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. + +------------------------------------------------------------------------------ + REQUIREMENTS + + None + +------------------------------------------------------------------------------ + REFERENCES + + [1] "AMR Speech Codec Frame Structure", 3GPP TS 26.101 version 4.1.0 + Release 4, June 2001 + +------------------------------------------------------------------------------ + PSEUDO-CODE + + Note: AMRSID_RXTYPE_BIT_OFFSET = 35 + AMRSID_RXMODE_BIT_OFFSET = 36 + NUM_AMRSID_RXMODE_BITS = 3 + + + // Set up Decoder state structure pointer + Speech_Decode_FrameState *decoder_state + = (Speech_Decode_FrameState *) state_data + + // Determine type of de-formatting + + // Decode WMF or IF2 frames + IF ((input_format == AMR_RX_WMF) | (input_format == AMR_RX_IF2)) + THEN + IF (input_format == AMR_RX_WMF) + THEN + // Convert incoming packetized raw WMF data to ETS format + CALL wmf_to_ets(frame_type = frame_type + input_ptr = speech_bits_ptr + output_ptr = &dec_ets_input_bfr) + MODIFYING(nothing) + RETURNING(nothing) + + // Address offset of the start of next frame + byte_offset = WmfDecBytesPerFrame[frame_type] + + ELSEIF (input_format == AMR_RX_IF2) + THEN + // Convert incoming packetized raw IF2 data to ETS format + CALL if2_to_ets(frame_type = frame_type + input_ptr = speech_bits_ptr + output_ptr = &dec_ets_input_bfr) + MODIFYING(nothing) + RETURNING(nothing) + + // Address offset of the start of next frame + byte_offset = If2DecBytesPerFrame[frame_type] + + ENDIF + + // Determine AMR codec mode and AMR RX frame type + IF (frame_type <= AMR_122) + THEN + mode = (enum Mode) frame_type;

+------------------------------------------------------------------------------ + 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.
