Jens Arnold ed945e31c1 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. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19556 a1c6a512-1295-4272-9138-f99709370657		2008-12-22 08:33:49 +00:00

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).	2008-11-24 18:40:49 +00:00

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.	2008-12-02 02:26:04 +00:00

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%.	2007-10-19 21:35:07 +00:00
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).	2008-11-28 23:50:22 +00:00

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().	2008-11-19 21:31:33 +00:00
