when computing rounding factor
+        - Added condition when exp > 16 (for long windows)
+
+ Description:
+    Modified IF-ELSE structure so now ALL_ZEROS_BUFFER condition is share
+    with exp > 16 condition. This avoid code duplication for both cases.
+
+ Description:
+        - Modified function interface to add output_buffer
+        - Eliminated the 32 bit version of the current output, calculations
+          are placed directly in output_buffer. In this way the buffer
+          Time_data needs only to be 1024 Int32, instead of 2048 (per channel).
+          Also, added the limit macro inside the function (this reduces access
+          to memory).
+        - Updated Pseudo - Code

+ FUNCTION DESCRIPTION
+
+The time/frequency representation of the signal is mapped onto the time
+domain by feeding it into the filterbank module. This module consists of
+an inverse modified discrete cosine transform (IMDCT), and a window and an
+overlap-add function. In order to adapt the time/frequency resolution of the
+filterbank to the characteristics of the input signal, a block switching tool
+is also adopted. N represents the window length, where N is a function of the
+window_sequence. For each channel, the N/2 time-frequency values are
+transformed into the N time domain values via the IMDCT. After applying the
+window function, for each channel, the first half of the sequence is added to
+the second half of the previous block windowed sequence to reconstruct the
+output samples for each channel outi,n.
+
+The adaptation of the time-frequency resolution of the filterbank to the
+characteristics of the input signal is done by shifting between transforms
+whose input lengths are either 2048 or 256 samples. By enabling the block
+switching tool, the following transitions are meaningful:
+
+from ONLY_LONG_SEQUENCE to   { LONG_START_SEQUENCE
+                               ONLY_LONG_SEQUENCE
+
+from LONG_START_SEQUENCE to  { LONG_STOP_SEQUENCE
+                               EIGHT_SHORT_SEQUENCE
+
+from LONG_STOP_SEQUENCE to   { LONG_START_SEQUENCE
+                               ONLY_LONG_SEQUENCE
+
+from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE
+                               EIGHT_SHORT_SEQUENCE
+
+Window shape decisions are made by the encoder on a frame-by-frame-basis.
+The window selected is applicable to the second half of the window function
+only, since the first half is constrained to use the appropriate window
+shape from the preceding frame.
+The 2048 time-domain values x'(i)(n), (i window, n sample) to be windowed are
+the last 1024 values of the previous window_sequence concatenated with 1024
+values of the current block. The formula below shows this fact:
+
+                     |  x(i-1)(n+1024)      for    0 < n < 1024
+            x'(i)(n) {
+                     |  x(i)(n)             for 1024 < n < 2048
+
+
+Buffer Time_data data from previous Frequency to Time conversion, used
+for overlap and add
+
+Once the window shape is selected, the window_shape syntax element is
+initialized. Together with the chosen window_sequence all information needed
+for windowing exist.
+With the window halves described below all window_sequences can be assembled.
+For window_shape == 1, the window coefficients are given by the Kaiser -
+Bessel derived (KBD) window.
+Otherwise, for window_shape == 0, a sine window is employed.
+
+The window length N can be 2048 or 256 for the KBD and the sine window.
+All four window_sequences explained below have a total length of 2048
+samples.
+For all kinds of window_sequences the window_shape of the left half of
+the first transform window is determined by the window shape of the previous
+block.
+
+In the case of EIGHT_SHORT_SEQUENCE the processing is done in-place and
+in descendent order to avoid using extra memory.
+The ordering is as follows:
+
+                                            Pn: Previous data for window n
+                                            Cn:  Current data for window n
+
+
+                                                128 freq.

+ REVISION HISTORY
+
+ Description:
+        Modified normalization, so it now happen per window basis, eliminated
+        shifts left or rigth to accomodate TNS inverse filtering. The output
+        is 32 bits but only the lowest 16 are being used.
+        Modified fuction interface
+
+ Description: Modified variable names with leading "p" for pointers
+
+ Description:
+        Modified call to mdct_fxp to reflect extended precision use. Added routine
+        buffer_adaptation to extract 16 MSB and keep highest precision.
+        Modify casting to ensure proper operations for different platforms
+
+ Description:
+        Added comments according to code review
+
+ Description:
+        Removed include file "buffer_normalization.h"
+
+ Description:
+        Eliminated buffer_adaptation() and embedded its functionality in other
+        functions. Commented out the short window section given that this is
+        not supported by the standards
+
+ Description:
+        Added shift down operation for case when the window was equal to one.
+        This was not needed previuosly because buffer_adaptation() was doing
+        it.
+
+ Description: Created local version of vectors Long_Window_fxp and
+              Short_Window_fxp. This solve linking problem when using the
+              /ropi option (Read-only position independent) for some
+              compilers.

+ FUNCTION DESCRIPTION
+
+The time/frequency representation of the signal is mapped onto the frequency
+domain by feeding it into the filterbank module. This module consists of
+a modified discrete cosine transform (MDCT), (windowing and DCT).
+In order to adapt the time/frequency resolution of the filterbank to the
+ characteristics of the input signal, a block switching tool is also
+adopted. N represents the window length, where N is a function of the
+window_sequence. For each channel, the N time values are transformed into the
+N/2 frequency domain values via the MDCT.
+
+The adaptation of the time-frequency resolution of the filterbank to the
+characteristics of the input signal is done by shifting between transforms
+whose input lengths are either 2048 or 256 samples. By enabling the block
+switching tool, the following transitions are meaningful:
+
+from ONLY_LONG_SEQUENCE to   { LONG_START_SEQUENCE
+                               ONLY_LONG_SEQUENCE
+
+from LONG_START_SEQUENCE to  { LONG_STOP_SEQUENCE
+                               EIGHT_SHORT_SEQUENCE
+
+from LONG_STOP_SEQUENCE to   { LONG_START_SEQUENCE
+                               ONLY_LONG_SEQUENCE
+
+from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE
+                               EIGHT_SHORT_SEQUENCE
+
+Window shape decisions are made by the encoder on a frame-by-frame-basis.
+The window selected is applicable to the second half of the window function
+only, since the first half is constrained to use the appropriate window
+shape from the preceding frame.
+The 2048 time-domain values x'(i)(n), (i window, n sample) to be windowed are
+the last 1024 values of the previous window_sequence concatenated with 1024
+values of the current block. The formula below shows this fact:
+
+                     |  x(i-1)(n+1024)      for    0 < n < 1024
+            x'(i)(n) {
+                     |  x(i)(n)             for 1024 < n < 2048
+
+
+
+Once the window shape is selected, the window_shape syntax element is
+initialized. Together with the chosen window_sequence all information needed
+for windowing exist.
+With the window halves described below all window_sequences can be assembled.
+For window_shape == 1, the window coefficients are given by the Kaiser -
+Bessel derived (KBD) window.
+Otherwise, for window_shape == 0, a sine window is employed.
+
+The window length N can be 2048 or 256 for the KBD and the sine window.
+All four window_sequences explained below have a total length of 2048
+samples.
+For all kinds of window_sequences the window_shape of the left half of
+the first transform window is determined by the window shape of the previous
+block.

+
+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description:  Modified from original shareware code
+
+ Description:  Eliminated 3 divisions and 1 multiplication through a table
+ look-up method for calculating 1/mod and constant allocation of 1/mod^3
+ and 1/mod^2.
+ Eliminated 3 additions through simple optimizations in the code.
+ Changed if/else  statement to a switch/case utilizing fall-through.
+
+ Description:   Made changes per review comments.  Main improvements were
+ in change of switch/case to if statement, and use of temporary variable
+ to hold value of *pQuantSpec.
+
+ Description: (1) Typecast codeword_indx to Int32 before multiplication, this
+              assures the shift operation happens on a 32-bit product on
+              TI-C55x processor.
+              (2) define temp_spec as Int32 to avoid overflow
+
+ Description: Modified per review comments
+              (1) remove the two typecastings of codeword_indx when
+                  pHuffCodebook->dim == DIMENSION_4
+              (2) temp_spec is Int because the result never exceeds 16 bits
+
+ Description: Break up and combine unpack index with sign bit reading and for
+              special escape code. Parent function must know which one of the
+              3 functions should be called.
+
+ Description: Put back if-statement to get the max.
+
+ Description: When searching for the max, there was some instances where the
+              max was compared against a negative number, so the max was never
+              updated (defaulted to 0), leading to block processing in other
+              magnitude sensitive stages.

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+          Int  quant_spec[]  = Array for storage of the quantized
+                               spectral coefficients.  Length is either 2 or 4.
+                               See Ref #1, Page 76 for a complete description.
+
+          Int  codeword_indx = The index into the Huffman table.
+                               Range is [1-288]
+
+    const Hcb *pHuffCodebook = Pointer to HuffmanCodebook information.
+
+          BITS  *pInputStream = Pointer to the bitstream buffer.
+          Int *max           = Pointer to maximum coefficient value.
+
+ Local Stores/Buffers/Pointers Needed:
+    const UInt div_mod[18]   = An array with the values for 1/mod
+                               stored in Q-formats 13.
+
+ Global Stores/Buffers/Pointers Needed:
+    None
+
+ Outputs:
+    None
+
+ Pointers and Buffers Modified:
+    Int quant_spec[] = Output (the quantized and signed spectral coefficients)
+                       returned via this pointer.
+
+ Local Stores Modified:
+    None
+
+ Global Stores Modified:

+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function decodes quantized spectral coefficients and decode their signs
+ from the input bitstream. Quantized spectral coefficients are transmitted as
+ four-tuples or 2-tuples, and this information is conveyed to the function via
+ the variable HuffCodebook->dim.
+
+ See Reference #1 for a complete description
+------------------------------------------------------------------------------
+ REQUIREMENTS
+
+ This function shall correctly calculate pQuantSpec[], given the inputs
+
+ codeword_indx     = {1-288};
+ HuffCodebook->off = {0, 1, 4};
+ HuffCodebook->mod = {3, 8, 9, 13, 17};
+
+ mod =   LAV + 1 if unsigned codebook
+ mod = 2*LAV + 1 if   signed codebook
+
+ Range of values for LAV is {2,7,12,16} if unsigned
+                            {1,4}       if   signed
+
+ Additionally,
+     LAV <= 2 if dim == 4
+
+ This restricts mod ==  3                if dim == 4
+            and mod == {3, 8, 9, 13, 17} if dim == 2
+
+ This function will NOT function correctly if fed values that do not
+ meet the requirements as stated above.
+
+ This limitation on the range of values was determined by analysis
+ of Reference #1 (see below.)

+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Finished first pass of optimization.
+
+ Description: Made changes based on review comments.
+
+ Description: Made input to Chebps_Wrapper consistent with that of Chebps.
+
+ Description: Replaced current Pseudo-code with the UMTS code version 3.2.0.

+
+ Description: Replaced basic_op.h and oper_32b.h with the header files of the
+              math functions used by the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Used "-" operator instead of calling sub function in the
+                 az_lsp() code.
+              2. Copied detailed function description of az_lsp from the
+                 header file.
+              3. Modified local variable definition to one per line.
+              4. Used NC in the definition of f1 and f2 arrays.
+              5. Added curly brackets in the IF statement.
+
+ Description: Changed function interface to pass in a pointer to overflow
+              flag into the function instead of using a global flag. Removed
+              inclusion of unneeded header files.
+
+ Description:  For Chebps() and Az_lsp()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation.
+              4. Eliminated not needed variables
+              5. Eliminated if-else checks for saturation
+              6. Deleted unused function cheps_wraper

+ FUNCTION NAME: Az_lsp
+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS FOR Az_lsp
+
+ Inputs:
+    a = predictor coefficients (Word16)
+    lsp = line spectral pairs (Word16)
+    old_lsp = old line spectral pairs (Word16)
+
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    pOverflow -> 1 if the operations in the function resulted in saturation.
+
+ Returns:
+    None.
+
+ Global Variables Used:
+    None.
+
+ Local Variables Needed:
+    None.
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function computes the LSPs from the LP coefficients.
+
+ The sum and difference filters are computed and divided by 1+z^{-1} and
+ 1-z^{-1}, respectively.
+
+     f1[i] = a[i] + a[11-i] - f1[i-1] ;   i=1,...,5
+     f2[i] = a[i] - a[11-i] + f2[i-1] ;   i=1,...,5
+
+ The roots of F1(z) and F2(z) are found using Chebyshev polynomial evaluation.
+ The polynomials are evaluated at 60 points regularly spaced in the
+ frequency domain. The sign change interval is subdivided 4 times to better
+ track the root. The LSPs are found in the cosine domain [1,-1].
+
+ If less than 10 roots are found, the LSPs from the past frame are used.
+

+ REQUIREMENTS
+
+ None.

+ REVISION HISTORY
+
+ Description: Updated template. Changed function interface to pass in a
+              pointer to overflow flag into the function instead of using a
+              global flag. Removed inclusion of unwanted header files. Changed
+              the name of input and output variables for clarity.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Replaced l_extract functionality, code size and speed
+                 do not justify calling this function
+              3. Eliminated sub() function call, replace by (-), this knowing
+                 that the result will not saturate.
+
+ Description:  Added casting to eliminate warnings

+ Inputs:
+    L_num = 32 bit signed integer (Word32) whose value falls in the
+                range : 0x0000 0000 < L_num < L_denom

+               0 < lo < 0x7fff
+
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    pOverflow -> 1 if the 32 bit divide operation resulted in overflow
+
+ Returns:
+    result = 32-bit quotient of of the division of two 32 bit integers
+                L_num / L_denom (Word32)

+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function is a fractional integer division of two 32 bit numbers, the
+ numerator L_num and the denominator L_denom. The denominator is formed by
+ combining denom_hi and denom_lo. Note that denom_hi is a normalized numbers.
+ The numerator and denominator must be positive and the numerator must be
+ less than the denominator.
+
+ The division is done as follows:
+ 1. Find 1/L_denom by first approximating: approx = 1 / denom_hi.
+ 2. 1/L_denom = approx * (2.0 - L_denom * approx ).
+ 3. result = L_num * (1/L_denom).

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description: Per review comments, replaced includes of "basic_op.h"
+ and "count.h" with "shr.h", "sub.h", and "add.h"
+
+ Description:  For Int_lpc_1and3()  and Int_lpc_1and3_2()
+              1. Replaced array addressing by pointers
+              2. Eliminated math operations that unnecessary checked for
+                 saturation
+              3. Unrolled loops to speed up processing
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Put file into template.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Replaced basic_op.h with the header files of the math functions
+              used in the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Defined one local variable per line.
+              2. Used "&=", ">>=", and "+=" in the code.
+
+ Description: Updated template. Changed function interface to pass in a
+              pointer to overflow flag into the function instead of using a
+              global flag.
+
+ Description: Removed inclusion of inv_sqrt.tab file. Changed array name
+              from "table" to "inv_sqrt_tbl"
+
+ Description: Removed math operations that were not needed as functions,
+             this because the numbers themselves will not saturate the
+             operators, so there is not need to check for saturation.
+
+ Description: Updated copyrigth year, according to code review comments.
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations

+ FUNCTION NAME: Inv_sqrt
+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    L_x = input value (Word32)
+    pOverflow = pointer to overflow flag
+
+ Outputs:
+    pOverflow -> if the Inv_sqrt operation resulted in an overflow.
+
+ Returns:
+    L_y = inverse squareroot of L_x (Word32)
+
+ Global Variables Used:
+    None.
+
+ Local Variables Needed:
+    None.
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function computes 1/sqrt(L_x), where L_x is positive.
+ If L_x is negative or zero, the result is 1 (3fff ffff).
+
+ The function 1/sqrt(L_x) is approximated by a table and linear
+ interpolation. The inverse square root is computed using the
+ following steps:
+    1- Normalization of L_x.
+    2- If (30-exponent) is even then shift right once.
+    3- exponent = (30-exponent)/2  +1
+    4- i = bit25-b31 of L_x;  16<=i<=63  because of normalization.
+    5- a = bit10-b24
+    6- i -=16
+    7- L_y = table[i]<<16 - (table[i] - table[i+1]) * a * 2
+    8- L_y >>= exponent

+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    L_x = normalized input value of type Word32
+    exp = number of shifts required to normalize L_x; it is of type Word16
+    exponent = pointer to the integer part of Log2 (of type Word16)
+           whose valid range is: 0 <= value <= 30
+    fraction = pointer to the fractional part of Log2 (of type Word16)
+           whose valid range is: 0 <= value < 1
+
+ Outputs:
+    exponent points to the newly calculated integer part of Log2
+    fraction points to the newly calculated fractional part of Log2
+
+ Returns:
+    None
+
+ Global Variables Used:
+    None
+
+ Local Variables Needed:
+    table = Log2 table of constants of type Word16
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ The function Log2(L_x) calculates the logarithm of the normalized input
+ buffer L_x. The logarithm is approximated by a table and linear
+ interpolation. The following steps are used to compute Log2(L_x):
+
+ 1. exponent = 30 - norm_exponent
+ 2. i = bit25-b31 of L_x;  32<=i<=63  (because of normalization).
+ 3. a = bit10-b24
+ 4. i = i - 32
+ 5. fraction = table[i]<<16 - (table[i] - table[i+1]) * a * 2

+ FUNCTION DESCRIPTION
+
+ This function finds the polynomial F1(z) or F2(z) from the LSPs. If the LSP
+ vector is passed at address 0, F1(z) is computed and if it is passed at
+ address 1, F2(z) is computed.
+
+ This is performed by expanding the product polynomials:
+
+    F1(z) =   product   ( 1 - 2 lsp[i] z^-1 + z^-2 )
+        i=0,2,4,6,8
+    F2(z) =   product   ( 1 - 2 lsp[i] z^-1 + z^-2 )
+        i=1,3,5,7,9
+
+ where lsp[] is the LSP vector in the cosine domain.
+
+ The expansion is performed using the following recursion:
+
+    f[0] = 1
+    b = -2.0 * lsp[0]
+    f[1] = b
+    for i=2 to 5 do
+        b = -2.0 * lsp[2*i-2];
+        for j=i-1 down to 2 do
+            f[j] = f[j] + b*f[j-1] + f[j-2];
+        f[1] = f[1] + b;

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Deleted variables listed in the Local Stores Needed/Modified
+          sections.
+
+ Description: Updated file per comments from Phase 2/3 review.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Fixed typecasting issue with TI C compiler. Updated copyright
+              year.
+
+ Description:
+ (1) Removed instance of static in the const table "inter_6"
+ (2) Changed Overflow from a global to a parameter passed via a pointer.
+ (3) Made numerous small changes to bring code more in line with PV standards.
+
+ Description:  For pred_ltp()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation
+              4. Unrolled loops to speed up processing, use decrement loops,
+                 loaded into memory filter coefficient in linear order for
+                 faster execution in main loop.
+              5. Eliminated call to round by proper initialization
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations
+
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description: Placed code in the PV standard template format.
+ Updated to accept new parameter, Flag *pOverflow.
+
+ Description:
+              Eliminated unused include files.
+              For Vq_subvec()
+              1. Eliminated math operations that unnecessary checked for
+                 saturation (number are bounded to 2^12)
+              2. Eliminated access to (slow) memory by using axiliar variables
+              3. Because this routine is looking for the minimum distance,
+                 introduced 3 check conditions inside the loop, so when the
+                 partial distance is bigger than the minimun distance, the
+                 loop is not completed and process continue with next iteration
+              For Vq_subvec_s()
+              1. Eliminated math operations that unnecessary checked for
+                 saturation (number are bounded to 2^12)
+              2. Combined increasing and decreasing loops to avoid double
+                 accesses to the same table element
+              3. Eliminated access to (slow) memory by using axiliar variables
+              4. Because this routine is looking for the minimum distance,
+                 introduced 2 check conditions inside the loop, so when the
+                 partial distance is bigger than the minimun distance, the
+                 loop is not completed and process continue with next iteration
+              For Q_plsf_5()
+              1. Eliminated math operations that unnecessary checked for
+                 saturation (number are bounded to 2^12)
+              2. Replaced array addressing by pointers
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+
+ Description: Added #ifdef __cplusplus around extern'ed table.

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Quantization of 2 sets of LSF parameters using 1st order MA
+           prediction and split by 5 matrix quantization (split-MQ)
+
+ DESCRIPTION:
+
+      p[i] = pred_factor*past_rq[i];   i=0,...,m-1
+      r1[i]= lsf1[i] - p[i];           i=0,...,m-1
+      r2[i]= lsf2[i] - p[i];           i=0,...,m-1
+ where:
+      lsf1[i]           1st mean-removed LSF vector.
+      lsf2[i]           2nd mean-removed LSF vector.
+      r1[i]             1st residual prediction vector.
+      r2[i]             2nd residual prediction vector.
+      past_r2q[i]       Past quantized residual (2nd vector).
+
+ The residual vectors r1[i] and r2[i] are jointly quantized using
+ split-MQ with 5 codebooks. Each 4th dimension submatrix contains 2
+ elements from each residual vector. The 5 submatrices are as follows:
+   {r1[0], r1[1], r2[0], r2[1]};  {r1[2], r1[3], r2[2], r2[3]};
+   {r1[4], r1[5], r2[4], r2[5]};  {r1[6], r1[7], r2[6], r2[7]};
+                  {r1[8], r1[9], r2[8], r2[9]}

+              2. Changed Input range definitions.
+
+ Description: Made changes based on review meeting.
+              1. Changed Overflow definition.
+              2. Removed pseudo-code.
+              3. Deleted (var2>15&&var1!=0) condition.
+              4. Moved var2>0 condition in front of var2<0 condition.
+
+ Description: Changed the function prototype to pass in a pointer to the

+
+ This function computes sqrt(L_x),  where  L_x is positive.
+ If L_var is negative or zero, the result is 0
+
+ The function sqrt(L_x) is approximated by a table and linear
+ interpolation. The square root is computed using the
+ following steps:
+    1- Normalization of L_x.
+    2- If exponent is even then shift right once.
+    3- exponent = exponent/2
+    4- i = bit25-b31 of L_x;  16<=i<=63  because of normalization.
+    5- a = bit10-b24
+    6- i -=16
+    7- L_y = table[i]<<16 - (table[i] - table[i+1]) * a * 2
+    8- return L_y and exponent so caller can do denormalization

+ REVISION HISTORY
+
+ Description: Making changes based on comments from the review meeting.
+
+ Description: Added typedef to Input/Output Definition section.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template.
+
+ Description: Fixed typecasting issue with the TI C compiler.
+
+ Description: Modified FOR loops to count down.
+
+ Description: Modified FOR loop to count up again so that the correct values
+              are stored in the tmp buffer. Updated copyright year.
+
+ Description:
+        - Modified for loop and introduced pointers to avoid adding
+          offsets
+        - Eliminated check for saturation given that the max values of input
+          data and coefficients will not saturate the multiply and
+          accumulation
+        - eliminated memcpy to update history buffer in every pass. This is
+          done now just updating the pointers.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Unrolled loops to process twice as many samples as before,
+                 this saves on memory accesses to the vector coeff. a[] and
+                 elements in the history buffer of this recursive filter
+
+ Description:
+              1. Added overflow check inside both loops. (this is needed just
+                 to satisfy bit exactness on the decoder, a faster
+                 implementation will add an extra shift, do the same,
+                 but will not be bit exact, and it may have better audio
+                 quality because will avoid clipping)
+              2. Added include file for constant definitions
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Using fxp_arithmetic.h that includes inline assembly functions
+              for ARM and linux-arm.
+
+ Description: Replacing fxp_arithmetic.h with basic_op.h.

+ REVISION HISTORY
+
+ Description:       AMRDecode now doesn't call getbits() or put_header_in().
+                    It also now obtains a new bit_offset value from a constant
+                    rather than from the returned value of getbits().
+
+ Description:       AMRDecode now returns byte_offset rather than bit_offset,
+                    so the program can access the next frame that is byte
+                    aligned rather than packed without padding.
+
+ Description:       The structure types Speech_Decode_FrameState are now
+                    passed into amrdecode( ) using void pointers, so that
+                    higher level functions don't need to know anything about
+                    this structure type.
+
+ Description: Changed input argument list. Added code to handle incoming DTX
+              frames, and added call to wmf_to_ets function prior to calling
+              GSMFrameDecode.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Changed all references to bit_offset to byte_offset.
+
+ Description: Added input_type to the function interface and modified code
+              to check type of conversion that needs to be made.
+
+ Description: Modified pseudo-code to include IF2 and ETS input formats.
+              Removed byte_offset from input list. Renamed speech_bits
+              to speech_bits_ptr.
+
+ Description: Added dec_input_format_tab.h in Include section. Modified
+              pseudo-code to use correct table names. Renamed input_type to
+              input_format and speech_bits to speech_bits_ptr.
+
+ Description: Removed *prev_mode_ptr in the input argument list.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Removed dec_input_format_tab.h from Include section.
+              2. Changed type definition of raw_pcm_buffer in the I/O
+                 definition section.
+
+ Description: Renamed WmfBytesPerFrame to WmfDecBytesPerFrame, and
+              If2BytesPerFrame to If2DecBytesPerFrame.
+
+ Description: Modified code so that the ETS testvectors could be fed directly
+              to this function.
+
+ Description: Changed '&' to '&&' in the setting of rx_type and mode for
+              AMR_SID < frame_type < NO_DATA case.
+
+ Description: Added code comments and made some code optimizations per Phase
+              2/3 review comments.
+
+ Description: Added conditional compile around the call to GSMFrameDecode to
+              allow amrdecode.c to be used in the ETS reference console.

+ FUNCTION DESCRIPTION
+
+ This function is the top level entry function to the GSM AMR Decoder library.
+
+ First, it checks the input format type (input_format) to determine the type
+ of de-formattting that needs to be done. If input_format is AMR_WMF, the input
+ data is in WMF (aka, non-IF2) format and the function wmf_to_ets will be
+ called to convert to the ETS format (1 bit/word, where 1 word = 16 bits),
+ and byte_offset will be updated according to the contents of WmfDecBytesPerFrame
+ table.
+
+ If input_format is AMR_IF2, the input data is in IF2 format [1] and the
+ function if2_to_ets will be called to convert to the ETS format, and
+ byte_offset will be updated according to the contents of If2DecBytesPerFrame
+ table.
+
+ The codec mode and receive frame type is initialized based on the incoming
+ frame_type.
+
+ If input_format is AMR_ETS, the input data is in the ETS format. The receive
+ frame type is set to the value in the first location of the buffer pointed to
+ by speech_bits_ptr. Then, the encoded speech parameters in the buffer pointed
+ to by speech_bits is copied to dec_ets_input_bfr and the type will be changed
+ from unsigned char to Word16. Lastly, if the receive frame type is not
+ RX_NO_DATA, the mode is obtained from the buffer pointed to by
+ speech_bits_ptr, offset by MAX_SERIAL_SIZE+1, otherwise, the mode is set to
+ the previous mode (found the in state_data->prev_mode).
+
+ If input_format is an unsupported format, byte_offset will be set to -1, to
+ indicate an error condition has occurred, and the function will exit.
+
+ If there are no errors, GSMFrameDecode is called to decode a 20 ms frame. It
+ puts the decoded linear PCM samples in the buffer pointed to by
+ raw_pcm_buffer. Then, the prev_mode field of the structure pointed to by
+ state_data is updated to the current mode.
+
+ This function returns the new byte_offset value to indicate the address
+ offset of the next speech frame to be decoded.

+------------------------------------------------------------------------------
+ REVISION HISTORY
+
+ Description: Added BytesUsed table so that the code can allow for padding
+              at the end of each frame.
+
+ Description: Removed function prototypes for getbits, putbits,
+              put_frame_header_in, and get_frame_header_off. Removed
+              basicop_malloc.h and replaced it with typedef.h in the include
+              section. Fixed table entries for various SID modes. Removed
+              #defines because they are not used by AMRDecode function.
+              Removed tables not used by AMRDecode function.
+
+ Description: The data type Speech_Decode_FrameState is now being passed into
+              this function as a void pointer rather than a structure of type
+              Speech_Decode_FrameState.
+
+ Description: The variable decoder_state was renamed to state_data.
+
+ Description: Updated function prototype and header template.
+
+ Description: Added mode.h and frame_type_3gpp.h to include section, and
+              removed sp_dec.h.
+
+ Description: Removed definition of Changed BytesThisFrame[] table. Added
+              extern declaration for BytesThisFrame[] table.
+
+ Description: Added #define for WMF and IF2. Updated function prototype.
+
+ Description: Moved input format #defines and BytesThisFrame table to
+              dec_input_format_tab.h and dec_input_format_tab.c, respectively.
+              Updated function prototype.
+
+ Description: Updated function prototype of AMRDecode due to the removal of
+              *prev_mode_ptr. Added extern of If2BytesPerFrame
+
+ Description: Added #defines for WMF, IF2, and ETS input formats.
+
+ Description: Changed WmfBytesPerFrame to WmfDecBytesPerFrame, and
+              If2BytesPerFrame to If2DecBytesPerFrame.
+
+ Description: Renamed #defines for input format types to make it unique to the
+              decoder.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Moved _cplusplus #ifdef after Include section.

+ REVISION HISTORY
+
+ Description:
+ (1) Updated to accept new parameter, Flag *pOverflow.
+ (2) Placed file in the proper PV Software template.
+
+ Description:
+ (1) Removed "count.h" and "basic_op.h" and replaced with individual include
+     files (add.h, sub.h, etc.)
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Decoding of fractional pitch lag with 1/3 resolution.
+           Extract the integer and fraction parts of the pitch lag from
+           the received adaptive codebook index.
+
+  See "Enc_lag3.c" for more details about the encoding procedure.
+
+  The fractional lag in 1st and 3rd subframes is encoded with 8 bits
+  while that in 2nd and 4th subframes is relatively encoded with 4, 5
+  and 6 bits depending on the mode.

+ REVISION HISTORY
+
+ Description:
+ (1) Updated to accept new parameter, Flag *pOverflow.
+ (2) Placed file in the proper PV Software template.
+
+ Description:
+ (1) Removed "count.h" and "basic_op.h" and replaced with individual include
+     files (add.h, sub.h, etc.)
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Decoding of fractional pitch lag with 1/6 resolution.
+           Extract the integer and fraction parts of the pitch lag from
+           the received adaptive codebook index.
+
+  See "Enc_lag6.c" for more details about the encoding procedure.
+
+  The fractional lag in 1st and 3rd subframes is encoded with 9 bits
+  while that in 2nd and 4th subframes is relatively encoded with 6 bits.
+  Note that in relative encoding only 61 values are used. If the
+  decoder receives 61, 62, or 63 as the relative pitch index, it means
+  that a transmission error occurred. In this case, the pitch lag from
+  previous subframe (actually from previous frame) is used.

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from IF2 to ETS. IF2 is the storage format where the frame type
+ is in the first four bits of the first byte. The upper four bits of that byte
+ contain the first four encoded speech bits for the frame. The following bytes
+ contain the rest of the encoded speech bits. The final byte has padded zeros
+ to make the frame byte aligned. ETS format has the encoded speech
+ bits each separate with only one bit stored in each word.

+
+ Also, placed code in the proper PV Software Template.
+
+ Description: Per review comments, updated the inputs/outputs section
+ for the function lsp_avg.
+
+ Description: Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description: Per review comments, I added a description of pOverflow
+ to the input/output section of the template.  I also removed an unnecessary
+ include file, <stdio.h>
+
+ Description: Removed q_plsf_5.tab from Include section and added
+              q_plsf_5_tbl.h to Include section. Changed "mean_lsf"
+              to "mean_lsf_5" in lsp_avg_reset().
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ order high pass filter with cutoff frequency of 60 Hz, and up-scaling the
+ output speech by a factor of 2. In addition to the post-processing function
+ itself, a post-processing initialization function, post-processing reset
+ function, and post-processing exit function are also included in this file.

+    signal = buffer containing the input signal (Word16)
+    lg = length of the input signal (Word16)
+    pOverflow = pointer to overflow indicator of type Flag
+
+ Outputs:
+    structure pointed to by st contains new filter input and output values
+    signal buffer contains the HP filtered and up-scaled input signal
+    pOverflow points to 1 if overflow occurs in the math functions called
+              else it points to 0.
+
+ Returns:
+    return_value = 0 (int)
+
+ Global Variables Used:
+    a = buffer containing filter coefficients
+    b = buffer containing filter coefficients
+
+ Local Variables Needed:
+    None
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function performs post-processing on the output speech signal. First,
+ the output speech goes through a second order high pass filter with a
+ cutoff frequency of 60 Hz. Then, the filtered output speech is multiplied
+ by a factor of 2. The algorithm implemented follows the following difference
+ equation:
+
+ y[i] = b[0]*x[i]*2 + b[1]*x[i-1]*2 + b[2]*x[i-2]*2 + a[1]*y[i-1] + a[2]*y[i-2];

+ REVISION HISTORY
+
+ Description: Changed template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Updated file per comments gathered from Phase 2/3 review.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Replaced basic_op.h with the header file of the math functions
+              used in the file.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Updated copyright year.
+              2. Modified FOR loops to count down.
+              3. Fixed typecasting issue with TI C compiler.
+              4. Added "break" statement after overflow condition occurs.
+
+ Description: Removed the functions pstfilt_init and pstfilt_exit.
+ The pst_filt related structure is no longer dynamically allocated.
+
+ Description: Modified code for EPOC changes where pOverflow is passed in
+              rather than allowing overflow to be a global variable.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations

+ REVISION HISTORY
+
+ Description: Add PV coding template. Filled out template sections and
+              reformatted code to follow C coding standard. Removed code that
+              handles SID in GSMFrameDecode.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Updated to more recent PV C coding template.
+              2. Took out all the tabs in the file and replaced with spaces.
+              3. Deleted bit_offset from input list of GSMFrameDecode.
+
+ Description: Changing several variables passed into these functions of type
+              Speech_Decode_FrameState to type void.
+
+ Description: Cleaning up brackets and line spacing for statements with
+              brackets as per a review comments.
+
+ Description: Synchronized file with UMTS version 3.2.0. Removed unnecessary
+              include files.
+
+ Description: Removed all references to malloc/free, except for the top-level
+ malloc in GSMInitDecode, and corresponding free in GSMDecodeFrameExit.
+
+ Also, modified function calls throughout to reflect the fact that the members
+ of the structure Decoder_amrState are no longer pointers to be set via
+ malloc, but full-blown structures.  (Changes of the type D_plsfState *lsfState
+ to D_plsfState lsfState)
+
+ Description: Created overflow and pass the variable into the decoder.
+
+ Description: Changed inititlaization of the pointer to overflow flag. Removed
+              code related to MOPS counter.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with defined types.
+               Added proper casting (Word32) to some left shifting operations

+ FUNCTION DESCRIPTION
+
+ This function is the entry point to the GSM AMR decoder. The following
+ operations are performed on one received frame: First, the codec
+ parameters are parsed from the buffer pointed to by serial according to
+ frame_type. Then the AMR decoder is invoked via a call to Decoder_amr. Post
+ filtering of the decoded data is done via a call to Post_Filter function.
+ Lastly, the decoded data is post-processed via a call to Post_Process
+ function. If NO13BIT is not defined, the contents of the buffer pointed to
+ by synth is truncated to 13 bits. It remains unchanged otherwise.

+ Telecommunication Standard). WMF format has the encoded speech bits byte
+ aligned with MSB to LSB going left to right. ETS format has the encoded speech
+ bits each separate with only one bit stored in each word.

+ FUNCTION DESCRIPTION
+
+ This function is the top-level entry point to the GSM AMR Encoder library.
+
+ The following describes the encoding process for WMF or IF2 formatted output
+ data. This functions calls GSMEncodeFrame to encode one frame's worth of
+ input speech samples, and returns the newly encoded bit stream in the buffer
+ pointed to by pEncOutput.Then the function sid_sync is called to determine
+ the transmit frame type. If the transmit frame type is TX_SPEECH_GOOD or
+ TX_SID_FIRST or TX_SID_UPDATE, p3gpp_frame_type will be set to the encoder
+ used mode. For SID frames, the SID type information and mode information are
+ added to the encoded parameter bitstream according to the SID frame format
+ described in [1]. If the transmit frame type is TX_NO_DATA, the store
+ pointed to by p3gpp_frame_type will be set to NO_DATA. Then the output
+ format type (output_format) will be checked to determine the format of the
+ encoded data.
+
+ If output_format is AMR_TX_WMF, the function ets_to_wmf will be called to
+ convert from ETS format (1 bit/word, where 1 word = 16 bits, information in
+ least significant bit) to WMF (aka, non-IF2). The WMF format stores the data
+ in octets. The least significant 4 bits of the first octet contains the 3GPP
+ frame type information and the most significant 4 bits are zeroed out. The
+ succeeding octets contain the packed encoded speech bits. The total number of
+ WMF bytes encoded is obtained from WmfEncBytesPerFrame table and returned via
+ num_enc_bytes.
+
+ If output_format is AMR_TX_IF2, the function if2_to_ets will be called to
+ convert from ETS format to IF2 [1]. The IF2 format stores the data in octets.
+ The least significant nibble of the first octet contains the 3GPP frame type
+ and the most significant nibble contains the first 4 encoded speech bits. The
+ suceeding octets contain the packed encoded speech bits. The total number of
+ IF2 bytes encoded is obtained from If2EncBytesPerFrame table and returned via
+ num_enc_bytes.
+
+ If output_format is AMR_TX_ETS, GSMFrameEncode is called to generate the
+ encoded speech parameters, then, sid_sync is called to determine the transmit
+ frame type. If the transmit frame type is not TX_NO_DATA, then the transmit
+ frame type information is saved in the first location of the ets_output_bfr,
+ followed by the encoded speech parameters. The codec mode information is
+ stored immediately after the MAX_SERIAL_SIZE encoded speech parameters. If
+ the transmit frame type is TX_NO_DATA, the transmit frame type, encoded
+ speech parameters, and codec mode are stored in the same order as before
+ in ets_output_bfr. However, for the no data case, the codec mode is set to
+ -1.
+
+ After all the required information is generated, the 16-bit data generated
+ by the Encoder (in ets_output_bfr) is copied to the buffer pointed to by
+ pEncOutput in the little endian configuration, i.e., least significant byte,
+ followed by most significant byte. The num_enc_bytes is set to
+ 2*(MAX_SERIAL_SIZE+2).
+
+ If output_format is invalid, this function flags the error and sets
+ num_enc_bytes to -1.

+ REVISION HISTORY
+
+ Description: Put into template...starting optimization.
+
+ Description: Removed call to mult_r routine.
+
+ Description: Modified Input/Output Definitions section to comply with the
+          current template. Fixed tabs.
+
+ Description: Updated Input/Output definitions by making them more
+          descriptive.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Added full pathname of file.
+              2. Fixed typecasting issue with TI compiler.
+              3. Modified FOR loops to count down.
+              4. Added comment to the code.
+
+ Description: Removed extern to global paramter (Flag Overflow) and replaced
+ by passing in a pointer to Overflow.  Also, made several small changes to
+ bring code more in line with PV Standards.
+
+ Description:
+            1. Added pointer to avoid adding offsets in every pass
+            2. Break last loop in two nested loop to speed up processing
+            3. Removed extra check for overflow by doing scaling right
+               after overflow is detected.
+            4. Eliminated calls to basic operations (like extract) not
+               needed because of the nature of the number (all bounded)
+
+ Description:
+              1. Fixed for:
+                overflow check was looking for positive number before a left
+                shift. When numbers were big enough, positive numbers after
+                shifted became negative, causing a 1/0 division).
+                Fixed so now it checks for numbers lesser than 0x40000000
+                before the left shift
+
+ Description:
+              1.Modified check for saturation to match bit exact test.
+                Also, when saturation is reached, a faster loop is used
+                (with no energy accumulation) to speed up processing
+
+
+ Description:
+              1.Added pointer initialization to for loop when saturation
+                is found. This because some compiler ( like Vcpp in release
+                mode) when optimizing code, may remove pointer information
+                once the loop is broken.
+
+ Description:  Added casting to eliminate warnings
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Using inlines from fxp_arithmetic.h.
+
+ Description: Replacing fxp_arithmetic.h with basic_op.h.

+ FUNCTION NAME: Autocorr
+----------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    x = buffer of input signals of type Word16
+    m = LPC order of type Word16
+    wind = buffer of window signals of type Word16
+    r_h = buffer containing the high word of the autocorrelation values
+          of type Word16
+    r_l = buffer containing the low word of the autocorrelation values
+          of type Word16
+
+    pOverflow = pointer to variable of type Flag *, which indicates if
+                overflow occurs.
+
+ Outputs:
+    r_h buffer contains the high word of the new autocorrelation values
+    r_l buffer contains the low word of the new autocorrelation values
+    pOverflow -> 1 if overflow occurs.
+
+ Returns:
+    norm = normalized autocorrelation at lag zero of type Word16
+
+ Global Variables Used:
+    None
+
+ Local Variables Needed:

+ FUNCTION DESCRIPTION
+
+ This function searches a 35 bit algebraic codebook containing 10 pulses in a
+ frame of 40 samples.
+
+ The code contains 10 nonzero pulses: i0...i9.
+ All pulses can have two possible amplitudes: +1 or -1.
+ The 40 positions in a subframe are divided into 5 tracks of
+ interleaved positions. Each track contains two pulses.
+ The pulses can have the following possible positions:
+
+    i0, i5 :  0, 5, 10, 15, 20, 25, 30, 35.
+    i1, i6 :  1, 6, 11, 16, 21, 26, 31, 36.
+    i2, i7 :  2, 7, 12, 17, 22, 27, 32, 37.
+    i3, i8 :  3, 8, 13, 18, 23, 28, 33, 38.
+    i4, i9 :  4, 9, 14, 19, 24, 29, 34, 39.
+
+ Each pair of pulses require 1 bit for their signs and 6 bits for their
+ positions (3 bits + 3 bits). This results in a 35 bit codebook.
+ The function determines the optimal pulse signs and positions, builds
+ the codevector, and computes the filtered codevector.

+     FUNCTION DESCRIPTION
+
+     This function searches a 9 bit algebraic codebook containing 2 pulses in a
+     frame of 40 samples.
+
+     The code length is 40, containing 2 nonzero pulses: i0...i1. All pulses can
+     have two possible amplitudes: +1 or -1. Pulse i0 can have 8 possible positions,
+     pulse i1 can have 8 positions. Also coded is which track pair should be used,
+     i.e. first or second pair. Where each pair contains 2 tracks.
+
+        First subframe:
+        first   i0 :  0, 5, 10, 15, 20, 25, 30, 35.

+ REVISION HISTORY
+
+ Description: Modified to pass overflow flag through to basic math function.
+ The flag is passed back to the calling function by pointer reference.
+
+ Description: Optimized file to reduce clock cycle usage. Updated copyright
+              year. Removed unneccesary include files and added only the
+              include files for the math functions used. Removed unused
+              #defines.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ FUNCTION DESCRIPTION
+
+ FUNCTION:
+
+ PURPOSE:  Searches a 31 bit algebraic codebook containing 8 pulses
+           in a frame of 40 samples.
+
+ DESCRIPTION:
+   The code contains 8 nonzero pulses: i0...i7.
+   All pulses can have two possible amplitudes: +1 or -1.
+   The 40 positions in a subframe are divided into 4 tracks of
+   interleaved positions. Each track contains two pulses.
+   The pulses can have the following possible positions:
+
+      i0, i4 :  0, 4, 8,  12, 16, 20, 24, 28, 32, 36
+      i1, i5 :  1, 5, 9,  13, 17, 21, 25, 29, 33, 37
+      i2, i6 :  2, 6, 10, 14, 18, 22, 26, 30, 34, 38
+      i3, i7 :  3, 7, 11, 15, 19, 23, 27, 31, 35, 39
+
+   Each pair of pulses require 1 bit for their signs. The positions
+   are encoded together 3,3 and 2 resulting in
+   (7+3) + (7+3) + (5+2) bits for their
+   positions. This results in a 31 (4 sign and 27 pos) bit codebook.
+   The function determines the optimal pulse signs and positions, builds
+   the codevector, and computes the filtered codevector.

+ REVISION HISTORY
+
+ Description: Made changes based on comments from the review meeting.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Added initialization of the overflow flag in cod_amr_init()
+              and in cod_amr_reset(). This overflow flag is now part of
+              the cod_amrState structure.
+
+ Description: Cleaned up INCLUDES. removed inclusion of basic_op.h and repeat
+              inclusion of copy.h
+
+ Description: Updated function call to dtx_enc
+
+ Description:  For cod_amr_first() and cod_amr()
+              1. Replaced copy() function with memcpy()
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ FUNCTION DESCRIPTION
+
+ This function is the main encoder routine. It is called every 20 ms speech
+ frame, operating on the newly read 160 speech samples. It performs the
+ principle encoding functions to produce the set of encoded parameters
+ which include the LSP, adaptive codebook, and fixed codebook
+ quantization indices (addresses and gains).
+
+ Before calling this function, 160 new speech data should be copied to the
+ vector new_speech[]. This is a global pointer which is declared in
+ this file (it points to the end of speech buffer minus 160).
+
+ The outputs of the function are:
+     ana[]:     vector of analysis parameters.
+     synth[]:   Local synthesis speech (for debugging purposes)

+ REVISION HISTORY
+
+ Description: Optimize for speed. Update to code template.
+
+ Description: Added author name and date, fixed tabs, and added missing
+          sections. Updated Input/Output section.
+
+ Description: Optimized code by calculating two convolution sums per iteration
+          of the outer loop, thereby, decreasing outer loop count by 2.
+          Updated input/output definitions to be the same as the assembly
+          file (convolve.asm). Left Pseudo-code section blank.
+
+ Description: Deleted semi-colon in the Pointers modified section.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Fixed typecasting issue with TI C compiler.
+              2. Modified FOR loop to count down, wherever applicable.
+
+ Description: Made the following changes
+              1. Unrolled the correlation loop.
+              2. Performed 2 correlation per pass per sample to avoid recalling
+                 the same data twice.
+              3. Eliminated math operations that check for saturation.
+
+ Description:
+              1. Modified loop counter, extra unrolling did speed up code
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Used MAX_16 and MIN_16 when checking the result of Inv_sqrt.
+          Synced up to the new template.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Took out cor_h_x function and put it in its own file. Sync'ed
+          up with the single_func_template.c template. Delete version
+          ID variable.
+
+ Description: Synchronized file with UTMS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Fixed portion of the code that builds the rr[] matrix. There
+              was an error in the original inlining of code that caused
+              the code to be not bit-exact with UMTS version 3.2.0.
+
+ Description: Added calls to L_add() and mult() in the code to handle overflow
+              scenario. Moved cor_h.h after cnst.h in the Include section.
+              Doing this allows the unit test to build using the cnst.h in the
+              /test/include directory. Fixed initialization of the accumulator
+              in the first calculation of the sum of squares.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Used #define value instead of hard-coded numbers in the code.
+              2. Fixed typecasting issue with TI C compiler.
+              3. Removed typecasting of 0x00008000L in the call to L_add.
+
+ Description: Changed pOverflow from a global variable into a function
+ parameter.
+
+ Description:
+            1. Added pointer to avoid adding offsets in every pass
+            2. Eliminate variables defined as registers
+            3. Removed extra check for overflow by doing scaling right
+               after overflow is detected.
+            4. Eliminated calls to basic operations (like extract) not
+               needed because of the nature of the number (all bounded)
+            5. Eliminated duplicate loop accessing same data
+            6. Simplified matrix addressing by use of pointers
+
+ Description:
+              1. Eliminated unused include files.
+              2. Access twice the number of points when delaing with matrices
+                 and in the process only 3 pointers (instead of 4) are needed
+              3. Replaced array addressing (array sign[]) by pointers
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Using inlines from fxp_arithmetic.h .
+
+ Description: Replacing fxp_arithmetic.h with basic_op.h.

+ REVISION HISTORY
+
+ Description: Created a separate file for cor_h_x function.
+
+ Description: Synchronized file with UMTS versin 3.2.0. Updated coding
+              template.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Modified FOR loop in the code to count down.
+              2. Fixed typecasting issue with TI C compiler.
+
+ Description: Added call to round() and L_shl() functions in the last FOR
+              loop to make code bit-exact. Updated copyright year.
+
+ Description: Modified to pass pOverflow in via a pointer, rather than
+ invoking it as a global variable.
+
+ Description: Made the following changes
+              1. Unrolled the correlation loop and add mechanism control
+                 to compute odd or even number of computations.
+              2. Use pointer to avoid continuos addresses calculation
+              2. Eliminated math operations that check for saturation.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ FUNCTION DESCRIPTION
+
+ This function computes the correlation between the target signal (x) and the
+ impulse response (h).
+
+ The correlation is given by: d[n] = sum_{i=n}^{L-1} x[i] h[i-n],
+ where: n=0,...,L-1
+
+ d[n] is normalized such that the sum of 5 maxima of d[n] corresponding to
+ each position track does not saturate.

+    nb_track = number of ACB tracks (Word16)
+    step = step size between pulses in one track (Word16)
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    dn contents are the newly calculated correlation values
+    pOverflow = 1 if the math functions called by cor_h_x2 result in overflow
+    else zero.
+
+ Returns:
+    None

+ FUNCTION DESCRIPTION
+
+ This function computes the correlation between the target signal (x) and the
+ impulse response (h).
+
+ The correlation is given by: d[n] = sum_{i=n}^{L-1} x[i] h[i-n],
+ where: n=0,...,L-1
+
+ d[n] is normalized such that the sum of 5 maxima of d[n] corresponding to
+ each position track does not saturate.

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template. First attempt at
+          optimizing C code.
+
+ Description: Updated file per comments gathered from Phase 2/3 review.
+          Synched up with new template (Inputs/Outputs section). Deleted
+          lines leftover from original code prior to the code section of
+          dtx_enc_exit function. Deleted confusing comment in the log_en
+          calculation in dtx_enc function. Restructured IF statement in
+          the calculation of the sum of squares of speech signals in
+          dtx_buffer.
+
+ Description: Added setting of Overflow flag in inlined code.
+
+ Description: Synchronized file with UTMS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Modified FOR loops to count down.
+              2. Fixed typecasting issue with TI C compiler.
+              3. Fixed comment in dtx_enc pseudo-code.
+              4. Added dtx_enc code comment pertaining to possible assembly
+                 implementation.
+
+ Description: Added calls to add() in tx_dtx_handler. Updated copyright year.
+
+ Description: Pass in pointer to overflow flag to all functions requiring this
+              flag. This is to make the library EPOC compatible.
+
+ Description:  For dtx_enc_reset() only
+              1. Replaced copy() with memcpy.
+              2. Eliminated include file copy.h
+              3. Eliminated printf statement
+              For dtx_buffer()
+              1. Replaced copy() with memcpy.
+              2. Eliminated math operations that unnecessary checked for
+                 saturation, in some cases this by shifting before adding and
+                 in other cases by evaluating the operands
+              3. Unrolled loop to speed up execution
+
+ Description:  For dtx_buffer()
+              1. Modified scaling and added check for saturation. Previous
+                 scaling was correct but altered precision, this cause bit
+                 exactness test failure.
+
+ Description:  For dtx_buffer()
+              1. Modified scaling and saturation checks. Previous
+                 scaling was correct but altered precision, this cause bit
+                 exactness test failure for dtx vad2.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ FUNCTION DESCRIPTION
+
+ This function implements the encoding of fractional pitch lag with
+ 1/3 resolution.
+
+ *   FUNCTION:  Enc_lag3
+ *
+ *   PURPOSE:  Encoding of fractional pitch lag with 1/3 resolution.
+ *
+ *   DESCRIPTION:
+ *                    First and third subframes:
+ *                    --------------------------
+ *   The pitch range is divided as follows:
+ *           19 1/3  to   84 2/3   resolution 1/3
+ *           85      to   143      resolution 1
+ *
+ *   The period is encoded with 8 bits.
+ *   For the range with fractions:
+ *     index = (T-19)*3 + frac - 1;
+ *                         where T=[19..85] and frac=[-1,0,1]
+ *   and for the integer only range
+ *     index = (T - 85) + 197;        where T=[86..143]
+ *
+ *                    Second and fourth subframes:
+ *                    ----------------------------
+ *   For the 2nd and 4th subframes a resolution of 1/3 is always used,
+ *   and the search range is relative to the lag in previous subframe.
+ *   If t0 is the lag in the previous subframe then
+ *   t_min=t0-5   and  t_max=t0+4   and  the range is given by
+ *        t_min - 2/3   to  t_max + 2/3
+ *
+ *   The period in the 2nd (and 4th) subframe is encoded with 5 bits:
+ *     index = (T-(t_min-1))*3 + frac - 1;
+ *                 where T=[t_min-1..t_max+1]

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Encoding of fractional pitch lag with 1/6 resolution.
+
+ DESCRIPTION:
+                  First and third subframes:
+                  --------------------------
+ The pitch range is divided as follows:
+         17 3/6  to   94 3/6   resolution 1/6
+         95      to   143      resolution 1
+
+ The period is encoded with 9 bits.
+ For the range with fractions:
+   index = (T-17)*6 + frac - 3;
+                       where T=[17..94] and frac=[-2,-1,0,1,2,3]
+ and for the integer only range
+   index = (T - 95) + 463;        where T=[95..143]
+
+                  Second and fourth subframes:
+                  ----------------------------
+ For the 2nd and 4th subframes a resolution of 1/6 is always used,
+ and the search range is relative to the lag in previous subframe.
+ If t0 is the lag in the previous subframe then
+ t_min=t0-5   and  t_max=t0+4   and  the range is given by
+     (t_min-1) 3/6   to  (t_max) 3/6
+
+ The period in the 2nd (and 4th) subframe is encoded with 6 bits:
+   index = (T-(t_min-1))*6 + frac - 3;
+               where T=[t_min-1..t_max] and frac=[-2,-1,0,1,2,3]
+
+ Note that only 61 values are used. If the decoder receives 61, 62,
+ or 63 as the relative pitch index, it means that a transmission
+ error occurred and the pitch from previous subframe should be used.

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from ETS (European Telecommunication Standard) to IF2. ETS format
+ has the encoded speech bits each separate with only one bit stored in each
+ word. IF2 is the storage format where the frame type is in the first four bits
+ of the first byte. The upper four bits of that byte contain the first four
+ encoded speech bits for the frame. The following bytes contain the rest of
+ the encoded speech bits. The final byte has padded zeros  to make the frame
+ byte aligned.

+ FUNCTION DESCRIPTION
+
+ This function performs a transformation on the data buffers. It converts the
+ data format from ETS (European Telecommunication Standard) to WMF (wireless
+ multimedia forum). ETS format has the encoded speech bits each separate with
+ only one bit stored in each word. WMF is the storage format where the frame
+ type is in the first four bits of the first byte. This first byte has the
+ upper four bits as padded zeroes. The following bytes contain the rest of the
+ encoded speech bits. The final byte has padded zeros to make the frame byte
+ aligned.

+ FUNCTION DESCRIPTION
+
+ This function computes the pitch (adaptive codebook) gain. The adaptive
+ codebook gain is given by
+
+    g = <x[], y[]> / <y[], y[]>
+
+    where:  x[] is the target vector
+            y[] is the filtered adaptive codevector
+            <> denotes dot product.
+
+ The gain is limited to the range [0,1.2] (=0..19661 Q14)
+

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description: Removed everything associated with gc_pred_init
+ and gc_pred_exit.  gc_pred_exit was simply removed -- gc_pred_init
+ was replaced with calls to gc_pred_reset.  This is because the gc_pred
+ related structures are no longer dynamically allocated via malloc.
+
+ Description:  For gainQuant()
+              1. Replaced gc_pred_copy() with memcpy.
+              2. Eliminated unused include file gc_pred.h.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ REVISION HISTORY
+
+ Description: Placed header file in the proper template format.  Added
+ parameter pOverflow.
+
+ Description: Changed definition of...
+
+    gc_predState     gc_predSt;
+    gc_predState     gc_predUnqSt;
+
+  in the structure typedef.  These are no longer pointers, which avoids
+  the need to malloc memory for the pointers.  They are, rather, the actual
+  structure declared within the gainQuantState structure.
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Moved _cplusplus #ifdef after Include section.
+

+ REVISION HISTORY
+
+ Description: Changing code as per review comments. These changes include
+              removing unnecessary tables and changing function descriptions.
+              The comments were changed to "slash-star" rather than double
+              slash, and some wordings of comments were corrected.
+
+ Description: Replaced GSMEncodeFrame function prototype with that of
+              AMREncode. Updated copyright year.
+
+ Description: Added #define for WMF and IF2, and updated function prototype
+              of AMREncode.
+
+ Description: Renamed WMF and IF2 to AMR_WMF and AMR_IF2, respectively. Added
+              AMR_ETS, and changed output_type to output_format in the
+              function prototype of AMREncode(). Removed function prototypes
+              for frame_header_move() and reverse_bits() since they are not
+              needed anymore.
+
+ Description: Moved WMFBytesUsed and IF2BytesUsed tables to
+              enc_output_format_tab.c.
+
+ Description: Added function prototypes for init, reset, and exit functions
+              in amrencode.c. Renamed output format #defines so that it it
+              unique to the encoder.
+
+ Description: Added comment to describe L_FRAME.
+
+ Description: Added Frame_Type_3GPP type definition.
+
+ Description: Moved _cplusplus #ifdef after Include section.

+ REVISION HISTORY
+
+ Description:
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation
+              4. Unrolled loops to speed up processing, use decrement loops
+              5. Eliminated call to round by proper initialization
+
+ Description:  Added casting to eliminate warnings
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description: Added pOverflow as a passed in value to searchFrac and made
+              other fixes to the code regarding simple syntax fixes. Removed
+              the include of stio.h.
+
+ Description: *lag-- decrements the pointer.  (*lag)-- decrements what is
+ pointed to.  The latter is what the coder intended, but the former is
+ the coding instruction that was used.
+
+ Description: A common problem -- a comparison != 0 was inadvertantly replaced
+ by a comparison == 0.
+
+
+ Description:  For Norm_Corr() and getRange()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation, in some cases this by shifting before adding and
+                 in other cases by evaluating the operands
+              4. Unrolled loops to speed up processing, use decrement loops
+              5. Replaced extract_l() call with equivalent code
+              6. Modified scaling threshold and group all shifts (avoiding
+                 successive shifts)
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Removed compiler warnings.

+ FUNCTION DESCRIPTION
+
+  FUNCTION:   Norm_Corr()
+
+  PURPOSE: Find the normalized correlation between the target vector
+           and the filtered past excitation.
+
+  DESCRIPTION:
+     The normalized correlation is given by the correlation between the
+     target and filtered past excitation divided by the square root of
+     the energy of filtered excitation.
+                   corr[k] = <x[], y_k[]>/sqrt(y_k[],y_k[])
+     where x[] is the target vector and y_k[] is the filtered past
+     excitation at delay k.

+ FUNCTION DESCRIPTION
+
+ Find the lag that has maximum correlation of scal_sig in a given delay range.
+ The correlation is given by:
+
+         cor[t] = <scal_sig[n],scal_sig[n-t]>,  t=lag_min,...,lag_max
+
+ The function returns the maximum correlation after normalization and the
+ corresponding lag.

+ FUNCTION DESCRIPTION
+
+ This function computes the open loop pitch lag based on the perceptually
+ weighted speech signal. This is done in the following steps:
+       - find three maxima of the correlation <sw[n],sw[n-T]>,
+         dividing the search range into three parts:
+              pit_min ... 2*pit_min-1
+            2*pit_min ... 4*pit_min-1
+            4*pit_min ...   pit_max
+       - divide each maximum by <sw[n-t], sw[n-t]> where t is the delay at
+         that maximum correlation.
+       - select the delay of maximum normalized correlation (among the
+         three candidates) while favoring the lower delay ranges.

+ REVISION HISTORY
+
+ Description: Put the file into our template structure.
+
+ Description: First pass optimization.
+
+ Description: Made changes based on comments from review meeting.
+
+ Description: Synchronized file with UMTS version 3.2.0. Updated coding
+              template. Removed unnecessary include files.
+
+ Description: Removed basic_op.h from the Include section. It is not used.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Fixed typecasting issue with TI C compiler.
+              2. Modified FOR loop to count down.
+              3. Cosmetic changes to the code to make address post-increment
+                 clearer.
+              4. Removed unnecessary typecasting in the multiply-accumulate
+                 portion of FOR loop body.
+              5. Removed "static" in table definitions.
+              6. Updated copyright year.
+
+ Description:  For Pre_Process()
+              1. Replaced variables (containing filter coefficients) with
+                 constants, to avoid extra register swaping.
+              2. Changed to decrement loop
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Eliminated math operations that unnecessary checked for
+                 saturation by evaluating the operands
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.

+ REVISION HISTORY
+
+ Description: Updated template used to PV coding template.
+ Changed to accept the pOverflow flag for EPOC compatibility.
+
+ Description:
+ (1) Removed optimization -- mult(i, 3, pOverflow) is NOT the same as adding
+     i to itself 3 times.  The reason is because the mult function does a
+     right shift by 15, which will obliterate smaller numbers.
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.
+
+ Description: Added #ifdef __cplusplus around extern'ed table.

+ REVISION HISTORY
+
+ Description: Adding pOverflow to the functions to remove global variables.
+              These changes are needed for the EPOC releases. Cleaned up code.
+              Updated template.
+
+ Description: Changed temp to temp32. When temp was only 16 bits it was not
+              holding the 32 bit value returned from the functions. Some
+              variables were also being declared as Word16 rather than Word32
+              as they were suposed to be.
+
+ Description: Changed copyright year. Removed all calls to math functions by
+              inlining them, and removed all unnecessary files in the Include
+              section.
+
+ Description: Made the following changes per comments from Phase 2/3 review:
+              1. Removed all #defines.
+              2. Used a pointer to &codvec[0] instead of array indexing.
+              3. Removed multiple data casting in the code.
+
+ Description:
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers, this by taking
+                 advantage of the fact that the autocrrelation  matrix is
+                 a toeplitz matrix, so r[i][j] = r[j][i], then a single
+                 pointer can be used to address a matrix. The use of this
+                 is not uniform along the function (due to compiler limitations:
+                 handling so many variables in this file) so the use
+                 of this is pointer optimizations is limited to places
+                 where the ARM compiler provides the lesses numer of cycles
+              3. Eliminated use of intermediate variables to accelerate
+                 comparisons (like in the nested loops)
+              4. Introduced array temp1[], to pre-calculate the elements
+                 used in the nested loops, in this way the calculation is
+                 not repeated in every loop iteration. This is done for
+                 loops i3-i5-i7 and i9
+              5. Use array Index[] to store indexes i1:i9, and then use memcpy
+                 to update indexes.
+              6. Eliminated shifts by modifying the way number are rounded,
+                 this does not have any effect in ARM processors but may help
+                 other compilers
+
+ Description:
+              1. When storing indexes, added memcpy() to support the rates
+                 that use this function: 12.2 (already done) and 10.2 (missing).
+
+ Description:  Replaced OSCL mem type functions and eliminated include
+               files that now are chosen by OSCL definitions
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+              1. Modified certain FOR loops to count down.
+              2. Modified code for further optimization.
+
+ Description: Modified FOR loops in set_sign12k2 to count up. The FOR loops
+              affected are the loop that calculates the starting position of
+              each incoming pulse, and the loop that calculates the position
+              of the max correlation. Updated copyright year.
+
+ Description: Passing in pointer to overflow flag for EPOC compatibility.
+
+ Description:  For set_sign12k2()
+              1. Eliminated unused include files.
+              2. Replaced array addressing by pointers
+              3. Eliminated math operations that unnecessary checked for
+                 saturation, this by evaluating the operands
+              4. Replaced loop counter with decrement loops
+
+ Description:  Replaced "int" and/or "char" with OSCL defined types.
+
+ Description: Changed round function name to pv_round to avoid conflict with
+              round function in C standard library.

+ FUNCTION DESCRIPTION
+
+ This function is the entry point to the GSM AMR encoder. The following
+ operations are performed to generate one encoded frame: First, the incoming
+ audio samples are passed through the pre-processing filter where they are
+ filtered and downscaled. A call is then made to the main encoder cod_amr().
+ This generates the set of encoded parameters which include the LSP, adaptive
+ codebook, and fixed codebook quantization indices (addresses and gains). The
+ generated parameters are then converted to serial bits.

+
+    mult_int16_r()     : Same as mult_int16 with rounding
+    shr_rnd()          : Same as shr(var1,var2) but with rounding
+    div_16by16()       : fractional integer division
+    one_ov_sqrt()      : Compute 1/sqrt(L_x)
+    one_ov_sqrt_norm() : Compute 1/sqrt(x)
+    power_of_2()       : power of 2
+    Dot_product12()    : Compute scalar product of <x[],y[]> using accumulator
+    Isqrt()            : inverse square root (16 bits precision).
+    amrwb_log_2()      : log2 (16 bits precision).
+
+    These operations are not standard double precision operations.
+    They are used where low complexity is important and the full 32 bits
+    precision is not necessary. For example, the function Div_32() has a
+    24 bits precision which is enough for our purposes.
+
+    In this file, the values use theses representations:
+
+    int32 L_32     : standard signed 32 bits format
+    int16 hi, lo   : L_32 = hi<<16 + lo<<1  (DPF - Double Precision Format)
+    int32 frac, int16 exp : L_32 = frac << exp-31  (normalised format)
+    int16 int, frac        : L_32 = int.frac        (fractional format)

+ *       Since the LSB's also contain a sign bit, this format does not       *
+ *       correspond to standard 32 bit integers.  We use this format since   *
+ *       it allows fast execution of multiplications and divisions.          *

+ *       The R[i] were normalized in routine AUTO (hence, R[i] < 1.0).       *
+ *       The K[i] and Alpha are theoretically < 1.0.                         *
+ *       The A[i], for a sampling frequency of 8 kHz, are in practice        *
+ *       always inferior to 16.0.                                            *

+ *               Alpha   Normalized -> mantissa in Q31 plus exponent         *
+ *               A[i]    Q27   +- 15.999..                                   *

+ *       The additions are performed in 32 bit.  For the summation used      *
+ *       to calculate the K[i], we multiply numbers in Q31 by numbers        *
+ *       in Q27, with the result of the multiplications in Q27,              *
+ *       resulting in a dynamic of +- 16.  This is sufficient to avoid       *
+ *       overflow, since the final result of the summation is                *
+ *       necessarily < 1.0 as both the K[i] and Alpha are                    *

+        that are used in the filter algorithm.
+    x_blk_start = value of the x coordinate of type int that specifies the
+        column of pixels which contains the start of a block.  The

+ FUNCTION DESCRIPTION
+
+ This function implements a motion compensated noise filter using adaptive
+ weighted averaging of luminance values.  *Rec_Y contains the luminance values
+ that are being filtered.
+
+ The picture below depicts a 3x3 group of pixel luminance values.  The "u", "c",
+ and "l" stand for "upper", "center" and "lower", respectively.  The location
+ of pelc0 is specified by x_start and y_start in the 1-D array "Rec_Y" as
+ follows (assuming x_start=0):
+
+ location of pelc0 = [(y_start+1) * width] + x_start
+
+ Moving up or down 1 row (moving from pelu2 to pelc2, for example) is done by
+ incrementing or decrementing "width" elements within Rec_Y.
+
+ The coordinates of the upper left hand corner of a block (not the group of
+ 9 pixels depicted in the figure below) is specified by
+ (y_blk_start, x_blk_start).  The width and height of the block is BLKSIZE.
+ (y_start,x_start) may be specified independently of (y_blk_start, x_blk_start).
+
+    (y_start,x_start)
+ -----------|--------------------------
+    |   |   |   |   |
+    |   X   | pelu1 | pelu2 |
+    | pelu0 |   |   |
+    |   |   |   |
+ --------------------------------------
+    |   |   |   |
+    | pelc0 | pelc1 | pelc2 |

+    | pell0 | pell1 | pell2 |
+    |   |   |   |
+    |   |   |   |
+ --------------------------------------
+
+ The filtering of the luminance values is achieved by comparing the 9
+ luminance values to a threshold value ("thr") and then changing the
+ luminance value of pelc1 if all of the values are above or all of the values
+ are below the threshold.  The amount that the luminance value is changed
+ depends on a weighted sum of the 9 luminance values. The position of Pelc1
+ is then advanced to the right by one (as well as all of the surrounding pixels)
+ and the same calculation is performed again for the luminance value of the new
+ Pelc1. This continues row-wise until pixels in the last row of the block are
+ filtered.

+ FUNCTION DESCRIPTION
+
+ This function finds the maximum and the minimum values in a square block of
+ data of size BLKSIZE * BLKSIZE. The data is contained in the buffer which
+ represents a 2D block of data that is larger than BLKSIZE * BLKSIZE.
+ This is illustrated below.
+
+    mem loc x + 00h -> o o o o o o o o o o o o o o o o
+    mem loc x + 10h -> o o o o o X X X X X X X X o o o
+    mem loc x + 20h -> o o o o o X X X X X X X X o o o
+    mem loc x + 30h -> o o o o o X X X X X X X X o o o
+    mem loc x + 40h -> o o o o o X X X X X X X X o o o
+    mem loc x + 50h -> o o o o o X X X X X X X X o o o
+    mem loc x + 60h -> o o o o o X X X X X X X X o o o
+    mem loc x + 70h -> o o o o o X X X X X X X X o o o
+    mem loc x + 80h -> o o o o o X X X X X X X X o o o
+    mem loc x + 90h -> o o o o o o o o o o o o o o o o
+    mem loc x + A0h -> o o o o o o o o o o o o o o o o
+    mem loc x + B0h -> o o o o o o o o o o o o o o o o
+
+For illustration purposes, the diagram assumes that BLKSIZE is equal to 8
+but this is not a requirement. In this diagram, the buffer starts at
+location x but the input pointer, input_ptr, passed into this function
+would be the first row of data to be searched which is at x + 15h. The
+value of incr passed onto this function represents the amount the input_ptr
+needs to be incremented to point to the next row of data.
+
+This function compares each value in a row to the current maximum and
+minimum. After each row, input_ptr is incremented to point to the next row.
+This is repeated until all rows have been processed. When the search is
+complete the location pointed to by min_ptr contains the minimum value
+found and the location pointed to by max_ptr contains the maximum value found.

+ FUNCTION DESCRIPTION
+
+ Summary:
+
+ This function performs motion compensated prediction for the case where
+ the motion vector points to a block outside the VOP. The function interpolates
+ the pixels that are outside the VOP using the boundary pixels for the block.
+ Once the values are interpolated, the pixel values are computed for a block
+ in the current VOP. The prediction values are generated by averaging pixel
+ values in the previous VOP; the block position in the previous frame is
+ computed from the current block's motion vector. The computed pixel values
+ are calculated by adding the prediction values to the block residual values.
+
+ Details:
+
+ First, this functions determines which VOP boundary(ies) the motion vector
+ is outside, i.e., left, right, top, bottom. xpos is compared to the left and
+ right boundaries; ypos is compared to the top and bottom boundaries. The number
+ of block pixels inside the the boundary in the x and y directions are stored
+ in endx and endy, respectively. If the entire block is inside the x or y
+ boundary, the respectively end is set to 0.
+
+ After the boundaries are tested, any pixels lying outside a boundary are
+ interpolated from the boundary pixels. For example, if the block is outside the
+ bottom boundary, boundary pixels alone the bottom of the VOP as used to
+ interpolated those pixels lying outside the bottom boundary. The interpolation
+ used is a simple column-wise or row-wise copy of the boundary pixels (inside the
+ block) depending on which boundary the block is outside. In our example, each
+ boundary pixel would be copied column-wise to the pixel beneath it. If the
+ block was outside right boundary, the boundary pixels would be copied row-wise
+ to the pixel to the right of it. If the block was outside both an x and y
+ boundary, the boundary pixels would be copied row-wise for the portion of the
+ block outside the x boundary, and column-wise for the portion of the block
+ outside the y boundary. And so on.
+
+ Once the pixel interpolation is complete, the motion compensated output values
+ (comp[]) are calculed from the motion compensated prediction (pred[])values and
+ the residual values (sh_d[]) of the current frame. The prediction values are
+ generated by averaging pixel values in the previous VOP; the block position in
+ the previous frame is computed from the current block's motion vector. The
+ computed pixel values are calculated by adding the prediction values to the
+ block residual values.

+          coefficients of type int for an 8r8 image block;
+          values range from (-2048, 2047) which defined as standard.

+ FUNCTION DESCRIPTION FOR idct
+
+ This function transforms an 8r8 image block from dequantized DCT coefficients
+ (F(u,v)) to spatial domain pirel values (f(r,y)) by performing the two
+ dimensional inverse discrete cosine transform (IDCT).
+
+         _7_ _7_      C(u) C(v)
+    f(r,y) = \   \  F(u,v)---- ----cos[(2r+1)*u*pi/16]cos[(2y+1)*v*pi/16]
+         /__ /__    2    2
+         u=0 v=0
+
+    where   C(i) = 1/sqrt(2)    if i=0
+        C(i) = 1        otherwise
+
+ 2-D IDCT can be separated as horizontal(row-wise) and vertical(column-wise)
+ 1-D IDCTs. Therefore, 2-D IDCT values are found by the following two steps:
+ 1. Find horizontal 1-D IDCT values for each row from 8r8 dequantized DCT
+    coefficients by row IDCT operation.
+
+          _7_        C(u)
+    g(r,v) =  \   F(u,v) ---- cos[(2r+1)*u*pi/16]
+          /__         2
+          u=0
+
+ 2. Find vertical 1-D IDCT values for each column from the results of 1
+    by column IDCT operation.
+
+              _7_        C(v)
+    f(r,y) =  \   g(r,v) ---- cos[(2y+1)*v*pi/16]
+          /__         2
+          v=0

+ FUNCTION DESCRIPTION
+
+ This function performs high level motion compensation on the luminance and
+ chrominance data. It sets up all the parameters required by the functions
+ that perform luminance and chrominance prediction and it initializes the
+ pointer to the post processing semaphores of a given block. It also checks
+ the motion compensation mode in order to determine which luminance or
+ chrominance prediction functions to call and determines how the post
+ processing semaphores are updated.

+ FUNCTION DESCRIPTION
+
+ This function sets up the postmode semaphore based on the contents of the
+ buffer pointed to by q_block. The function starts out with the assumption
+ that all entries of q_block, except for the first entry (q_block[0]), are
+ zero. This case can induce horizontal and vertical blocking artifacts,
+ therefore, both horizontal and vertical deblocking bits are enabled.
+
+ The following conditions are tested when setting up the horizontal/vertical
+ deblocking and deringing bits:
+ 1. When only the elements of the top row of the B_SIZE x B_SIZE block
+    (q_block[n], n = 0,..., B_SIZE-1) are non-zero, vertical blocking artifacts
+    may result, therefore, only the vertical deblocking bit is enabled.
+    Otherwise, the vertical deblocking bit is disabled.
+ 2. When only the elements of the far left column of the B_SIZE x B_SIZE block
+    (q_block[n*B_SIZE], n = 0, ..., B_SIZE-1) are non-zero, horizontal blocking
+    artifacts may result, therefore, only the horizontal deblocking bit is
+    enabled. Otherwise, the horizontal deblocking bit is disabled.
+ 3. If any non-zero elements exist in positions other than q_block[0],
+    q_block[1], or q_block[B_SIZE], the deringing bit is enabled. Otherwise,
+    it is disabled.
+
+ The 3 least significant bits of postmode defines vertical or horizontal
+ deblocking and deringing.
+
+ The valid values are shown below:
+ -------------------------------------------------------
+ |           Type                 | Enabled | Disabled |
+ -------------------------------------------------------
+ | Vertical Deblocking (Bit #0)   |    1    |     0    |
+ -------------------------------------------------------
+ | Horizontal Deblocking (Bit #1) |    1    |     0    |
+ -------------------------------------------------------
+ | Deringing (Bit #2)             |    1    |     0    |

+/** @introduction   Common Video Encoder Interface (CVEI) is intended to be used by
+    application developers who want to create a multimedia application with video
+    encoding feature. CVEI is designed such that new video encoder algorithms or
+    modules can be plugged in seamlessly without user interaction. In other words,
+    any changes to the CVEI library are transparent to the users. Users can still
+    use the same set of APIs for new encoding tools.
+
+    @requirement    CVEI will take an input frame in one of several format supported
+    by PV and encode it to an MPEG4 bitstream. It will also return a reconstructed
+    image in YUV 4:2:0 format. Currently the input format supported are YUV 4:2:0,
+    RGB24 and UYVY 4:2:2.
+
+    CVEI is designed such that it is simple to use. It should hides implementation
+    dependency  from the users. In this version, we decided that the operation will
+    be synchronous, i.e., the encoding will be a blocked call. Asynchronous operation
+    will be in the level above CVEI, i.e., in Author Engine Video Module which will
+    take care of capturing device as well.
+
+    @brief  The following classes are used to interface with codecs. Their names
+    are CPVxxxVideoEncoder where xxx is codec specific such as MPEG4, H263, H26L,
+    etc. All of them are subclasses of CPVCommonVideoEncoder.

+ REVISION HISTORY
+ Who:   Date: July/2001
+ Description:   1. Optimized BlockIDCT bitmap checking.
+                2. Rearranged functions.
+                3. Do column IDCT first, then row IDCT.
+                4. Combine motion comp and IDCT, require
+                   two sets of row IDCTs one for INTRA
+                   and one for INTER.
+                5. Add AAN IDCT
+
+ Who:   Date: 8/16/01
+                1. Increase the input precision to 8 bits, i.e. change RDCTBITS
+                   to 11, have to comment out all in-line assembly since 16 bit
+                    multiplication doesn't work. Try to use diffent precision with
+                    32 bit mult. but hasn't finished. Turns out that without in-line
+                    assembly the performance doesn't change much (only 1%).
+ Who:   Date: 9/04/05
+                1. Replace AAN IDCT with Chen's IDCT to accommodate 16 bit data type.

+ Function: BlckQuantDequantH263
+ Date:     June 15, 1999
+ Purpose:  Combine BlockQuantH263 and BlockDequantH263ENC
+ Input:   coeff=> DCT coefficient
+ Output:  qcoeff=> quantized coefficient
+          rcoeff=> reconstructed coefficient
+          return CBP for this block
+          4/2/01,  correct dc_scaler for short_header mode.
+          5/14/01,
+          changed the division into LUT multiplication/shift and other
+          modifications to speed up fastQuant/DeQuant (check for zero 1st, rowq LUT,
+          fast bitmaprow mask and borrowed Addition method instead of ifs from , ).
+          6/25/01,
+          Further optimization (~100K/QCIF), need more testing/comment before integration.
+
+          7/4/01,  break up Inter / Intra function and merge for different cases.
+          7/22/01,  combine AAN scaling here and reordering.
+          7/24/01, , reorder already done in FDCT, the input here is in the next block and
+            it's the
+            transpose of the raster scan. Output the same order (for proof of concenpt).
+          8/1/01, , change FDCT to do row/column FDCT without reordering, input is still
+            in the next block. The reconstructed DCT output is current block in normal
+            order. The quantized output is in zigzag scan order for INTER, row/column for
+            INTRA. Use bitmapzz for zigzag RunLevel for INTER.  The quantization is done
+            in column/row scanning order.
+          8/2/01, , change IDCT to do column/row, change bitmaprow/col to the opposite.
+          8/3/01, , add clipping to the reconstructed coefficient [-2047,2047]
+          9/4/05, , removed scaling for AAN IDCT, use Chen IDCT instead.

+ Function: BlckQuantDequantMPEG
+ Date:     June 15, 1999
+ Purpose:  Combine BlockQuantMPEG and BlockDequantMPEGENC
+ Input:   coeff=> DCT coefficient
+ Output:  qcoeff=> quantized coefficient
+          rcoeff=> reconstructed coefficient
+ Modified:  7/5/01, break up function for Intra/Inter
+          8/3/01,  update with changes from H263 quant mode.
+          8/3/01,  add clipping to the reconstructed coefficient [-2048,2047]
+          8/6/01,  optimize using multiplicative lookup-table.
+                     can be further optimized using ARM assembly, e.g.,
+                     clipping, 16-bit mult., etc !!!!!!!!!!!!!

+
+Input
+    pExt = pointer to the external interface structure. See the file
+           pvmp3decoder_api.h for a description of each field.
+           Data type of pointer to a tPVMP3DecoderExternal
+           structure.
+
+    pMem = void pointer to hide the internal implementation of the library
+           It is cast back to a tmp3dec_file structure. This structure
+           contains information that needs to persist between calls to
+           this function, or is too big to be placed on the stack, even
+           though the data is only needed during execution of this function
+           Data type void pointer, internally pointer to a tmp3dec_file
+           structure.
+
+
+ Outputs:
+     status = ERROR condition.  see structure  ERROR_CODE
+
+ Pointers and Buffers Modified:
+    pMem contents are modified.
+    pExt: (more detail in the file pvmp3decoder_api.h)

+ FUNCTION DESCRIPTION
+
+    The frequency lines are preprocessed by the "alias reduction" scheme
+    and fed into the IMDCT matrix, each 18 into one transform block.
+    The first half of the output values are added to the stored overlap
+    values from the last block. These values are new output values and
+    are input values for the polyphase filterbank. The second half of the
+    output values is stored for overlap with the next data granule.
+    The number of windowed samples is 12 for short blocks, and 36 for long
+    blocks
+
+Windowing
+
+    Depending on window_switching_flag[gr][ch], block_type[gr][ch] and
+    mixed_block_flag[gr][ch] different shapes of windows are used.
+        normal window
+        start window
+        stop window
+        short windows
+            Each of the three short blocks is windowed separately.
+            The windowed short blocks must be overlapped and concatenated.
+
+Overlapping and adding with previous block
+
+    The first half (18 values) of the current block (36 values) has to be
+    overlapped with the second half of the previous block. The second half
+    of the current block has to be stored for overlapping with the next block

+ FUNCTION DESCRIPTION
+
+    stereo processing for mpeg1 layer III
+    After requantization, the reconstructed values are processed for ms_stereo
+    or intensity_stereo modes or both, before passing them to the synthesis
+    filterbank
+
+    In ms_stereo mode the values of the normalized middle/side channels
+    M[l] and S[l] are transmitted instead of the left/right channel values
+    L[l] and R[l]. From here, L[l] and R[l] are reconstructed
+
+    Intensity_stereo is done by specifying the magnitude (via the
+    scalefactors of the left channel) and a stereo position is_pos[sfb],
+    which is transmitted instead of scalefactors of the right channel.
+    The stereo position is used to derive the left and right channel signals

+This transaction contains deliverables which are designated as being of
+beta release status (BET).
+
+Beta release status has a particular meaning to ARM of which the recipient
+must be aware. Beta is a pre-release status indicating that the deliverable
+so described is believed to robustly demonstrate specified behaviour, to be
+consistent across its included aspects and be ready for general deployment.
+But Beta also indicates that pre-release reliability trials are ongoing and
+that it is possible residual defects or errors in operation, consistency
+and documentation may still be encountered. The recipient should consider
+this position when using this Beta material supplied. ARM will normally
+attempt to provide fixes or a work-around for defects identified by the
+recipient, but the provision or timeliness of this support cannot be
+guaranteed. ARM shall not be responsible for direct or consequential
+damages as a result of encountering one or more of these residual defects.
+By accepting a Beta release, the recipient agrees to these constraints and
+to providing reasonable information to ARM to enable the replication of the
+defects identified by the recipient. The specific Beta version supplied
+will not be supported after release of a later or higher status version.
+It should be noted that Support for the Beta release of the deliverable
+will only be provided by ARM to a recipient who has a current support and
+maintenance contract for the deliverable.

+;// OpenMAX optimized bitstream decode module
+;//
+;// You must include armCOMM_s.h before including this file
+;//
+;// This module provides macros to perform assembly optimized fixed and
+;// variable length decoding from a read-only bitstream. The variable
+;// length decode modules take as input a pointer to a table of 16-bit
+;// entries of the following format.
+;//
+;// VLD Table Entry format
+;//
+;//        15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
+;//       +------------------------------------------------+
+;//       |  Len   |               Symbol              | 1 |
+;//       +------------------------------------------------+
+;//       |                Offset                      | 0 |
+;//       +------------------------------------------------+
+;//
+;// If the table entry is a leaf entry then bit 0 set:
+;//    Len    = Number of bits overread (0 to 7)
+;//    Symbol = Symbol payload (unsigned 12 bits)
+;//
+;// If the table entry is an internal node then bit 0 is clear:
+;//    Offset = Number of (16-bit) half words from the table
+;//             start to the next table node
+;//
+;// The table is accessed by successive lookup up on the
+;// next Step bits of the input bitstream until a leaf node
+;// is obtained. The Step sizes are supplied to the VLD macro.
+;//
+;// USAGE:
+;//
+;// To use any of the macros in this package, first call:
+;//
+;//    M_BD_INIT ppBitStream, pBitOffset, pBitStream, RBitBuffer, RBitCount, Tmp
+;//
+;// This caches the current bitstream position and next available
+;// bits in registers pBitStream, RBitBuffer, RBitCount. These registers
+;// are reserved for use by the bitstream decode package until you
+;// call M_BD_FINI.
+;//
+;// Next call the following macro(s) as many times as you need:
+;//
+;//    M_BD_LOOK8       - Look ahead constant 1<=N<=8  bits into the bitstream
+;//    M_BD_LOOK16      - Look ahead constant 1<=N<=16 bits into the bitstream
+;//    M_BD_READ8       - Read constant 1<=N<=8  bits from the bitstream
+;//    M_BD_READ16      - Read constant 1<=N<=16 bits from the bitstream
+;//    M_BD_VREAD8      - Read variable 1<=N<=8  bits from the bitstream
+;//    M_BD_VREAD16     - Read variable 1<=N<=16 bits from the bitstream
+;//    M_BD_VLD         - Perform variable length decode using lookup table
+;//
+;// Finally call the macro:
+;//
+;//    M_BD_FINI ppBitStream, pBitOffset
+;//
+;// This writes the bitstream state back to memory.
+;//
+;// The three bitstream cache register names are assigned to the following global
+;// variables:
+;//
+
+        GBLS    pBitStream  ;// Register name for pBitStream
+        GBLS    BitBuffer   ;// Register name for BitBuffer
+        GBLS    BitCount    ;// Register name for BitCount
+   
+;//        
+;// These register variables must have a certain defined state on entry to every bitstream
+;// macro (except M_BD_INIT) and on exit from every bitstream macro (except M_BD_FINI).
+;// The state may depend on implementation.
+;//
+;// For the default (ARM11) implementation the following hold:
+;//    pBitStream - points to the first byte not held in the BitBuffer
+;//    BitBuffer  - is a cache of (4 bytes) 32 bits, bit 31 the first bit
+;//    BitCount   - is offset (from the top bit) to the next unused bitstream bit
+;//    0<=BitCount<=15 (so BitBuffer holds at least 17 unused bits)
+;//
+;//
+
+        ;// Bitstream Decode initialise
+        ;//
+        ;// Initialises the bitstream decode global registers from
+        ;// bitstream pointers. This macro is split into 3 parts to enable
+        ;// scheduling.

+;// ALGORITHM DESCRIPTION
+;//
+;// The 8x8 2D IDCT is performed by calculating a 1D IDCT for each
+;// column and then a 1D IDCT for each row.
+;//
+;// The 8-point 1D IDCT is defined by
+;//   f(x) = (C(0)*T(0)*c(0,x) + ... + C(7)*T(7)*c(7,x))/2
+;//
+;//   C(u) = 1/sqrt(2) if u=0 or 1 if u!=0
+;//   c(u,x) = cos( (2x+1)*u*pi/16 )
+;//
+;// We compute the 8-point 1D IDCT using the reverse of
+;// the Arai-Agui-Nakajima flow graph which we split into
+;// 5 stages named in reverse order to identify with the
+;// forward DCT. Direct inversion of the forward formulae
+;// in file FDCT_s.s gives:
+;//
+;// IStage 5:   j(u) = T(u)*A(u)  [ A(u)=4*C(u)*c(u,0) ]

+;// 2. The flowgraph in the AAN paper has h4,g6 negated compared
+;//    to the above code but is otherwise identical.
+;// 3. The rotation by -pi/8 can be peformed using three multiplies

+;//       -s*i4+c*i6 = (i6-i4)*s + (c-s)*i6

+;//            = ((1/sqrt2) + cos(pi/16) + ... + cos(7*pi/16))/2
+;//            = ((1/sqrt2) + (cot(pi/32)-1)/2)/2

+ *
+ * This file allows a version of the OMX DL libraries to be built where some or
+ * all of the function names can be given a user specified suffix. 
+ *
+ * You might want to use it where:
+ *
+ * - you want to rename a function "out of the way" so that you could replace
+ *   a function with a different version (the original version would still be
+ *   in the library just with a different name - so you could debug the new
+ *   version by comparing it to the output of the old)
+ *
+ * - you want to rename all the functions to versions with a suffix so that 
+ *   you can include two versions of the library and choose between functions
+ *   at runtime.
+ *
+ *     e.g. omxIPBM_Copy_U8_C1R could be renamed omxIPBM_Copy_U8_C1R_CortexA8

+ *
+ * Description:
+ * This function extracts run-length encoding (RLE) information from the 
+ * coefficient matrix.  The results are returned in an OMXVCM4P10VLCInfo 
+ * structure. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcCoeff - pointer to the transform coefficient matrix.  8-byte 
+ *            alignment required. 
+ *   pScanMatrix - pointer to the scan order definition matrix.  For a luma 
+ *            block the scan matrix should follow [ISO14496-10] section 8.5.4, 
+ *            and should contain the values 0, 1, 4, 8, 5, 2, 3, 6, 9, 12, 13, 
+ *            10, 7, 11, 14, 15.  For a chroma block, the scan matrix should 
+ *            contain the values 0, 1, 2, 3. 
+ *   bAC - indicates presence of a DC coefficient; 0 = DC coefficient 
+ *            present, 1= DC coefficient absent. 
+ *   MaxNumCoef - specifies the number of coefficients contained in the 
+ *            transform coefficient matrix, pSrcCoeff. The value should be 16 
+ *            for blocks of type LUMADC, LUMAAC, LUMALEVEL, and CHROMAAC. The 
+ *            value should be 4 for blocks of type CHROMADC. 
+ *
+ * Output Arguments:
+ *   
+ *   pDstVLCInfo - pointer to structure that stores information for 
+ *            run-length coding. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments; returned if any of the following 
+ *              conditions are true: 
+ *    -    at least one of the following pointers is NULL: 
+ *            pSrcCoeff, pScanMatrix, pDstVLCInfo

+; *
+; * Description:
+; * Performs VLC decoding and inverse zigzag scan for one inter coded block.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in]    ppBitStream        pointer to the pointer to the current byte in
+; *                    the bitstream buffer
+; * [in]    pBitOffset        pointer to the bit position in the byte pointed
+; *                    to by *ppBitStream. *pBitOffset is valid within    [0-7].
+; * [in] shortVideoHeader     binary flag indicating presence of short_video_header;
+; *                           escape modes 0-3 are used if shortVideoHeader==0,
+; *                           and escape mode 4 is used when shortVideoHeader==1.
+; * [out]    ppBitStream        *ppBitStream is updated after the block is
+; *                    decoded, so that it points to the current byte
+; *                    in the bit stream buffer
+; * [out]    pBitOffset        *pBitOffset is updated so that it points to the
+; *                    current bit position in the byte pointed by
+; *                    *ppBitStream
+; * [out]    pDst            pointer to the coefficient buffer of current
+; *                    block. Must be 16-byte aligned
+; *
+; * Return Value:
+; * OMX_Sts_BadArgErr - bad arguments
+; *   -At least one of the following pointers is NULL: ppBitStream, *ppBitStream, pBitOffset, pDst, or
+; *   -pDst is not 16-byte aligned, or
+; *   -*pBitOffset exceeds [0,7].
+; * OMX_Sts_Err - status error
+; *   -At least one mark bit is equal to zero
+; *   -Encountered an illegal stream code that cannot be found in the VLC table
+; *   -Encountered and illegal code in the VLC FLC table
+; *   -The number of coefficients is greater than 64

+    ;// different macro calls. PreLoading is used to avoid reload of same data. 
+    ;// 
+    ;// Filtering involves averaging a pixel with the next vertical, horizontal 
+    ;// and right-down diagonal pixels. Just as in HalfPixelX case, M_LOAD_XINT
+    ;// and M_EXT_XINT combination generates 4 registers with a row and its
+    ;// 1 pixel right shifted version, with 4 pixels in one register. Another 
+    ;// call of that macro-combination gets another row. Then M_HSUM_XOR is 
+    ;// called to get mutual half-sum and xor combinations of a row with its
+    ;// shifted version as they are inputs to the M_AVG4 macro which computes
+    ;// the 4 element average with rounding. Note that it is the half-sum/xor 
+    ;// values that are preserved for next row as they can be re-used in the 
+    ;// next call to the M_AVG4 and saves recomputation.
+    ;// Due to lack of register, the row counter and a masking value required 
+    ;// in M_AVG4 are packed into a single register yMask where the last nibble
+    ;// holds the row counter values and rest holds the masking variable left

+; * 
+; * 
+; * 
+; * Description:
+; * Contains module for DC/AC coefficient prediction
+; *
+; * 
+; * Function: omxVCM4P2_PredictReconCoefIntra
+; *
+; * Description:
+; * Performs adaptive DC/AC coefficient prediction for an intra block. Prior
+; * to the function call, prediction direction (predDir) should be selected
+; * as specified in subclause 7.4.3.1 of ISO/IEC 14496-2.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in]  pSrcDst      pointer to the coefficient buffer which contains the 
+; *                    quantized coefficient residuals (PQF) of the current 
+; *                    block; must be aligned on a 4-byte boundary. The 
+; *                    output coefficients are saturated to the range 
+; *                    [-2048, 2047].
+; * [in]  pPredBufRow  pointer to the coefficient row buffer; must be aligned
+; *                    on a 4-byte boundary.
+; * [in]  pPredBufCol  pointer to the coefficient column buffer; must be 
+; *                    aligned on a 4-byte boundary.
+; * [in]  curQP        quantization parameter of the current block. curQP may 
+; *                    equal to predQP especially when the current block and 
+; *                    the predictor block are in the same macroblock.
+; * [in]  predQP       quantization parameter of the predictor block
+; * [in]  predDir      indicates the prediction direction which takes one
+; *                    of the following values:
+; *                    OMX_VIDEO_HORIZONTAL    predict horizontally
+; *                    OMX_VIDEO_VERTICAL        predict vertically
+; * [in]  ACPredFlag   a flag indicating if AC prediction should be
+; *                    performed. It is equal to ac_pred_flag in the bit
+; *                    stream syntax of MPEG-4
+; * [in]  videoComp    video component type (luminance, chrominance or
+; *                    alpha) of the current block
+; * [out] pSrcDst      pointer to the coefficient buffer which contains
+; *                    the quantized coefficients (QF) of the current
+; *                    block
+; * [out] pPredBufRow  pointer to the updated coefficient row buffer
+; * [out] pPredBufCol  pointer to the updated coefficient column buffer
+; * Return Value:
+; * OMX_Sts_NoErr - no error
+; * OMX_Sts_BadArgErr - Bad arguments 
+; * - At least one of the pointers is NULL: pSrcDst, pPredBufRow, or pPredBufCol.
+; * - At least one the following cases: curQP <= 0, predQP <= 0, curQP >31, 
+; *   predQP > 31, preDir exceeds [1,2].
+; * - At least one of the pointers pSrcDst, pPredBufRow, or pPredBufCol is not 
+; *   4-byte aligned.

+; * 
+; * File Name:  omxVCM4P2_QuantInvInter_I_s.s
+; * OpenMAX DL: v1.0.2
+; * Revision:   9641
+; * Date:       Thursday, February 7, 2008
+; * 
+; * (c) Copyright 2007-2008 ARM Limited. All Rights Reserved.
+; * 
+; * 
+; *
+; * Description: 
+; * Contains modules for inter reconstruction
+; * 
+; *
+; *
+; *
+; *
+; * Function: omxVCM4P2_QuantInvInter_I
+; *
+; * Description:
+; * Performs inverse quantization on intra/inter coded block.
+; * This function supports bits_per_pixel = 8. Mismatch control
+; * is performed for the first MPEG-4 mode inverse quantization method.
+; * The output coefficients are clipped to the range: [-2048, 2047].
+; * Mismatch control is performed for the first inverse quantization method.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in] pSrcDst          pointer to the input (quantized) intra/inter block. Must be 16-byte aligned.
+; * [in] QP              quantization parameter (quantiser_scale)
+; * [in] videoComp      (Intra version only.) Video component type of the
+; *                  current block. Takes one of the following flags:
+; *                  OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE,
+; *                  OMX_VC_ALPHA.
+; * [in] shortVideoHeader a flag indicating presence of short_video_header;
+; *                       shortVideoHeader==1 selects linear intra DC mode,
+; *                  and shortVideoHeader==0 selects nonlinear intra DC mode.
+; * [out]    pSrcDst      pointer to the output (dequantized) intra/inter block.  Must be 16-byte aligned.
+; *
+; * Return Value:
+; * OMX_Sts_NoErr - no error
+; * OMX_Sts_BadArgErr - bad arguments
+; *    - If pSrcDst is NULL or is not 16-byte aligned.
+; *      or
+; *    - If QP <= 0.
+; *      or
+; *    - videoComp is none of OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE and OMX_VC_ALPHA.

+; *
+; *
+; *
+; *
+; * 
+; * Function: omxVCM4P2_QuantInvIntra_I
+; *
+; * Description:
+; * Performs inverse quantization on intra/inter coded block.
+; * This function supports bits_per_pixel = 8. Mismatch control
+; * is performed for the first MPEG-4 mode inverse quantization method.
+; * The output coefficients are clipped to the range: [-2048, 2047].
+; * Mismatch control is performed for the first inverse quantization method.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in]    pSrcDst        pointer to the input (quantized) intra/inter block. Must be 16-byte aligned.
+; * [in]    QP            quantization parameter (quantiser_scale)
+; * [in]    videoComp          (Intra version only.) Video component type of the
+; *                    current block. Takes one of the following flags:
+; *                    OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE,
+; *                    OMX_VC_ALPHA.
+; * [in]    shortVideoHeader  a flag indicating presence of short_video_header;
+; *                           shortVideoHeader==1 selects linear intra DC mode,
+; *                    and shortVideoHeader==0 selects nonlinear intra DC mode.
+; * [out]    pSrcDst        pointer to the output (dequantized) intra/inter block.  Must be 16-byte aligned.
+; *
+; * Return Value:
+; * OMX_Sts_NoErr - no error
+; * OMX_Sts_BadArgErr - bad arguments
+; *    -    If pSrcDst is NULL or is not 16-byte aligned.

+This transaction contains deliverables which are designated as being of
+beta release status (BET).
+
+Beta release status has a particular meaning to ARM of which the recipient
+must be aware. Beta is a pre-release status indicating that the deliverable
+so described is believed to robustly demonstrate specified behaviour, to be
+consistent across its included aspects and be ready for general deployment.
+But Beta also indicates that pre-release reliability trials are ongoing and
+that it is possible residual defects or errors in operation, consistency
+and documentation may still be encountered. The recipient should consider
+this position when using this Beta material supplied. ARM will normally
+attempt to provide fixes or a work-around for defects identified by the
+recipient, but the provision or timeliness of this support cannot be
+guaranteed. ARM shall not be responsible for direct or consequential
+damages as a result of encountering one or more of these residual defects.
+By accepting a Beta release, the recipient agrees to these constraints and
+to providing reasonable information to ARM to enable the replication of the
+defects identified by the recipient. The specific Beta version supplied
+will not be supported after release of a later or higher status version.
+It should be noted that Support for the Beta release of the deliverable
+will only be provided by ARM to a recipient who has a current support and
+maintenance contract for the deliverable.

+;// OpenMAX optimized bitstream decode module
+;//
+;// You must include armCOMM_s.h before including this file
+;//
+;// This module provides macros to perform assembly optimized fixed and
+;// variable length decoding from a read-only bitstream. The variable
+;// length decode modules take as input a pointer to a table of 16-bit
+;// entries of the following format.
+;//
+;// VLD Table Entry format
+;//
+;//        15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
+;//       +------------------------------------------------+
+;//       |  Len   |               Symbol              | 1 |
+;//       +------------------------------------------------+
+;//       |                Offset                      | 0 |
+;//       +------------------------------------------------+
+;//
+;// If the table entry is a leaf entry then bit 0 set:
+;//    Len    = Number of bits overread (0 to 7)
+;//    Symbol = Symbol payload (unsigned 12 bits)
+;//
+;// If the table entry is an internal node then bit 0 is clear:
+;//    Offset = Number of (16-bit) half words from the table
+;//             start to the next table node
+;//
+;// The table is accessed by successive lookup up on the
+;// next Step bits of the input bitstream until a leaf node
+;// is obtained. The Step sizes are supplied to the VLD macro.
+;//
+;// USAGE:
+;//
+;// To use any of the macros in this package, first call:
+;//
+;//    M_BD_INIT ppBitStream, pBitOffset, pBitStream, RBitBuffer, RBitCount, Tmp
+;//
+;// This caches the current bitstream position and next available
+;// bits in registers pBitStream, RBitBuffer, RBitCount. These registers
+;// are reserved for use by the bitstream decode package until you
+;// call M_BD_FINI.
+;//
+;// Next call the following macro(s) as many times as you need:
+;//
+;//    M_BD_LOOK8       - Look ahead constant 1<=N<=8  bits into the bitstream
+;//    M_BD_LOOK16      - Look ahead constant 1<=N<=16 bits into the bitstream
+;//    M_BD_READ8       - Read constant 1<=N<=8  bits from the bitstream
+;//    M_BD_READ16      - Read constant 1<=N<=16 bits from the bitstream
+;//    M_BD_VREAD8      - Read variable 1<=N<=8  bits from the bitstream
+;//    M_BD_VREAD16     - Read variable 1<=N<=16 bits from the bitstream
+;//    M_BD_VLD         - Perform variable length decode using lookup table
+;//
+;// Finally call the macro:
+;//
+;//    M_BD_FINI ppBitStream, pBitOffset
+;//
+;// This writes the bitstream state back to memory.
+;//
+;// The three bitstream cache register names are assigned to the following global
+;// variables:
+;//
+
+        GBLS    pBitStream  ;// Register name for pBitStream
+        GBLS    BitBuffer   ;// Register name for BitBuffer
+        GBLS    BitCount    ;// Register name for BitCount
+   
+;//        
+;// These register variables must have a certain defined state on entry to every bitstream
+;// macro (except M_BD_INIT) and on exit from every bitstream macro (except M_BD_FINI).
+;// The state may depend on implementation.
+;//
+;// For the default (ARM11) implementation the following hold:
+;//    pBitStream - points to the first byte not held in the BitBuffer
+;//    BitBuffer  - is a cache of (4 bytes) 32 bits, bit 31 the first bit
+;//    BitCount   - is offset (from the top bit) to the next unused bitstream bit
+;//    0<=BitCount<=15 (so BitBuffer holds at least 17 unused bits)
+;//
+;//
+
+        ;// Bitstream Decode initialise
+        ;//
+        ;// Initialises the bitstream decode global registers from
+        ;// bitstream pointers. This macro is split into 3 parts to enable
+        ;// scheduling.

+;// 
+;// ALGORITHM DESCRIPTION
+;//
+;// The 8x8 2D IDCT is performed by calculating a 1D IDCT for each
+;// column and then a 1D IDCT for each row.
+;//
+;// The 8-point 1D IDCT is defined by
+;//   f(x) = (C(0)*T(0)*c(0,x) + ... + C(7)*T(7)*c(7,x))/2
+;//
+;//   C(u) = 1/sqrt(2) if u=0 or 1 if u!=0
+;//   c(u,x) = cos( (2x+1)*u*pi/16 )
+;//
+;// We compute the 8-point 1D IDCT using the reverse of
+;// the Arai-Agui-Nakajima flow graph which we split into
+;// 5 stages named in reverse order to identify with the
+;// forward DCT. Direct inversion of the forward formulae
+;// in file FDCT_s.s gives:
+;//
+;// IStage 5:   j(u) = T(u)*A(u)  [ A(u)=4*C(u)*c(u,0) ]
+;//             [ A(0) = 2*sqrt(2)
+;//               A(u) = 4*cos(u*pi/16)  for (u!=0) ]
+;//

+;// Note:
+;// 1. The scaling by A(u)/8 can often be combined with inverse
+;//    quantization. The column and row scalings can be combined.
+;// 2. The flowgraph in the AAN paper has h4,g6 negated compared
+;//    to the above code but is otherwise identical.
+;// 3. The rotation by -pi/8 can be peformed using three multiplies
+;//    Eg  c*i4+s*i6 = (i6-i4)*s + (c+s)*i4
+;//       -s*i4+c*i6 = (i6-i4)*s + (c-s)*i6
+;// 4. If |T(u)|<=1 then from the IDCT definition,
+;//    |f(x)| <= ((1/sqrt2) + |c(1,x)| + .. + |c(7,x)|)/2
+;//            = ((1/sqrt2) + cos(pi/16) + ... + cos(7*pi/16))/2
+;//            = ((1/sqrt2) + (cot(pi/32)-1)/2)/2
+;//            = (1 + cos(pi/16) + cos(2pi/16) + cos(3pi/16))/sqrt(2)
+;//            = (approx)2.64
+;//    So the max gain of the 2D IDCT is ~x7.0 = 3 bits.

+ * 
+ * 
+ *
+ * This file allows a version of the OMX DL libraries to be built where some or
+ * all of the function names can be given a user specified suffix. 
+ *
+ * You might want to use it where:
+ *
+ * - you want to rename a function "out of the way" so that you could replace
+ *   a function with a different version (the original version would still be
+ *   in the library just with a different name - so you could debug the new
+ *   version by comparing it to the output of the old)
+ *
+ * - you want to rename all the functions to versions with a suffix so that 
+ *   you can include two versions of the library and choose between functions
+ *   at runtime.
+ *
+ *     e.g. omxIPBM_Copy_U8_C1R could be renamed omxIPBM_Copy_U8_C1R_CortexA8

+ * locations (expansion region) between the source frame edge and the plane 
+ * buffer edge.  The width/height of the expansion regions on the 
+ * horizontal/vertical edges is controlled by the parameter iExpandPels. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcDstPlane - pointer to the top-left corner of the frame to be 
+ *            expanded; must be aligned on an 8-byte boundary. 
+ *   iFrameWidth - frame width; must be a multiple of 8.

+ *            therefore the AC and DC coefficients are invalid.  Pointer must 
+ *            be aligned on an 8-byte boundary.

+ *   pSumErr - pointer to a flag indicating whether or not AC prediction is 
+ *            required; AC prediction is enabled if *pSumErr >=0, but the 
+ *            value is not used for coefficient prediction, i.e., the sum of

+; * Function: omxVCM4P2_DecodePadMV_PVOP
+; *
+; * Description:
+; * Decodes and pads four motion vectors of the non-intra macroblock in P-VOP.
+; * The motion vector padding process is specified in subclause 7.6.1.6 of
+; * ISO/IEC 14496-2.
+; *
+; * Remarks:
+; *
+; *
+; * Parameters:
+; * [in]    ppBitStream        pointer to the pointer to the current byte in
+; *                            the bit stream buffer
+; * [in]    pBitOffset         pointer to the bit position in the byte pointed
+; *                            to by *ppBitStream. *pBitOffset is valid within
+; *                            [0-7].
+; * [in]    pSrcMVLeftMB       pointers to the motion vector buffers of the
+; *                           macroblocks specially at the left side of the current macroblock
+; *                     respectively.
+; * [in]    pSrcMVUpperMB      pointers to the motion vector buffers of the
+; *                     macroblocks specially at the upper side of the current macroblock
+; *                     respectively.
+; * [in]    pSrcMVUpperRightMB pointers to the motion vector buffers of the
+; *                     macroblocks specially at the upper-right side of the current macroblock
+; *                     respectively.
+; * [in]    fcodeForward       a code equal to vop_fcode_forward in MPEG-4
+; *                     bit stream syntax
+; * [in]    MBType         the type of the current macroblock. If MBType
+; *                     is not equal to OMX_VC_INTER4V, the destination
+; *                     motion vector buffer is still filled with the
+; *                     same decoded vector.
+; * [out]   ppBitStream         *ppBitStream is updated after the block is decoded,
+; *                     so that it points to the current byte in the bit
+; *                     stream buffer
+; * [out]   pBitOffset         *pBitOffset is updated so that it points to the
+; *                     current bit position in the byte pointed by
+; *                     *ppBitStream
+; * [out]   pDstMVCurMB         pointer to the motion vector buffer of the current
+; *                     macroblock which contains four decoded motion vectors
+; *
+; * Return Value:
+; * OMX_Sts_NoErr -no error
+; * 
+; *                     
+; * OMX_Sts_Err - status error

+; * Date:       Wednesday, April 9, 2008
+; * 
+; * (c) Copyright 2007-2008 ARM Limited. All Rights Reserved.
+; * 
+; * 
+; *
+; * Description: 
+; * Contains modules for zigzag scanning and VLC decoding
+; * for inter block.
+; *
+; *
+; *
+; * Function: omxVCM4P2_DecodeVLCZigzag_Inter
+; *
+; * Description:
+; * Performs VLC decoding and inverse zigzag scan for one intra coded block.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in]    ppBitStream        pointer to the pointer to the current byte in
+; *                    the bitstream buffer
+; * [in]    pBitOffset        pointer to the bit position in the byte pointed
+; *                    to by *ppBitStream. *pBitOffset is valid within    [0-7].
+; * [in] shortVideoHeader     binary flag indicating presence of short_video_header;
+; *                           escape modes 0-3 are used if shortVideoHeader==0,
+; *                           and escape mode 4 is used when shortVideoHeader==1.
+; * [out]    ppBitStream        *ppBitStream is updated after the block is
+; *                    decoded, so that it points to the current byte
+; *                    in the bit stream buffer
+; * [out]    pBitOffset        *pBitOffset is updated so that it points to the
+; *                    current bit position in the byte pointed by
+; *                    *ppBitStream
+; * [out]    pDst            pointer to the coefficient buffer of current
+; *                    block. Must be 16-byte aligned
+; *
+; * Return Value:
+; * OMX_Sts_BadArgErr - bad arguments
+; *   -At least one of the following pointers is NULL: ppBitStream, *ppBitStream, pBitOffset, pDst, or
+; *   -pDst is not 16-byte aligned, or
+; *   -*pBitOffset exceeds [0,7].
+; * OMX_Sts_Err - status error
+; *   -At least one mark bit is equal to zero
+; *   -Encountered an illegal stream code that cannot be found in the VLC table
+; *   -Encountered and illegal code in the VLC FLC table
+; *   -The number of coefficients is greater than 64

+; * OpenMAX DL: v1.0.2
+; * Revision:   12290
+; * Date:       Wednesday, April 9, 2008
+; * 
+; * (c) Copyright 2007-2008 ARM Limited. All Rights Reserved.
+; * 
+; * 
+; * 
+; * Description:
+; * Contains module for DC/AC coefficient prediction
+; *
+; * 
+; * Function: omxVCM4P2_PredictReconCoefIntra
+; *
+; * Description:
+; * Performs adaptive DC/AC coefficient prediction for an intra block. Prior
+; * to the function call, prediction direction (predDir) should be selected
+; * as specified in subclause 7.4.3.1 of ISO/IEC 14496-2.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in]  pSrcDst      pointer to the coefficient buffer which contains the 
+; *                    quantized coefficient residuals (PQF) of the current 
+; *                    block; must be aligned on a 4-byte boundary. The 
+; *                    output coefficients are saturated to the range 
+; *                    [-2048, 2047].
+; * [in]  pPredBufRow  pointer to the coefficient row buffer; must be aligned
+; *                    on a 4-byte boundary.
+; * [in]  pPredBufCol  pointer to the coefficient column buffer; must be 
+; *                    aligned on a 4-byte boundary.
+; * [in]  curQP        quantization parameter of the current block. curQP may 
+; *                    equal to predQP especially when the current block and 
+; *                    the predictor block are in the same macroblock.
+; * [in]  predQP       quantization parameter of the predictor block
+; * [in]  predDir      indicates the prediction direction which takes one
+; *                    of the following values:
+; *                    OMX_VIDEO_HORIZONTAL    predict horizontally
+; *                    OMX_VIDEO_VERTICAL        predict vertically
+; * [in]  ACPredFlag   a flag indicating if AC prediction should be
+; *                    performed. It is equal to ac_pred_flag in the bit
+; *                    stream syntax of MPEG-4
+; * [in]  videoComp    video component type (luminance, chrominance or
+; *                    alpha) of the current block
+; * [out] pSrcDst      pointer to the coefficient buffer which contains
+; *                    the quantized coefficients (QF) of the current
+; *                    block
+; * [out] pPredBufRow  pointer to the updated coefficient row buffer
+; * [out] pPredBufCol  pointer to the updated coefficient column buffer
+; * Return Value:
+; * OMX_Sts_NoErr - no error
+; * OMX_Sts_BadArgErr - Bad arguments 
+; * - At least one of the pointers is NULL: pSrcDst, pPredBufRow, or pPredBufCol.
+; * - At least one the following cases: curQP <= 0, predQP <= 0, curQP >31, 
+; *   predQP > 31, preDir exceeds [1,2].
+; * - At least one of the pointers pSrcDst, pPredBufRow, or pPredBufCol is not 
+; *   4-byte aligned.

+; * 
+; * File Name:  omxVCM4P2_QuantInvInter_I_s.s
+; * OpenMAX DL: v1.0.2
+; * Revision:   12290
+; * Date:       Wednesday, April 9, 2008
+; * 
+; * (c) Copyright 2007-2008 ARM Limited. All Rights Reserved.
+; * 
+; * 
+; *
+; * Description: 
+; * Contains modules for inter reconstruction
+; * 
+; *
+; *
+; *
+; *
+; * Function: omxVCM4P2_QuantInvInter_I
+; *
+; * Description:
+; * Performs inverse quantization on intra/inter coded block.
+; * This function supports bits_per_pixel = 8. Mismatch control
+; * is performed for the first MPEG-4 mode inverse quantization method.
+; * The output coefficients are clipped to the range: [-2048, 2047].
+; * Mismatch control is performed for the first inverse quantization method.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in] pSrcDst          pointer to the input (quantized) intra/inter block. Must be 16-byte aligned.
+; * [in] QP              quantization parameter (quantiser_scale)
+; * [in] videoComp      (Intra version only.) Video component type of the
+; *                  current block. Takes one of the following flags:
+; *                  OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE,
+; *                  OMX_VC_ALPHA.
+; * [in] shortVideoHeader a flag indicating presence of short_video_header;
+; *                       shortVideoHeader==1 selects linear intra DC mode,
+; *                  and shortVideoHeader==0 selects nonlinear intra DC mode.
+; * [out]    pSrcDst      pointer to the output (dequantized) intra/inter block.  Must be 16-byte aligned.
+; *
+; * Return Value:
+; * OMX_Sts_NoErr - no error
+; * OMX_Sts_BadArgErr - bad arguments
+; *    - If pSrcDst is NULL or is not 16-byte aligned.
+; *      or
+; *    - If QP <= 0.
+; *      or
+; *    - videoComp is none of OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE and OMX_VC_ALPHA.

+; *
+; * 
+; * Function: omxVCM4P2_QuantInvIntra_I
+; *
+; * Description:
+; * Performs inverse quantization on intra/inter coded block.
+; * This function supports bits_per_pixel = 8. Mismatch control
+; * is performed for the first MPEG-4 mode inverse quantization method.
+; * The output coefficients are clipped to the range: [-2048, 2047].
+; * Mismatch control is performed for the first inverse quantization method.
+; *
+; * Remarks:
+; *
+; * Parameters:
+; * [in]    pSrcDst        pointer to the input (quantized) intra/inter block. Must be 16-byte aligned.
+; * [in]    QP            quantization parameter (quantiser_scale)
+; * [in]    videoComp          (Intra version only.) Video component type of the
+; *                    current block. Takes one of the following flags:
+; *                    OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE,
+; *                    OMX_VC_ALPHA.
+; * [in]    shortVideoHeader  a flag indicating presence of short_video_header;
+; *                           shortVideoHeader==1 selects linear intra DC mode,
+; *                    and shortVideoHeader==0 selects nonlinear intra DC mode.
+; * [out]    pSrcDst        pointer to the output (dequantized) intra/inter block.  Must be 16-byte aligned.
+; *
+; * Return Value:
+; * OMX_Sts_NoErr - no error
+; * OMX_Sts_BadArgErr - bad arguments
+; *    -    If pSrcDst is NULL or is not 16-byte aligned.
+; *      or
+; *    - If QP <= 0.
+; *      or
+; *    - videoComp is none of OMX_VC_LUMINANCE, OMX_VC_CHROMINANCE and OMX_VC_ALPHA.

+This transaction contains deliverables which are designated as being of
+beta release status (BET).
+
+Beta release status has a particular meaning to ARM of which the recipient
+must be aware. Beta is a pre-release status indicating that the deliverable
+so described is believed to robustly demonstrate specified behaviour, to be
+consistent across its included aspects and be ready for general deployment.
+But Beta also indicates that pre-release reliability trials are ongoing and
+that it is possible residual defects or errors in operation, consistency
+and documentation may still be encountered. The recipient should consider
+this position when using this Beta material supplied. ARM will normally
+attempt to provide fixes or a work-around for defects identified by the
+recipient, but the provision or timeliness of this support cannot be
+guaranteed. ARM shall not be responsible for direct or consequential
+damages as a result of encountering one or more of these residual defects.
+By accepting a Beta release, the recipient agrees to these constraints and
+to providing reasonable information to ARM to enable the replication of the
+defects identified by the recipient. The specific Beta version supplied
+will not be supported after release of a later or higher status version.
+It should be noted that Support for the Beta release of the deliverable
+will only be provided by ARM to a recipient who has a current support and
+maintenance contract for the deliverable.

+ * You might want to use it where:
+ *
+ * - you want to rename a function "out of the way" so that you could replace
+ *   a function with a different version (the original version would still be
+ *   in the library just with a different name - so you could debug the new
+ *   version by comparing it to the output of the old)
+ *
+ * - you want to rename all the functions to versions with a suffix so that 
+ *   you can include two versions of the library and choose between functions
+ *   at runtime.
+ *
+ *     e.g. omxIPBM_Copy_U8_C1R could be renamed omxIPBM_Copy_U8_C1R_CortexA8

+ * Input Arguments:
+ *   
+ *   pSrc - pointer to the pixels of current intra block; must be aligned on 
+ *            an 8-byte boundary. 
+ *   pPredBufRow - pointer to the coefficient row buffer containing 
+ *            ((num_mb_per_row * 2 + 1) * 8) elements of type OMX_S16. 
+ *            Coefficients are organized into blocks of eight as described 
+ *            below (Internal Prediction Coefficient Update Procedures).  The 
+ *            DC coefficient is first, and the remaining buffer locations 
+ *            contain the quantized AC coefficients. Each group of eight row 
+ *            buffer elements combined with one element eight elements ahead 
+ *            contains the coefficient predictors of the neighboring block 
+ *            that is spatially above or to the left of the block currently to 
+ *            be decoded. A negative-valued DC coefficient indicates that this 
+ *            neighboring block is not INTRA-coded or out of bounds, and 
+ *            therefore the AC and DC coefficients are invalid.  Pointer must 
+ *            be aligned on an 8-byte boundary. 
+ *   pPredBufCol - pointer to the prediction coefficient column buffer 
+ *            containing 16 elements of type OMX_S16. Coefficients are 
+ *            organized as described in section 6.2.2.5.  Pointer must be 
+ *            aligned on an 8-byte boundary. 
+ *   pSumErr - pointer to a flag indicating whether or not AC prediction is 
+ *            required; AC prediction is enabled if *pSumErr >=0, but the 
+ *            value is not used for coefficient prediction, i.e., the sum of 
+ *            absolute differences starts from 0 for each call to this 
+ *            function.  Otherwise AC prediction is disabled if *pSumErr < 0 . 
+ *   blockIndex - block index indicating the component type and position, as 
+ *            defined in [ISO14496-2], subclause 6.1.3.8. 
+ *   curQp - quantization parameter of the macroblock to which the current 
+ *            block belongs

+ *            block left of the current block (QPa), and pQpBuf[1] contains 
+ *            the quantization parameter associated with the 8x8 block above 
+ *            the current block (QPc).  In the event that the corresponding 
+ *            block is outside of the VOP bound, the Qp value will not affect 
+ *            the intra prediction process, as described in [ISO14496-2], 
+ *            sub-clause 7.4.3.3,  Adaptive AC Coefficient Prediction.  
+ *   srcStep - width of the source buffer; must be a multiple of 8. 
+ *   dstStep - width of the reconstructed destination buffer; must be a 
+ *            multiple of 16. 
+ *   shortVideoHeader - binary flag indicating presence of 
+ *            short_video_header; shortVideoHeader==1 selects linear intra DC 
+ *            mode, and shortVideoHeader==0 selects non linear intra DC mode. 
+ *
+ * Output Arguments:
+ *   
+ *   pDst - pointer to the quantized DCT coefficient buffer; pDst[0] contains 
+ *            the predicted DC coefficient; the remaining entries contain the 
+ *            quantized AC coefficients (without prediction).  The pointer 
+ *            pDstmust be aligned on a 16-byte boundary. 
+ *   pRec - pointer to the reconstructed texture; must be aligned on an 
+ *            8-byte boundary. 
+ *   pPredBufRow - pointer to the updated coefficient row buffer

+ *            VLC encoding. The entry pPreACPredict[0]indicates prediction 
+ *            direction for the current block and takes one of the following 
+ *            values: OMX_VC_NONE (prediction disabled), OMX_VC_HORIZONTAL, or

+ *            pPreACPredict[1]-pPreACPredict[7]contain predicted AC 
+ *            coefficients.  If prediction is disabled (*pSumErr<0) then the 
+ *            contents of this buffer are undefined upon return from the

+ * Function:  omxVCM4P2_MCReconBlock   (6.2.5.5.1)
+ *
+ * Description:
+ * Performs motion compensation prediction for an 8x8 block using 
+ * interpolation described in [ISO14496-2], subclause 7.6.2. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrc - pointer to the block in the reference plane. 
+ *   srcStep - distance between the start of consecutive lines in the 
+ *            reference plane, in bytes; must be a multiple of 8. 
+ *   dstStep - distance between the start of consecutive lines in the 
+ *            destination plane, in bytes; must be a multiple of 8. 
+ *   pSrcResidue - pointer to a buffer containing the 16-bit prediction 
+ *            residuals; must be 16-byte aligned. If the pointer is NULL, then 
+ *            no prediction is done, only motion compensation, i.e., the block 
+ *            is moved with interpolation. 
+ *   predictType - bilinear interpolation type, as defined in section 
+ *            6.2.1.2. 
+ *   rndVal - rounding control parameter: 0 - disabled; 1 - enabled. 
+ *
+ * Output Arguments:
+ *   
+ *   pDst - pointer to the destination buffer; must be 8-byte aligned.  If 
+ *            prediction residuals are added then output intensities are 
+ *            clipped to the range [0,255]. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments; returned under any of the following 
+ *              conditions: 
+ *    -    pDst is not 8-byte aligned. 
+ *    -    pSrcResidue is not 16-byte aligned. 
+ *    -    one or more of the following pointers is NULL: pSrc or pDst. 
+ *    -    either srcStep or dstStep is not a multiple of 8. 
+ *    -    invalid type specified for the parameter predictType. 
+ *    -    the parameter rndVal is not equal either to 0 or 1.

+ * Description:
+ * This function expands a reconstructed frame in-place.  The unexpanded 
+ * source frame should be stored in a plane buffer with sufficient space 
+ * pre-allocated for edge expansion, and the input frame should be located in 
+ * the plane buffer center.  This function executes the pixel expansion by 
+ * replicating source frame edge pixel intensities in the empty pixel 
+ * locations (expansion region) between the source frame edge and the plane 
+ * buffer edge.  The width/height of the expansion regions on the 
+ * horizontal/vertical edges is controlled by the parameter iExpandPels. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcDstPlane - pointer to the top-left corner of the frame to be 
+ *            expanded; must be aligned on an 8-byte boundary. 
+ *   iFrameWidth - frame width; must be a multiple of 8. 
+ *   iFrameHeight -frame height; must be a multiple of 8. 
+ *   iExpandPels - number of pixels to be expanded in the horizontal and 
+ *            vertical directions; must be a multiple of 8. 
+ *   iPlaneStep - distance, in bytes, between the start of consecutive lines 
+ *            in the plane buffer; must be larger than or equal to 
+ *            (iFrameWidth + 2 * iExpandPels). 
+ *
+ * Output Arguments:
+ *   
+ *   pSrcDstPlane -Pointer to the top-left corner of the frame (NOT the 
+ *            top-left corner of the plane); must be aligned on an 8-byte 
+ *            boundary.

+ * Function:  omxVCM4P10_BlockMatch_Quarter   (6.3.5.2.3)
+ *
+ * Description:
+ * Performs a quarter-pel block match using results from a prior half-pel 
+ * search.  Returns the best MV and associated cost.  This function estimates 
+ * the quarter-pixel motion vector by interpolating the half-pel resolution 
+ * motion vector referenced by the input parameter pSrcDstBestMV, i.e., the 
+ * initial half-pel MV is generated externally.  The function 
+ * omxVCM4P10_BlockMatch_Half may be used for half-pel motion estimation. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcOrgY - Pointer to the current position in original picture plane. If 
+ *            iBlockWidth==4,  4-byte alignment required. If iBlockWidth==8,  
+ *            8-byte alignment required. If iBlockWidth==16, 16-byte alignment 
+ *            required. 
+ *   pSrcRefY - Pointer to the top-left corner of the co-located block in the 
+ *            reference picture  If iBlockWidth==4,  4-byte alignment 
+ *            required.  If iBlockWidth==8,  8-byte alignment required.  If 
+ *            iBlockWidth==16, 16-byte alignment required. 
+ *   nSrcOrgStep - Stride of the original picture plane in terms of full 
+ *            pixels; must be a multiple of iBlockWidth. 
+ *   nSrcRefStep - Stride of the reference picture plane in terms of full 
+ *            pixels 
+ *   iBlockWidth - Width of the current block in terms of full pixels; must 
+ *            be equal to either 4, 8, or 16. 
+ *   iBlockHeight - Height of the current block in terms of full pixels; must 
+ *            be equal to either 4, 8, or 16. 
+ *   nLamda - Lamda factor, used to compute motion cost 
+ *   pMVPred - Predicted MV, represented in terms of 1/4-pel units; used to 
+ *            compute motion cost 
+ *   pSrcDstBestMV - The best MV resulting from a prior half-pel search, 
+ *            represented in terms of 1/4 pel units 
+ *
+ * Output Arguments:
+ *   
+ *   pSrcDstBestMV - Best MV resulting from the quarter-pel search, expressed 
+ *            in terms of 1/4-pel units 
+ *   pBestCost - Motion cost associated with the best MV; computed as 
+ *            SAD+Lamda*BitsUsedByMV 
+ *
+ * Return Value:
+ *    OMX_Sts_NoErr, if the function runs without error.
+ *    OMX_Sts_BadArgErr - bad arguments: if one of the following cases occurs: 
+ *    -    One of more of the following pointers is NULL: 
+ *         pSrcOrgY, pSrcRefY, pSrcDstBestMV, pMVPred, pBestCost 
+ *    -    iBlockWidth or iBlockHeight are equal to values other than 4, 8, or 16. 
+ *    -    Any alignment restrictions are violated

+ * Input Arguments:

+ *   pOffset - Pointer to current bit position in the byte pointed to by

+ *
+ * Output Arguments:

+ *            the caller is expected to bypass the transform/dequantization of 
+ *            the empty blocks. 
+ *
+ * Return Value:

+ * Function:  omxVCM4P10_FilterDeblockingLuma_VerEdge_I   (6.3.3.3.1)
+ *
+ * Description:
+ * Performs in-place deblock filtering on four vertical edges of the luma 
+ * macroblock (16x16). 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcDst - Pointer to the input macroblock; must be 16-byte aligned. 
+ *   srcdstStep -Step of the arrays; must be a multiple of 16. 
+ *   pAlpha -Array of size 2 of alpha thresholds (the first item is the alpha 
+ *            threshold for the external vertical edge, and the second item is 
+ *            for the internal vertical edge); per [ISO14496-10] alpha values 
+ *            must be in the range [0,255]. 
+ *   pBeta -Array of size 2 of beta thresholds (the first item is the beta 
+ *            threshold for the external vertical edge, and the second item is 
+ *            for the internal vertical edge); per [ISO14496-10] beta values 
+ *            must be in the range [0,18]. 
+ *   pThresholds -Array of size 16 of Thresholds (TC0) (values for the left 
+ *            edge of each 4x4 block, arranged in vertical block order); must 
+ *            be aligned on a 4-byte boundary..  Per [ISO14496-10] values must 
+ *            be in the range [0,25]. 
+ *   pBS -Array of size 16 of BS parameters (arranged in vertical block 
+ *            order); valid in the range [0,4] with the following 
+ *            restrictions: i) pBS[i]== 4 may occur only for 0<=i<=3, ii) 
+ *            pBS[i]== 4 if and only if pBS[i^3]== 4.  Must be 4-byte aligned. 
+ *
+ * Output Arguments:
+ *   
+ *   pSrcDst -Pointer to filtered output macroblock. 
+ *
+ * Return Value:
+ *    If the function runs without error, it returns OMX_Sts_NoErr. 
+ *    If one of the following cases occurs, the function returns 
+ *              OMX_Sts_BadArgErr: 
+ *    Either of the pointers in pSrcDst, pAlpha, pBeta, pThresholds, or pBS 
+ *              is NULL. 
+ *    Either pThresholds or pBS is not aligned on a 4-byte boundary. 
+ *    pSrcDst is not 16-byte aligned. 
+ *    srcdstStep is not a multiple of 16. 
+ *    pAlpha[0] and/or pAlpha[1] is outside the range [0,255]. 
+ *    pBeta[0] and/or pBeta[1] is outside the range [0,18]. 
+ *    One or more entries in the table pThresholds[0..15]is outside of the 
+ *              range [0,25]. 
+ *    pBS is out of range, i.e., one of the following conditions is true: 
+ *              pBS[i]<0, pBS[i]>4, pBS[i]==4 for i>=4, or (pBS[i]==4 &&

+ *
+ * Description:
+ * Performs MB-level motion estimation and selects best motion estimation 
+ * strategy from the set of modes supported in baseline profile [ISO14496-10]. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcCurrBuf - Pointer to the current position in original picture plane; 
+ *            16-byte alignment required 
+ *   pSrcRefBufList - Pointer to an array with 16 entries.  Each entry points 
+ *            to the top-left corner of the co-located MB in a reference 
+ *            picture.  The array is filled from low-to-high with valid 
+ *            reference frame pointers; the unused high entries should be set 
+ *            to NULL.  Ordering of the reference frames should follow 
+ *            [ISO14496-10] subclause 8.2.4  Decoding Process for Reference 
+ *            Picture Lists.   The entries must be 16-byte aligned. 
+ *   pSrcRecBuf - Pointer to the top-left corner of the co-located MB in the 
+ *            reconstructed picture; must be 16-byte aligned. 
+ *   SrcCurrStep - Width of the original picture plane in terms of full 
+ *            pixels; must be a multiple of 16. 
+ *   SrcRefStep - Width of the reference picture plane in terms of full 
+ *            pixels; must be a multiple of 16. 
+ *   SrcRecStep - Width of the reconstructed picture plane in terms of full 
+ *            pixels; must be a multiple of 16. 
+ *   pRefRect - Pointer to the valid reference rectangle; relative to the 
+ *            image origin. 
+ *   pCurrPointPos - Position of the current macroblock in the current plane. 
+ *   Lambda - Lagrange factor for computing the cost function 
+ *   pMESpec - Pointer to the motion estimation specification structure; must 
+ *            have been allocated and initialized prior to calling this 
+ *            function. 
+ *   pMBInter - Array, of dimension four, containing pointers to information 
+ *            associated with four adjacent type INTER MBs (Left, Top, 
+ *            Top-Left, Top-Right). Any pointer in the array may be set equal 
+ *            to NULL if the corresponding MB doesn t exist or is not of type 
+ *            INTER. pMBInter[0] - Pointer to left MB information pMBInter[1] 
+ *            - Pointer to top MB information pMBInter[2] - Pointer to 
+ *            top-left MB information pMBInter[3] - Pointer to top-right MB 
+ *            information 
+ *   pMBIntra - Array, of dimension four, containing pointers to information 
+ *            associated with four adjacent type INTRA MBs (Left, Top, 
+ *            Top-Left, Top-Right). Any pointer in the array may be set equal 
+ *            to NULL if the corresponding MB doesn t exist or is not of type 
+ *            INTRA. pMBIntra[0] - Pointer to left MB information pMBIntra[1] 
+ *            - Pointer to top MB information pMBIntra[2] - Pointer to 
+ *            top-left MB information pMBIntra[3] - Pointer to top-right MB 
+ *            information 
+ *   pSrcDstMBCurr - Pointer to information structure for the current MB.  
+ *            The following entries should be set prior to calling the 
+ *            function:  sliceID - the number of the slice the to which the 
+ *            current MB belongs. 
+ *
+ * Output Arguments:
+ *   
+ *   pDstCost - Pointer to the minimum motion cost for the current MB. 
+ *   pDstBlockSAD - Pointer to the array of SADs for each of the sixteen luma 
+ *            4x4 blocks in each MB.  The block SADs are in scan order for 
+ *            each MB.  For implementations that cannot compute the SAD values 
+ *            individually, the maximum possible value (0xffff) is returned 
+ *            for each of the 16 block SAD entries. 
+ *   pSrcDstMBCurr - Pointer to updated information structure for the current 
+ *            MB after MB-level motion estimation has been completed.  The 
+ *            following fields are updated by the ME function.   The following 
+ *            parameter set quantifies the MB-level ME search results: MbType 
+ *            subMBType[4] pMV0[4][4] pMVPred[4][4] pRefL0Idx[4] 
+ *            Intra16x16PredMode pIntra4x4PredMode[4][4] 
+ *
+ * Return Value:
+ *    OMX_Sts_NoErr, if the function runs without error.
+ *    OMX_Sts_BadArgErr - bad arguments: if one of the following cases occurs: 
+ *    -   One of more of the following pointers is NULL: pSrcCurrBuf, 
+ *           pSrcRefBufList, pSrcRecBuf, pRefRect, pCurrPointPos, pMESpec,

+/**
+ * Function:  omxVCM4P10_PredictIntraChroma_8x8   (6.3.3.1.3)
+ *
+ * Description:
+ * Performs intra prediction for chroma samples. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcLeft - Pointer to the buffer of 8 left pixels: p[x, y] (x = -1, y= 
+ *            0..7). 
+ *   pSrcAbove - Pointer to the buffer of 8 above pixels: p[x,y] (x = 0..7, y 
+ *            = -1); must be aligned on an 8-byte boundary. 
+ *   pSrcAboveLeft - Pointer to the above left pixels: p[x,y] (x = -1, y = -1) 
+ *   leftStep - Step of left pixel buffer; must be a multiple of 8. 
+ *   dstStep - Step of the destination buffer; must be a multiple of 8. 
+ *   predMode - Intra chroma prediction mode, please refer to section 3.4.3. 
+ *   availability - Neighboring chroma block availability flag, please refer 
+ *            to  "Neighboring Macroblock Availability". 
+ *
+ * Output Arguments:
+ *   
+ *   pDst - Pointer to the destination buffer; must be aligned on an 8-byte 
+ *            boundary. 
+ *
+ * Return Value:
+ *    If the function runs without error, it returns OMX_Sts_NoErr. 
+ *    If any of the following cases occurs, the function returns 
+ *              OMX_Sts_BadArgErr: 
+ *    pDst is NULL. 
+ *    dstStep < 8 or dstStep is not a multiple of 8. 
+ *    leftStep is not a multiple of 8. 
+ *    predMode is not in the valid range of enumeration 
+ *              OMXVCM4P10IntraChromaPredMode. 
+ *    predMode is OMX_VC_CHROMA_VERT, but availability doesn't set 
+ *              OMX_VC_UPPER indicating p[x,-1] (x = 0..7) is not available. 
+ *    predMode is OMX_VC_CHROMA_HOR, but availability doesn't set OMX_VC_LEFT 
+ *              indicating p[-1,y] (y = 0..7) is not available. 
+ *    predMode is OMX_VC_CHROMA_PLANE, but availability doesn't set 
+ *              OMX_VC_UPPER_LEFT or OMX_VC_UPPER or OMX_VC_LEFT indicating 
+ *              p[x,-1](x = 0..7), or p[-1,y] (y = 0..7), or p[-1,-1] is not 
+ *              available. 
+ *    availability sets OMX_VC_UPPER, but pSrcAbove is NULL. 
+ *    availability sets OMX_VC_LEFT, but pSrcLeft is NULL. 
+ *    availability sets OMX_VC_UPPER_LEFT, but pSrcAboveLeft is NULL. 
+ *    either pSrcAbove or pDst is not aligned on a 8-byte boundary.  Note: 
+ *              pSrcAbove, pSrcAbove, pSrcAboveLeft may be invalid pointer if 
+ *              they are not used by intra prediction implied in predMode. 
+ *               Note: OMX_VC_UPPER_RIGHT is not used in intra chroma

+ *
+ * Description:
+ * Perform Intra_16x16 prediction for luma samples. If the upper-right block 
+ * is not available, then duplication work should be handled inside the 
+ * function. Users need not define them outside. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcLeft - Pointer to the buffer of 16 left pixels: p[x, y] (x = -1, y = 
+ *            0..15) 
+ *   pSrcAbove - Pointer to the buffer of 16 above pixels: p[x,y] (x = 0..15, 
+ *            y= -1); must be aligned on a 16-byte boundary. 
+ *   pSrcAboveLeft - Pointer to the above left pixels: p[x,y] (x = -1, y = -1) 
+ *   leftStep - Step of left pixel buffer; must be a multiple of 16. 
+ *   dstStep - Step of the destination buffer; must be a multiple of 16. 
+ *   predMode - Intra_16x16 prediction mode, please refer to section 3.4.1. 
+ *   availability - Neighboring 16x16 MB availability flag. Refer to 
+ *                  section 3.4.4. 
+ *
+ * Output Arguments:
+ *   
+ *   pDst -Pointer to the destination buffer; must be aligned on a 16-byte 
+ *            boundary. 
+ *
+ * Return Value:
+ *    If the function runs without error, it returns OMX_Sts_NoErr. 
+ *    If one of the following cases occurs, the function returns 
+ *              OMX_Sts_BadArgErr: 
+ *    pDst is NULL. 
+ *    dstStep < 16. or dstStep is not a multiple of 16. 
+ *    leftStep is not a multiple of 16. 
+ *    predMode is not in the valid range of enumeration 
+ *              OMXVCM4P10Intra16x16PredMode 
+ *    predMode is OMX_VC_16X16_VERT, but availability doesn't set 
+ *              OMX_VC_UPPER indicating p[x,-1] (x = 0..15) is not available. 
+ *    predMode is OMX_VC_16X16_HOR, but availability doesn't set OMX_VC_LEFT 
+ *              indicating p[-1,y] (y = 0..15) is not available. 
+ *    predMode is OMX_VC_16X16_PLANE, but availability doesn't set 
+ *              OMX_VC_UPPER_LEFT or OMX_VC_UPPER or OMX_VC_LEFT indicating 
+ *              p[x,-1](x = 0..15), or p[-1,y] (y = 0..15), or p[-1,-1] is not 
+ *              available. 
+ *    availability sets OMX_VC_UPPER, but pSrcAbove is NULL. 
+ *    availability sets OMX_VC_LEFT, but pSrcLeft is NULL. 
+ *    availability sets OMX_VC_UPPER_LEFT, but pSrcAboveLeft is NULL. 
+ *    either pSrcAbove or pDst is not aligned on a 16-byte boundary.  
+ *
+ * Note: 
+ *     pSrcAbove, pSrcAbove, pSrcAboveLeft may be invalid pointers if 
+ *     they are not used by intra prediction implied in predMode. 
+ * Note: 
+ *     OMX_VC_UPPER_RIGHT is not used in intra_16x16 luma prediction.

+ * pDstQuantCoeff. This function can also output dequantized coefficients or 
+ * unquantized DC coefficients optionally by setting the pointers 
+ * pDstDeQuantCoeff, pDCCoeff. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcOrg - Pointer to original signal. 4-byte alignment required. 
+ *   pSrcPred - Pointer to prediction signal. 4-byte alignment required. 
+ *   iSrcOrgStep - Step of the original signal buffer; must be a multiple of 
+ *            4. 
+ *   iSrcPredStep - Step of the prediction signal buffer; must be a multiple 
+ *            of 4. 
+ *   pNumCoeff -Number of non-zero coefficients after quantization. If this 
+ *            parameter is not required, it is set to NULL. 
+ *   nThreshSAD - Zero-block early detection threshold. If this parameter is 
+ *            not required, it is set to 0. 
+ *   iQP - Quantization parameter; must be in the range [0,51]. 
+ *   bIntra - Indicates whether this is an INTRA block, either 1-INTRA or 
+ *            0-INTER 
+ *
+ * Output Arguments:
+ *   
+ *   pDstQuantCoeff - Pointer to the quantized transformed coefficients.  
+ *            8-byte alignment required. 
+ *   pDstDeQuantCoeff - Pointer to the dequantized transformed coefficients 
+ *            if this parameter is not equal to NULL.  8-byte alignment

+ *
+ * Remarks:
+ *
+ * Parameters:
+ * [in] pSrcDst     pointer to the coefficient buffer which contains
+ *                          the quantized coefficient residuals (PQF) of the
+ *                          current block
+ * [in] pPredBufRow pointer to the coefficient row buffer
+ * [in] pPredBufCol pointer to the coefficient column buffer
+ * [in] curQP       quantization parameter of the current block. curQP
+ *                          may equal to predQP especially when the current
+ *                          block and the predictor block are in the same
+ *                          macroblock.
+ * [in] predQP      quantization parameter of the predictor block
+ * [in] predDir     indicates the prediction direction which takes one
+ *                          of the following values:
+ *                          OMX_VC_HORIZONTAL    predict horizontally
+ *                          OMX_VC_VERTICAL      predict vertically
+ * [in] ACPredFlag  a flag indicating if AC prediction should be
+ *                          performed. It is equal to ac_pred_flag in the bit
+ *                          stream syntax of MPEG-4
+ * [in] videoComp   video component type (luminance, chrominance or
+ *                          alpha) of the current block
+ * [in] flag        This flag defines the if one wants to use this functions to
+ *                  calculate PQF (set 1, prediction) or QF (set 0, reconstruction)
+ * [out]    pPreACPredict   pointer to the predicted coefficients buffer.
+ *                          Filled ONLY if it is not NULL
+ * [out]    pSrcDst     pointer to the coefficient buffer which contains
+ *                          the quantized coefficients (QF) of the current
+ *                          block
+ * [out]    pPredBufRow pointer to the updated coefficient row buffer

+ * Function: armVCM4P2_BlockMatch_Half
+ *
+ * Description:
+ * Performs a 16x16 block match with half-pixel resolution.  Returns the estimated 
+ * motion vector and associated minimum SAD.  This function estimates the half-pixel 
+ * motion vector by interpolating the integer resolution motion vector referenced 
+ * by the input parameter pSrcDstMV, i.e., the initial integer MV is generated 
+ * externally.  The input parameters pSrcRefBuf and pSearchPointRefPos should be 
+ * shifted by the winning MV of 16x16 integer search prior to calling BlockMatch_Half_16x16.  
+ * The function BlockMatch_Integer_16x16 may be used for integer motion estimation.
+ *
+ * Remarks:
+ *
+ * Parameters:
+ * [in]	pSrcRefBuf		pointer to the reference Y plane; points to the reference MB 
+ *                    that corresponds to the location of the current macroblock in 
+ *                    the	current plane.
+ * [in]	refWidth		  width of the reference plane

+ * Function: armVCM4P2_BlockMatch_Integer
+ *
+ * Description:
+ * Performs a 16x16 block search; estimates motion vector and associated minimum SAD.  
+ * Both the input and output motion vectors are represented using half-pixel units, and 
+ * therefore a shift left or right by 1 bit may be required, respectively, to match the 
+ * input or output MVs with other functions that either generate output MVs or expect 
+ * input MVs represented using integer pixel units. 
+ *
+ * Remarks:
+ *
+ * Parameters:
+ * [in]	pSrcRefBuf		pointer to the reference Y plane; points to the reference MB that 
+ *                    corresponds to the location of the current macroblock in the current 
+ *                    plane.
+ * [in]	refWidth		  width of the reference plane
+ * [in]	pRefRect		  pointer to the valid rectangular in reference plane. Relative to image origin. 
+ *                    It's not limited to the image boundary, but depended on the padding. For example, 
+ *                    if you pad 4 pixels outside the image border, then the value for left border 
+ *                    can be -4
+ * [in]	pSrcCurrBuf		pointer to the current macroblock extracted from original plane (linear array, 
+ *                    256 entries); must be aligned on an 8-byte boundary.
+ * [in] pCurrPointPos	position of the current macroblock in the current plane
+ * [in] pSrcPreMV		  pointer to predicted motion vector; NULL indicates no predicted MV
+ * [in] pSrcPreSAD		pointer to SAD associated with the predicted MV (referenced by pSrcPreMV)
+ * [in] searchRange		search range for 16X16 integer block,the units of it is full pixel,the search range 
+ *                    is the same in all directions.It is in inclusive of the boundary and specified in 
+ *                    terms of integer pixel units.
+ * [in] pMESpec			  vendor-specific motion estimation specification structure; must have been allocated 
+ *                    and then initialized using omxVCM4P2_MEInit prior to calling the block matching 
+ *                    function.
+ * [out]	pDstMV			pointer to estimated MV
+ * [out]	pDstSAD			pointer to minimum SAD
+ *
+ * Return Value:
+ * OMX_Sts_NoErr ¨C no error.
+ * OMX_Sts_BadArgErr ¨C bad arguments

+ * Checks the type of Escape Mode and put encoded bits for 
+ * quantized DCT coefficients.
+ *
+ * Remarks:
+ *
+ * Parameters:
+ * [in]	 ppBitStream      pointer to the pointer to the current byte in
+ *						  the bit stream
+ * [in]	 pBitOffset       pointer to the bit position in the byte pointed
+ *                        by *ppBitStream. Valid within 0 to 7
+ * [in] shortVideoHeader binary flag indicating presence of short_video_header; escape modes 0-3 are used if shortVideoHeader==0,
+ *                           and escape mode 4 is used when shortVideoHeader==1.
+ * [in]  start            start indicates whether the encoding begins with 
+ *                        0th element or 1st.
+ * [in]  maxStoreRunL0    Max store possible (considering last and inter/intra)
+ *                        for last = 0
+ * [in]  maxStoreRunL1    Max store possible (considering last and inter/intra)
+ *                        for last = 1

+ * [in]  pLMAXTableL1     Level MAX table defined in 
+ *                        armVCM4P2_Huff_Tables_VLC.c for last == 1
+ * [in]  pRMAXTableL0     Run MAX table defined in 
+ *                        armVCM4P2_Huff_Tables_VLC.c for last == 0
+ * [in]  pRMAXTableL1     Run MAX table defined in 
+ *                        armVCM4P2_Huff_Tables_VLC.c for last == 1
+ * [out] pQDctBlkCoef     pointer to the quantized DCT coefficient
+ * [out] ppBitStream      *ppBitStream is updated after the block is encoded
+ *                        so that it points to the current byte in the bit
+ *                        stream buffer.
+ * [out] pBitOffset       *pBitOffset is updated so that it points to the

+ *
+ * Description:
+ * Decodes and pads the four motion vectors associated with a non-intra P-VOP 
+ * macroblock.  For macroblocks of type OMX_VC_INTER4V, the output MV is 
+ * padded as specified in [ISO14496-2], subclause 7.6.1.6. Otherwise, for 
+ * macroblocks of types other than OMX_VC_INTER4V, the decoded MV is copied to 
+ * all four output MV buffer entries. 
+ *
+ * Input Arguments:
+ *   
+ *   ppBitStream - pointer to the pointer to the current byte in the bit 
+ *            stream buffer 
+ *   pBitOffset - pointer to the bit position in the byte pointed to by 
+ *            *ppBitStream. *pBitOffset is valid within [0-7]. 
+ *   pSrcMVLeftMB, pSrcMVUpperMB, and pSrcMVUpperRightMB - pointers to the 
+ *            motion vector buffers of the macroblocks specially at the left, 
+ *            upper, and upper-right side of the current macroblock, 
+ *            respectively; a value of NULL indicates unavailability.  Note: 
+ *            Any neighborhood macroblock outside the current VOP or video 
+ *            packet or outside the current GOB (when short_video_header is 
+ *             1 ) for which gob_header_empty is  0  is treated as 
+ *            transparent, according to [ISO14496-2], subclause 7.6.5. 
+ *   fcodeForward - a code equal to vop_fcode_forward in MPEG-4 bit stream 
+ *            syntax 
+ *   MBType - the type of the current macroblock. If MBType is not equal to 
+ *            OMX_VC_INTER4V, the destination motion vector buffer is still 
+ *            filled with the same decoded vector. 
+ *
+ * Output Arguments:
+ *   
+ *   ppBitStream - *ppBitStream is updated after the block is decoded, so 
+ *            that it points to the current byte in the bit stream buffer 
+ *   pBitOffset - *pBitOffset is updated so that it points to the current bit 
+ *            position in the byte pointed by *ppBitStream 
+ *   pDstMVCurMB - pointer to the motion vector buffer for the current 
+ *            macroblock; contains four decoded motion vectors 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments:
+ *    -    At least one of the following pointers is NULL: 
+ *         ppBitStream, *ppBitStream, pBitOffset, pDstMVCurMB 
+ *    -    *pBitOffset exceeds [0,7]

+ * Function:  omxVCM4P2_DecodeVLCZigzag_IntraACVLC   (6.2.5.2.2)
+ *
+ * Description:
+ * Performs VLC decoding and inverse zigzag scan of AC and DC coefficients 
+ * for one intra block.  Two versions of the function (DCVLC and ACVLC) are 
+ * provided in order to support the two different methods of processing DC 
+ * coefficients, as described in [ISO14496-2], subclause 7.4.1.4,  Intra DC 
+ * Coefficient Decoding for the Case of Switched VLC Encoding.  
+ *
+ * Input Arguments:
+ *   
+ *   ppBitStream - pointer to the pointer to the current byte in the 
+ *            bitstream buffer 
+ *   pBitOffset - pointer to the bit position in the current byte referenced 
+ *            by *ppBitStream.  The parameter *pBitOffset is valid in the 
+ *            range [0-7]. Bit Position in one byte:  |Most Least| *pBitOffset 
+ *            |0 1 2 3 4 5 6 7| 
+ *   predDir - AC prediction direction; used to select the zigzag scan 
+ *            pattern; takes one of the following values: OMX_VC_NONE - AC 
+ *            prediction not used; performs classical zigzag scan. 
+ *            OMX_VC_HORIZONTAL - Horizontal prediction; performs 
+ *            alternate-vertical zigzag scan; OMX_VC_VERTICAL - Vertical 
+ *            prediction; performs alternate-horizontal zigzag scan. 
+ *   shortVideoHeader - binary flag indicating presence of 
+ *            short_video_header; escape modes 0-3 are used if 
+ *            shortVideoHeader==0, and escape mode 4 is used when 
+ *            shortVideoHeader==1. 
+ *   videoComp - video component type (luminance or chrominance) of the 
+ *            current block 
+ *
+ * Output Arguments:
+ *   
+ *   ppBitStream - *ppBitStream is updated after the block is decoded such 
+ *            that it points to the current byte in the bit stream buffer 
+ *   pBitOffset - *pBitOffset is updated such that it points to the current 
+ *            bit position in the byte pointed by *ppBitStream 
+ *   pDst - pointer to the coefficient buffer of current block; must be 
+ *            4-byte aligned. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments At least one of the following 
+ *              pointers is NULL: ppBitStream, *ppBitStream, pBitOffset, pDst,

+ * Function:  omxVCM4P2_FindMVpred   (6.2.3.1.1)
+ *
+ * Description:
+ * Predicts a motion vector for the current block using the procedure 
+ * specified in [ISO14496-2], subclause 7.6.5.  The resulting predicted MV is 
+ * returned in pDstMVPred. If the parameter pDstMVPredME if is not NULL then 
+ * the set of three MV candidates used for prediction is also returned, 
+ * otherwise pDstMVPredMEis NULL upon return. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcMVCurMB - pointer to the MV buffer associated with the current Y 
+ *            macroblock; a value of NULL indicates unavailability. 
+ *   pSrcCandMV1 - pointer to the MV buffer containing the 4 MVs associated 
+ *            with the MB located to the left of the current MB; set to NULL 
+ *            if there is no MB to the left. 
+ *   pSrcCandMV2 - pointer to the MV buffer containing the 4 MVs associated 
+ *            with the MB located above the current MB; set to NULL if there 
+ *            is no MB located above the current MB. 
+ *   pSrcCandMV3 - pointer to the MV buffer containing the 4 MVs associated 
+ *            with the MB located to the right and above the current MB; set 
+ *            to NULL if there is no MB located to the above-right. 
+ *   iBlk - the index of block in the current macroblock 
+ *   pDstMVPredME - MV candidate return buffer;  if set to NULL then 
+ *            prediction candidate MVs are not returned and pDstMVPredME will 
+ *            be NULL upon function return; if pDstMVPredME is non-NULL then it 
+ *            must point to a buffer containing sufficient space for three 
+ *            return MVs. 
+ *
+ * Output Arguments:
+ *   
+ *   pDstMVPred - pointer to the predicted motion vector 
+ *   pDstMVPredME - if non-NULL upon input then pDstMVPredME  points upon 
+ *            return to a buffer containing the three motion vector candidates 
+ *            used for prediction as specified in [ISO14496-2], subclause 
+ *            7.6.5, otherwise if NULL upon input then pDstMVPredME is NULL 
+ *            upon output. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments; returned under any of the following 
+ *              conditions: 
+ *    -    the pointer pDstMVPred is NULL 
+ *    -    the parameter iBlk does not fall into the range 0 <= iBlk<=3

+ * Function:  omxVCM4P2_MCReconBlock   (6.2.5.5.1)
+ *
+ * Description:
+ * Performs motion compensation prediction for an 8x8 block using 
+ * interpolation described in [ISO14496-2], subclause 7.6.2. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrc - pointer to the block in the reference plane. 
+ *   srcStep - distance between the start of consecutive lines in the 
+ *            reference plane, in bytes; must be a multiple of 8. 
+ *   dstStep - distance between the start of consecutive lines in the 
+ *            destination plane, in bytes; must be a multiple of 8. 
+ *   pSrcResidue - pointer to a buffer containing the 16-bit prediction 
+ *            residuals; must be 16-byte aligned. If the pointer is NULL, then 
+ *            no prediction is done, only motion compensation, i.e., the block 
+ *            is moved with interpolation. 
+ *   predictType - bilinear interpolation type, as defined in section 
+ *            6.2.1.2. 
+ *   rndVal - rounding control parameter: 0 - disabled; 1 - enabled. 
+ *
+ * Output Arguments:
+ *   
+ *   pDst - pointer to the destination buffer; must be 8-byte aligned.  If 
+ *            prediction residuals are added then output intensities are 
+ *            clipped to the range [0,255]. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments; returned under any of the following 
+ *              conditions: 
+ *    -    pDst is not 8-byte aligned. 
+ *    -    pSrcResidue is not 16-byte aligned. 
+ *    -    one or more of the following pointers is NULL: pSrc or pDst. 
+ *    -    either srcStep or dstStep is not a multiple of 8. 
+ *    -    invalid type specified for the parameter predictType. 
+ *    -    the parameter rndVal is not equal either to 0 or 1.

+ * Function:  omxVCM4P2_MotionEstimationMB   (6.2.4.3.1)
+ *
+ * Description:
+ * Performs motion search for a 16x16 macroblock.  Selects best motion search 
+ * strategy from among inter-1MV, inter-4MV, and intra modes.  Supports 
+ * integer and half pixel resolution. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcCurrBuf - pointer to the top-left corner of the current MB in the 
+ *            original picture plane; must be aligned on a 16-byte boundary.  
+ *            The function does not expect source data outside the region 
+ *            bounded by the MB to be available; for example it is not 
+ *            necessary for the caller to guarantee the availability of 
+ *            pSrcCurrBuf[-SrcCurrStep], i.e., the row of pixels above the MB 
+ *            to be processed. 
+ *   srcCurrStep - width of the original picture plane, in terms of full 
+ *            pixels; must be a multiple of 16. 
+ *   pSrcRefBuf - pointer to the reference Y plane; points to the reference 
+ *            plane location corresponding to the location of the current 
+ *            macroblock in the current plane; must be aligned on a 16-byte 
+ *            boundary. 
+ *   srcRefStep - width of the reference picture plane, in terms of full 
+ *            pixels; must be a multiple of 16. 
+ *   pRefRect - reference plane valid region rectangle, specified relative to 
+ *            the image origin 
+ *   pCurrPointPos - position of the current macroblock in the current plane 
+ *   pMESpec - pointer to the vendor-specific motion estimation specification 
+ *            structure; must be allocated and then initialized using 
+ *            omxVCM4P2_MEInit prior to calling this function. 
+ *   pMBInfo - array, of dimension four, containing pointers to information 
+ *            associated with four nearby MBs: 
+ *            -   pMBInfo[0] - pointer to left MB information 
+ *            -   pMBInfo[1] - pointer to top MB information 
+ *            -   pMBInfo[2] - pointer to top-left MB information 
+ *            -   pMBInfo[3] - pointer to top-right MB information 
+ *            Any pointer in the array may be set equal to NULL if the 
+ *            corresponding MB doesn't exist.  For each MB, the following structure 
+ *            members are used:    
+ *            -   mbType - macroblock type, either OMX_VC_INTRA, OMX_VC_INTER, or 
+ *                OMX_VC_INTER4V 
+ *            -   pMV0[2][2] - estimated motion vectors; represented 
+ *                in 1/2 pixel units 
+ *            -   sliceID - number of the slice to which the MB belongs 
+ *   pSrcDstMBCurr - pointer to information structure for the current MB.  
+ *            The following entries should be set prior to calling the 
+ *            function: sliceID - the number of the slice the to which the 
+ *            current MB belongs.  The structure elements cbpy and cbpc are 
+ *            ignored. 
+ *
+ * Output Arguments:
+ *   
+ *   pSrcDstMBCurr - pointer to updated information structure for the current 
+ *            MB after MB-level motion estimation has been completed.  The 
+ *            following structure members are updated by the ME function:   
+ *              -  mbType - macroblock type: OMX_VC_INTRA, OMX_VC_INTER, or 
+ *                 OMX_VC_INTER4V. 
+ *              -  pMV0[2][2] - estimated motion vectors; represented in 
+ *                 terms of 1/2 pel units. 
+ *              -  pMVPred[2][2] - predicted motion vectors; represented 
+ *                 in terms of 1/2 pel units. 
+ *            The structure members cbpy and cbpc are not updated by the function. 
+ *   pDstSAD - pointer to the minimum SAD for INTER1V, or sum of minimum SADs 
+ *            for INTER4V 
+ *   pDstBlockSAD - pointer to an array of SAD values for each of the four 
+ *            8x8 luma blocks in the MB.  The block SADs are in scan order for 
+ *            each MB. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments.  Returned if one or more of the 
+ *              following conditions is true: 
+ *    -    at least one of the following pointers is NULL: pSrcCurrBuf, 
+ *              pSrcRefBuf, pRefRect, pCurrPointPos, pMBInter, pMBIntra, 
+ *              pSrcDstMBCurr, or pDstSAD.

+ * Function:  omxVCM4P2_PredictReconCoefIntra   (6.2.5.4.3)
+ *
+ * Description:
+ * Performs adaptive DC/AC coefficient prediction for an intra block.  Prior 
+ * to the function call, prediction direction (predDir) should be selected as 
+ * specified in [ISO14496-2], subclause 7.4.3.1. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrcDst - pointer to the coefficient buffer which contains the quantized 
+ *            coefficient residuals (PQF) of the current block; must be 
+ *            aligned on a 4-byte boundary.  The output coefficients are 
+ *            saturated to the range [-2048, 2047]. 
+ *   pPredBufRow - pointer to the coefficient row buffer; must be aligned on 
+ *            a 4-byte boundary. 
+ *   pPredBufCol - pointer to the coefficient column buffer; must be aligned 
+ *            on a 4-byte boundary. 
+ *   curQP - quantization parameter of the current block. curQP may equal to 
+ *            predQP especially when the current block and the predictor block 
+ *            are in the same macroblock. 
+ *   predQP - quantization parameter of the predictor block 
+ *   predDir - indicates the prediction direction which takes one of the 
+ *            following values: OMX_VC_HORIZONTAL - predict horizontally 
+ *            OMX_VC_VERTICAL - predict vertically 
+ *   ACPredFlag - a flag indicating if AC prediction should be performed. It 
+ *            is equal to ac_pred_flag in the bit stream syntax of MPEG-4 
+ *   videoComp - video component type (luminance or chrominance) of the 
+ *            current block 
+ *
+ * Output Arguments:
+ *   
+ *   pSrcDst - pointer to the coefficient buffer which contains the quantized 
+ *            coefficients (QF) of the current block 
+ *   pPredBufRow - pointer to the updated coefficient row buffer 
+ *   pPredBufCol - pointer to the updated coefficient column buffer  Note: 
+ *            Buffer update: Update the AC prediction buffer (both row and 
+ *            column buffer). 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - bad arguments, if:
+ *        -    At least one of the pointers is NULL: 
+ *              pSrcDst, pPredBufRow, or pPredBufCol.

+ * prediction, and reconstructs the current intra block texture for prediction 
+ * on the next frame.  Quantized row and column coefficients are returned in 
+ * the updated coefficient buffers. 
+ *
+ * Input Arguments:
+ *   
+ *   pSrc - pointer to the pixels of current intra block; must be aligned on 
+ *            an 8-byte boundary. 
+ *   pPredBufRow - pointer to the coefficient row buffer containing 
+ *            ((num_mb_per_row * 2 + 1) * 8) elements of type OMX_S16. 
+ *            Coefficients are organized into blocks of eight as described 
+ *            below (Internal Prediction Coefficient Update Procedures).  The 
+ *            DC coefficient is first, and the remaining buffer locations 
+ *            contain the quantized AC coefficients. Each group of eight row 
+ *            buffer elements combined with one element eight elements ahead 
+ *            contains the coefficient predictors of the neighboring block 
+ *            that is spatially above or to the left of the block currently to 
+ *            be decoded. A negative-valued DC coefficient indicates that this 
+ *            neighboring block is not INTRA-coded or out of bounds, and 
+ *            therefore the AC and DC coefficients are invalid.  Pointer must 
+ *            be aligned on an 8-byte boundary. 
+ *   pPredBufCol - pointer to the prediction coefficient column buffer 
+ *            containing 16 elements of type OMX_S16. Coefficients are 
+ *            organized as described in section 6.2.2.5.  Pointer must be 
+ *            aligned on an 8-byte boundary. 
+ *   pSumErr - pointer to a flag indicating whether or not AC prediction is 
+ *            required; AC prediction is enabled if *pSumErr >=0, but the 
+ *            value is not used for coefficient prediction, i.e., the sum of 
+ *            absolute differences starts from 0 for each call to this 
+ *            function.  Otherwise AC prediction is disabled if *pSumErr < 0 . 
+ *   blockIndex - block index indicating the component type and position, as 
+ *            defined in [ISO14496-2], subclause 6.1.3.8. 
+ *   curQp - quantization parameter of the macroblock to which the current 
+ *            block belongs 
+ *   pQpBuf - pointer to a 2-element quantization parameter buffer; pQpBuf[0] 
+ *            contains the quantization parameter associated with the 8x8 
+ *            block left of the current block (QPa), and pQpBuf[1] contains 
+ *            the quantization parameter associated with the 8x8 block above 
+ *            the current block (QPc).  In the event that the corresponding 
+ *            block is outside of the VOP bound, the Qp value will not affect 
+ *            the intra prediction process, as described in [ISO14496-2], 
+ *            sub-clause 7.4.3.3,  Adaptive AC Coefficient Prediction.  
+ *   srcStep - width of the source buffer; must be a multiple of 8. 
+ *   dstStep - width of the reconstructed destination buffer; must be a 
+ *            multiple of 16. 
+ *   shortVideoHeader - binary flag indicating presence of 
+ *            short_video_header; shortVideoHeader==1 selects linear intra DC 
+ *            mode, and shortVideoHeader==0 selects non linear intra DC mode. 
+ *
+ * Output Arguments:
+ *   
+ *   pDst - pointer to the quantized DCT coefficient buffer; pDst[0] contains 
+ *            the predicted DC coefficient; the remaining entries contain the 
+ *            quantized AC coefficients (without prediction).  The pointer 
+ *            pDstmust be aligned on a 16-byte boundary. 
+ *   pRec - pointer to the reconstructed texture; must be aligned on an 
+ *            8-byte boundary. 
+ *   pPredBufRow - pointer to the updated coefficient row buffer 
+ *   pPredBufCol - pointer to the updated coefficient column buffer 
+ *   pPreACPredict - if prediction is enabled, the parameter points to the 
+ *            start of the buffer containing the coefficient differences for 
+ *            VLC encoding. The entry pPreACPredict[0]indicates prediction 
+ *            direction for the current block and takes one of the following 
+ *            values: OMX_VC_NONE (prediction disabled), OMX_VC_HORIZONTAL, or 
+ *            OMX_VC_VERTICAL.  The entries 
+ *            pPreACPredict[1]-pPreACPredict[7]contain predicted AC 
+ *            coefficients.  If prediction is disabled (*pSumErr<0) then the 
+ *            contents of this buffer are undefined upon return from the 
+ *            function 
+ *   pSumErr - pointer to the value of the accumulated AC coefficient errors, 
+ *            i.e., sum of the absolute differences between predicted and 
+ *            unpredicted AC coefficients 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - Bad arguments:
+ *    -    At least one of the following pointers is NULL: pSrc, pDst, pRec, 
+ *         pCoefBufRow, pCoefBufCol, pQpBuf, pPreACPredict, pSumErr. 
+ *    -    blockIndex < 0 or blockIndex >= 10; 
+ *    -    curQP <= 0 or curQP >= 32. 
+ *    -    srcStep, or dstStep <= 0 or not a multiple of 8. 
+ *    -    pDst is not 16-byte aligned: . 
+ *    -    At least one of the following pointers is not 8-byte aligned: 
+ *         pSrc, pRec.  
+ *
+ *  Note: The coefficient buffers must be updated in accordance with the 
+ *        update procedures defined in section in 6.2.2.

+            bytes are present in the stream.
+
+            Stream buffer is assumed to contain either exactly one NAL unit

+            stream format described in the Annex B of the standard. Function

+
+        Functional description:
+            Perform error concealment for a picture. Two types of concealment
+            is performed based on sliceType:
+                1) copy from previous picture for P-slices.
+                2) concealment from neighbour pixels for I-slices
+
+            I-type concealment is based on ideas presented by Jarno Tulkki.
+            The concealment algorithm determines frequency domain coefficients
+            from the neighbour pixels, applies integer transform (the same
+            transform used in the residual processing) and uses the results as
+            pixel values for concealed macroblocks. Transform produces 4x4
+            array and one pixel value has to be used for 4x4 luma blocks and
+            2x2 chroma blocks.
+
+            Similar concealment is performed for whole picture (the choise
+            of the type is based on last successfully decoded slice header of
+            the picture but it is handled by the calling function). It is
+            acknowledged that this may result in wrong type of concealment
+            when a picture contains both types of slices. However,
+            determination of slice type macroblock-by-macroblock cannot
+            be done due to the fact that it is impossible to know to which
+            slice each corrupted (not successfully decoded) macroblock
+            belongs.
+
+            The error concealment is started by searching the first propoerly
+            decoded macroblock and concealing the row containing the macroblock
+            in question. After that all macroblocks above the row in question
+            are concealed. Finally concealment of rows below is performed.
+            The order of concealment for 4x4 picture where macroblock 9 is the
+            first properly decoded one is as follows (properly decoded
+            macroblocks marked with 'x', numbers indicating the order of
+            concealment):
+
+               4  6  8 10
+               3  5  7  9
+               1  x  x  2
+              11 12 13 14
+
+            If all macroblocks of the picture are lost, the concealment is
+            copy of previous picture for P-type and setting the image to
+            constant gray (pixel value 128) for I-type.
+
+            Concealment sets quantization parameter of the concealed
+            macroblocks to value 40 and macroblock type to intra to enable
+            deblocking filter to smooth the edges of the concealed areas.
+
+        Inputs:
+            pStorage        pointer to storage structure

+            Decode unsigned Exp-Golomb code. This is the same as codeNum used
+            in other Exp-Golomb code mappings. Code num (i.e. the decoded
+            symbol) is determined as
+
+                codeNum = 2^leadingZeros - 1 + GetBits(leadingZeros)
+
+            Normal decoded symbols are in the range [0, 2^32 - 2]. Symbol
+            2^32-1 is indicated by BIG_CODE_NUM with return value HANTRO_OK
+            while symbol 2^32  is indicated by BIG_CODE_NUM with return value
+            HANTRO_NOK.  These two symbols are special cases with code length
+            of 65, i.e.  32 '0' bits, a '1' bit, and either 0 or 1 represented
+            by 32 bits.
+
+            Symbol 2^32 is out of unsigned 32-bit range but is needed for
+            DecodeExpGolombSigned to express value -2^31.

+ * CameraHardwareInterface.h defines the interface to the

+ *
+ * It is a referenced counted interface with RefBase as its base class.
+ * CameraService calls openCameraHardware() to retrieve a strong pointer to the
+ * instance of this interface and may be called multiple times. The
+ * following steps describe a typical sequence:
+ *
+ *   -# After CameraService calls openCameraHardware(), getParameters() and
+ *      setParameters() are used to initialize the camera instance.
+ *      CameraService calls getPreviewHeap() to establish access to the
+ *      preview heap so it can be registered with SurfaceFlinger for
+ *      efficient display updating while in preview mode.
+ *   -# startPreview() is called.  The camera instance then periodically
+ *      sends the message CAMERA_MSG_PREVIEW_FRAME (if enabled) each time
+ *      a new preview frame is available.  If data callback code needs to use
+ *      this memory after returning, it must copy the data.
+ *
+ * Prior to taking a picture, CameraService calls autofocus(). When auto
+ * focusing has completed, the camera instance sends a CAMERA_MSG_FOCUS notification,
+ * which informs the application whether focusing was successful. The camera instance
+ * only sends this message once and it is up  to the application to call autoFocus()
+ * again if refocusing is desired.
+ *
+ * CameraService calls takePicture() to request the camera instance take a
+ * picture. At this point, if a shutter, postview, raw, and/or compressed callback
+ * is desired, the corresponding message must be enabled. As with CAMERA_MSG_PREVIEW_FRAME,
+ * any memory provided in a data callback must be copied if it's needed after returning.
