Makefile Seeking and resume support for Monkey's Audio 2007-06-08 22:35:26 +00:00
parser.c Define and use a local APE_MAX function to make the standalone demac decoder compile again. 2007-06-09 00:58:15 +00:00

predictor-arm.S Don't use ldrd/strd on ARMv5 since not all revisions support them and the gain from using them is minimal (basically code size only). 2009-07-17 09:17:54 +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
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

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 Use all available codec iram for reciprocal table in APE codec on ARMv4. Done by linking first with the table empty to determine free space, then sizing table to fill it. 2010-02-04 08:45:38 +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_math_generic.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
