h300 speedups:
a52: 2%
cook: 9-17%
aac: 0.5%
vorbis: 0.5%
wma: 6-12%

c200v1 speedups:

tlsf Rename/change SIMVER to APP_TYPE in the Makefiles. 2010-07-10 13:49:49 +00:00
asm_arm.h ARMv6 versions of X(N)PROD31 macros and MULT32 macro. Saves about 1MHz or 3% decoding vorbis on gigabeat S. 2010-06-17 15:24:23 +00:00
asm_mcf5249.h Remove CLIP_TO_15 from codeclib. Remove tabs. 2010-02-21 22:05:48 +00:00
codeclib.c Remove some sample functions from codeclib - these were for verifying the generated asm for bs_generic and never intended for use. 2009-12-09 17:13:06 +00:00
codeclib.h Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 2010-05-06 21:04:40 +00:00
codeclib_misc.h Check if ROCKBOX_LITTLE_ENDIAN and ROCKBOX_BIG_ENDIAN are defined, no which value they have 2010-07-14 20:19:44 +00:00
ffmpeg_bitstream.c Begin shoehorning wma into the clip codec buffer again. Reduce the static buffer used by init_vlc so that it is no larger than is needed. Make the VLCcode struct packed to save space. 2010-07-17 08:33:36 +00:00
ffmpeg_bswap.h Remove all tabs within codec path. 2010-02-22 19:44:05 +00:00
ffmpeg_get_bits.h Enable ff_copy_bits in ffmpeg_bitstream.c and put_bits.h and intreadwrite.h to codeclib. 2010-07-17 07:46:38 +00:00
ffmpeg_intreadwrite.h Enable ff_copy_bits in ffmpeg_bitstream.c and put_bits.h and intreadwrite.h to codeclib. 2010-07-17 07:46:38 +00:00
ffmpeg_put_bits.h Enable ff_copy_bits in ffmpeg_bitstream.c and put_bits.h and intreadwrite.h to codeclib. 2010-07-17 07:46:38 +00:00
fft-ffmpeg.c Remove all tabs within codec path. 2010-02-22 19:44:05 +00:00
fft-ffmpeg_arm.h Fix inline asm argument. Shouldn't have much impact in practice but might save a load if gcc is clever. 2010-06-27 15:15:46 +00:00
fft.h Merge from branches/mdctexp - faster ifft+imdct in codec lib 2010-02-17 00:49:53 +00:00
fixedpoint.c Take 2 at 'Consolidate all fixed point math routines in one library' (FS#10400) by Jeffrey Goode 2009-07-05 18:06:07 +00:00
fixedpoint.h * FS#10411 - Fixed point math code is bloated by Jeffrey Goode 2009-07-07 13:36:34 +00:00
libcodec.make FS#11454 Tuning of codec compiler options 2010-07-18 19:05:53 +00:00
mdct.c Some asm for mdct on coldfire, speeds up vorbis decoding by about 0.3MHz 2010-05-13 08:03:42 +00:00
mdct.h Remove unused GPL code from ffmpeg mdct library in order to restore it to LGPL. 2010-03-05 21:37:46 +00:00
mdct2.c Improved bitrev12, using a larger LUT to save one lookup, speeds up vorbis about 2% on beast, about 0.5% on h300 2009-12-13 15:00:20 +00:00
mdct2.h Modify the mdct library to enable using it outside rockbox - No functional changes. 2009-08-13 20:02:31 +00:00
mdct_arm.S FS#11335 by me: make ARM assembly functions thumb-friendly 2010-06-11 04:41:36 +00:00
mdct_lookup.c Merge from branches/mdctexp - faster ifft+imdct in codec lib 2010-02-17 00:49:53 +00:00
mdct_lookup.h Merge from branches/mdctexp - faster ifft+imdct in codec lib 2010-02-17 00:49:53 +00:00
osx.dummy.c
setjmp.h Remove all tabs within codec path. 2010-02-22 19:44:05 +00:00
setjmp_arm.S Use bx lr unconditionally in setjmp_arm.S 2010-03-09 00:22:23 +00:00
setjmp_cf.S Remove all tabs within codec path. 2010-02-22 19:44:05 +00:00
setjmp_mips.S
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
