Nils Wallménius 71ad3679dc codeclib: inline assembler for fft4 and fft8 on coldfire, small 0.2-0.3MHz speedup with gcc 3.4, larger 0.6-0.8MHz speedup with gcc 4.4/4.5

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 codeclib: there is no need to limit the outputs of the coldfire X(N)PROD_R macros to data registers, no significant speed diff 2010-11-24 12:01:08 +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 Make codeclib_misc.h include the asm headers to simplify inclusion magic. 2010-07-29 12:52:04 +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 ARMv6 supports unaligned memory accesses and they are enabled on our only ARMv6 target so we might as well use them. Speeds up decoding of a flac8 file by 3.5%. 2010-09-29 13:20:03 +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 codeclib: inline assembler for fft4 and fft8 on coldfire, small 0.2-0.3MHz speedup with gcc 3.4, larger 0.6-0.8MHz speedup with gcc 4.4/4.5 2010-12-01 11:27:30 +00:00
fft-ffmpeg_arm.h Rearrange and remove some manual register assignments, make use of pointer address increments for free on arm, and remove macros in favour of explicit inline fns. also add memory clobbers to all uses of stm in inline asm. appears to resolve issues with codeclib failing to work as expected when using ARM_ASM optimisations on targets with native position independent code (e.g. android rockbox targets, but also tremor on non-rockbox targets that has been patched with the fastermdct patches) 2010-10-12 23:29:17 +00:00
fft-ffmpeg_cf.h codeclib: inline assembler for fft4 and fft8 on coldfire, small 0.2-0.3MHz speedup with gcc 3.4, larger 0.6-0.8MHz speedup with gcc 4.4/4.5 2010-12-01 11:27:30 +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
