Pathname: PVMP4AudioDecoderGetMemRequirements.c
------------------------------------------------------------------------------
REVISION HISTORY
Description: Copied from aac_decode_frame
Description: Cleaned up.
Description: (1) use UInt32 to replace size_t type
(2) memory of tDec_Int_File is splitted into 3 pieces,
sizeof(tDec_Int_File) is only part of the total memory
required. The additional memory required to decode per
channel information is allocated by a DPI call outside this
API
Who: Date: MM/DD/YYYY
Description:
------------------------------------------------------------------------------
INPUT AND OUTPUT DEFINITIONS
Inputs: None
Local Stores/Buffers/Pointers Needed: None
Global Stores/Buffers/Pointers Needed: None
Outputs:
size = amount of memory needed to be allocated by the calling
environment.
Pointers and Buffers Modified: None
Local Stores Modified: None
Global Stores Modified: None
------------------------------------------------------------------------------
FUNCTION DESCRIPTION
This function returns the amount of internal memory needed by the library.
Presently this is a constant value, but could later be more sophisticated
by taking into account mono or stereo, and whether LTP is to be used.

PSEUDO-CODE
size = sizeof(tDec_Int_File);
RETURN (size)
------------------------------------------------------------------------------
RESOURCES USED
When the code is written for a specific target processor the
the resources used should be documented below.
STACK USAGE: [stack count for this module] + [variable to represent
stack usage for each subroutine called]
where: [stack usage variable] = stack usage for [subroutine
name] (see [filename].ext)
DATA MEMORY USED: x words
PROGRAM MEMORY USED: x words
CLOCK CYCLES: [cycle count equation for this module] + [variable
used to represent cycle count for each subroutine
called]
where: [cycle count variable] = cycle count for [subroutine
name] (see [filename].ext)
