decoder.h
Calculate watermark from bitrate and harddisk spinup time.

demac_config.h
Branch optimisation in both C (giving hints to gcc - verified using -fprofile-arcs and gcov) and asm files. Biggest effect on coldfire (-c1000: +8%, -c2000: +5%), but ARM also profits a bit (less than 1% on ARM7TDMI, around 1% on ARM1136).

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
Slight speedup for the APE filters. Most noticeable on coldfire (+3.5% for -c2000), but also helps on the arm targets (+0.9% for -c2000 on PP5002). This transformation is oveflow safe, as absres < 2^24 is guaranteed.

predictor-arm.S
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-cf.S
Implement mono predictor in assembler for coldfire, yielding a ~6% speedup for mono -c1000. Apply ideas gained from it back to the stereo predictor, saving 4 instructions. No speed increase for stereo, probably due to cache aliasing effects. * 80-column police.

SOURCES
APE codec: Assembler optimised predictor for coldfire. Heavily based on the arm version atm, instruction reordering will probably allow for a bit more speedup soon. Speedup: -c1000: 177% -> 210%, -c2000: 135% -> 147%, -c3000: 97% -> 103%.

vector_math16_armv5te.h
Resurrect the ARM7 16-bit packed vector addition/subtraction for ARMv5, giving a nice speedup for the higher compression levels (tested on Cowon D2).

vector_math16_armv6.h
Tweak the ARMv6 filter assembly a bit further.

vector_math16_cf.h
Several tweaks and cleanups: * Use .rept instead of repeated macros for repeating blocks. * Use MUL (variant) instead of MLA (variant) in the first step of the ARM scalarproduct() if there's no loop. * Unroll ARM assembler functions to 32 where not already done, plus the generic scalarproduct().
