2011-05-12libfaad: AAC including HE-profile needs ~470 KB for playback (measured on ↵Andree Buschmann
ARM). Therefor it does not make sense to enable HE on devices with CODEC_SIZE < 512 KB. This will allow to load and play larger AAC-LC files on such devices. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29862 a1c6a512-1295-4272-9138-f99709370657
2011-04-24Rework of libfaad in several areas. Allow removal of malloc with a new ↵Andree Buschmann
define FAAD_STATIC_ALLOC (in common.h). For now malloc is not fully removed but used by a few arrays needed for AAC-HE SBR+PS only. Reason to keep malloc is to have this amount of memory available for AAC-LC files which might require large m4a tables. The changes make the allocation routines much smaller, better centralized and allow to move duplicated code from aac.c/raa.c to libfaad. The rework includes removal of (now and former) unused code as well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29778 a1c6a512-1295-4272-9138-f99709370657

2010-09-14Further libfaad cleanup. Make libfaad compilable for floating point. ↵Andree Buschmann
Floating point cannot be used as reference though, as errorous noise is the result. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28071 a1c6a512-1295-4272-9138-f99709370657

2010-07-01Submit FS#11445. Speed up of faad (aac) decoder via several optimizations ↵Andree Buschmann
like refactoring some requantization routines, moving several arrays and code tables to IRAM, using an optimized swap32() function and inlining several huffman decoder functions. Decoding is sped up by ~10% (PP5002, PP5022, MCF5249) and ~22% (MCF5250). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27225 a1c6a512-1295-4272-9138-f99709370657
2010-05-06Move c/h files implementing/defining standard library stuff into a new libc ↵Thomas Martitz
directory, also standard'ify some parts of the code base (almost entirely #include fixes). This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657
2009-12-13Libfaad pow2/log2 improvements:Andrew Mahone
Correct pow2_* to calculate correct output for input < 0.0 or between 0.0 and 1.0 instead of returning 0. This will change output, but the float version of this codec uses pow(2.0,x) in place of these functions, so this behavior was probably a bug Replace 64-bit multiply in pow2_* with left or right shift by whole part of input, rounding if shifting right. An ARM-specific optimized version is provided as a C inline function, other targets use a C macro. Increase constant size of table for pow2 to improve accuracy, also avoid early truncation in linear interpolation of result. Move constant tables for pow2 and log2 to iram. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23967 a1c6a512-1295-4272-9138-f99709370657
2009-12-09Extend av_log2 in codeclib into a generic for scanning for set bits, which ↵Andrew Mahone
can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23903 a1c6a512-1295-4272-9138-f99709370657

introduced by this. Enable compiling the AAC codec on the Clip. Due to lack of memory for seek tables, files over 10 minutes long or so will probably fail. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20781 a1c6a512-1295-4272-9138-f99709370657
