2010-05-02Gigabeat S: Reduce stalling in the ARMv6 IDCT. Also save one instruction per ↵Jens Arnold
loop, and fix comments. Speeds up fullscreen video decoding by about 5% (excluding video output). Still not perfect... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25775 a1c6a512-1295-4272-9138-f99709370657

2009-07-12* Fix overlooked r12 usage possibility in mpegplayer ARM idct Jens Arnold
* ARM dualcore: Don't save r12 in switch_thread_core() git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21830 a1c6a512-1295-4272-9138-f99709370657
2009-07-12* ARM asm DSP and codec/plugin functions: Use r12 scratch register properlyJens Arnold
* Fix saving another unused reg in dsp code * Use less regs in the generic ARM mpegplayer adding idct pure DC case * Fix ARMv6 mpegplayer adding idct using an unsaved register in pure DC case git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21803 a1c6a512-1295-4272-9138-f99709370657
2009-06-20Faster idct for ARMv6. Overall mpegplayer speedup is quite minimal though.Jens Arnold
