Nils Wallménius c45e1254c6 FS#11454 Tuning of codec compiler options 
Tested with h300 and sansa c200v1

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

c200v1 speedups:
alac: 1.5%
wma 3-4%
wavpack 2%

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
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

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

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

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
