Andree Buschmann 07405841c6 FS#12463: Improve performance for multichannel FLAC decoding. Speeds up decoding by 3 MHz on PP5022, 6-7 MHz on S5L870x and 11-12 MHz on MCF5250. 5.1-88kHz-files still do not decode in realtime on Coldfire and PP502x. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31367 a1c6a512-1295-4272-9138-f99709370657		2011-12-19 19:46:10 +00:00
..
arm.h	Revert r25929. Test have shown that the assembler code is more than 50% faster than the C code both on ARM7TDMI (tested on PP5002 and PP5022) and on ARM1136JF-S (tested on Gigabeat S). If it is slower on ARM9*, it should be disabled for ARM9 only.	2010-05-10 19:05:25 +00:00

bitstream.h	FS#12463: Improve performance for multichannel FLAC decoding. Speeds up decoding by 3 MHz on PP5022, 6-7 MHz on S5L870x and 11-12 MHz on MCF5250. 5.1-88kHz-files still do not decode in realtime on Coldfire and PP502x.	2011-12-19 19:46:10 +00:00

decoder.h	Fix decoding of multichannel flac, refactor sample buffer handling and decorrelation (taken from ffmpeg sources) and add some flac details to the manual. Solves FS#12371.	2011-12-10 22:28:16 +00:00

shndec.c	Use __builtin_constant_p() to select the best byteswapping method: constant or target optimized. Same macro can then be used for constant values and inits as well as non-constant.	2011-01-30 00:58:45 +00:00
shndec.h
SOURCES	Sync codeclib bitstream code with upstream ffmpeg code. Build ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code. Speeds up cook decoding by 2-3% on h300 and flac by 25% on h300, also speeds up flac decoding by 2% on c200 (decoding speed of cook on c200 is unchanged).	2010-07-15 16:19:17 +00:00
