decoder.h Calculate watermark from bitrate and harddisk spinup time. 2009-01-10 21:10:56 +00:00
demac.h Calculate watermark from bitrate and harddisk spinup time. 2009-01-10 21:10:56 +00:00
demac_config.h Move (small) data into DRAM on PP5020, it's ~4.5% faster that way. Closes about half of the performance gap towards PP5022. The (relatively large) buffers for decoded data stay in IRAM, as does the reciprocal table. Clarify some comments. 2010-03-10 21:39:12 +00:00
entropy.c Move (small) data into DRAM on PP5020, it's ~4.5% faster that way. Closes about half of the performance gap towards PP5022. The (relatively large) buffers for decoded data stay in IRAM, as does the reciprocal table. Clarify some comments. 2010-03-10 21:39:12 +00:00
entropy.h Get rid of unused return values, except the one from decode_chunk() which will be used in the dual core split. 2008-11-26 18:01:18 +00:00
filter.c libdemac: ARMv7 assembler optimisation for the filters, tested on Nokia N900. Speedup is 2.1x for -c5000 compared to the ARMv6 asm. Note that actually compiling it on device requires hand-assembling the 'vadd' and 'vsub' instructions due to a bug in binutils 2.18.50, and making the standalone decoder use it requires Makefile and demac_config.h hacks. 2010-08-30 06:31:47 +00:00
filter.h libdemac: Separate filtering calls per channel in preparation for the dual-core split on PP. This also means less inlining, and hence speeds up decoding on single core slightly, due to better caching behaviour. 2010-03-03 21:20:13 +00:00
filter_16_11.c Calculate watermark from bitrate and harddisk spinup time. 2009-01-10 21:10:56 +00:00
filter_32_10.c Calculate watermark from bitrate and harddisk spinup time. 2009-01-10 21:10:56 +00:00
filter_64_11.c Calculate watermark from bitrate and harddisk spinup time. 2009-01-10 21:10:56 +00:00
filter_256_13.c Improve libdemac SATURATE slightly on ARMv4/5, move filter buffers and code out of IRAM for sizes that aren't near realtime and extend udiv32_arm reciprocal table. 2010-01-30 02:20:54 +00:00
filter_1280_15.c Improve libdemac SATURATE slightly on ARMv4/5, move filter buffers and code out of IRAM for sizes that aren't near realtime and extend udiv32_arm reciprocal table. 2010-01-30 02:20:54 +00:00
parser.c 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
parser.h Fix decoding of stereo frames with silence in only one channel. * Make the standalone decoder contain debugging information. 2008-12-21 23:49:02 +00:00
predictor-arm.S FS#11335 by me: make ARM assembly functions thumb-friendly 2010-06-11 04:41:36 +00:00
predictor-cf.S Fix typo from r28026 causing warnings on newer gcc. 2010-11-01 21:37:57 +00:00
predictor.c Assembler optimised mono predictor for ARM. Speedup for -c1000 mono is ~5% on PP, ~8% on Gigabeat S (less for higher compression levels). Also fix some overlooked comments in the stereo predictor. 2008-12-09 23:20:59 +00:00
predictor.h Get rid of unused return values, except the one from decode_chunk() which will be used in the dual core split. 2008-11-26 18:01:18 +00:00
SOURCES Move udiv32_arm.S into libdemac, as this divider is specialized for the APE codec and an optimized divider is already provided for general use in codeclib. 2010-02-04 05:49:37 +00:00
udiv32_arm-pre.S Fix yellow: add newline at EOF in udiv32_arm-pre.S 2010-02-04 08:55:36 +00:00
udiv32_arm.S Clarify comments in ARMv6 divider regarding special-case handling of large (high bit set) numerators. 2010-02-20 06:29:23 +00:00
vector_math16_armv5te.h Correction to clobber lists of several codec's inline assembly. 2010-05-29 15:00:10 +00:00
vector_math16_armv6.h Correction to clobber lists of several codec's inline assembly. 2010-05-29 15:00:10 +00:00
vector_math16_armv7.h libdemac: ARMv7 assembler optimisation for the filters, tested on Nokia N900. Speedup is 2.1x for -c5000 compared to the ARMv6 asm. Note that actually compiling it on device requires hand-assembling the 'vadd' and 'vsub' instructions due to a bug in binutils 2.18.50, and making the standalone decoder use it requires Makefile and demac_config.h hacks. 2010-08-30 06:31:47 +00:00
vector_math16_cf.h Get rid of .rept in inline asm() blocks where possible. Using .rept causes gcc to wrongly estimate the size of the asm(), leading to (potential) compilation problems. This is necessary for the upcoming restructuring, and should fix ARMv6+ sim builds as well. No functional change. 2010-03-03 20:52:02 +00:00
vector_math16_mmx.h Make libdemac compile again on OSX x86 and x86_64 by replacing .rept with fancy preprocessor stuff. 2010-07-19 10:04:54 +00:00
