Fixed-point HE-AAC decoder Developed by RealNetworks, 2005===============================Overview--------This module contains a high-performance HE-AAC decoder for 32-bit fixed-point processors. The following is a summary of what is and is not supported:Supported: - MPEG2, MPEG4 low complexity decoding (intensity stereo, M-S, TNS, PNS) - spectral band replication (SBR), high-quality mode - mono, stereo, and multichannel modes - ADTS, ADIF, and raw data block file formatsNot currently supported: - main or SSR profile, LTP - coupling channel elements (CCE) - 960/1920-sample frame size - low-power mode SBR - downsampled (single-rate) SBR - parametric stereoHighlights - highly optimized for ARM processors (details in docs/ subdirectory) - reference x86 implementation - C and assembly code only (C++ not required for codec library) - reentrant, statically linkable - low memory (details in docs/ subdirectory) - option to use Intel Integrated Performance Primitives (details below)Supported platforms and toolchainsThis codec should run on any 32-bit fixed-point processor which can perform a full 32x32-bit multiply (providing a 64-bit result). The following processors and toolchains are supported: - x86, Microsoft Visual C++ - x86, GNU toolchain (gcc) - ARM, ARM Developer Suite (ADS) - ARM, Microsoft Embedded Visual C++ - ARM, GNU toolchain (gcc)ARM refers to any processor supporting ARM architecture v.4 or above. Thumb is not required.Generally ADS produces the fastest code. EVC 3 does not support inline assembly code for ARM targets, so calls to MULSHIFT32 (smull on ARM) are left as function calls. This incurs a significant performance penalty. For the fastest code on targets which do not normally use ADS consider compiling with ADS, using the -S option to output assembly code, and feeding this assembly code to the assem
