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. 2008-12-22 08:33:49 +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
