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.

Put back the insane buffer where it belongs on non-ARM, and simplify the selection.

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.

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.

Improvements to specialized dividers for APE codec:

2010-01-28T02:28:52+00:00

* Use Newton-Raphson divider on ARMv5e and ARMv6, about 7% speedup on Gigabeat S.
* On ARMv4 targets using IRAM, remove insane filter buffer from IRAM, fill available IRAM with LUT of reciprocals for small divisors - speedup varies according to target and available IRAM, APE normal sample is approx. 109% RT on e200.
* Rename apps/codecs/lib/udiv32_armv4.S to apps/codecs/lib/udiv32_arm.S, which includes dividers for all ARM targets specialized for APE.

Make the codecs use more IRAM on S5L870x, as we have plenty of it.

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).

New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles.

2008-11-20T11:27:31+00:00

Many #include lines adjusted to conform to the new standards.
