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

algorithm is best for spoken word. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21258 a1c6a512-1295-4272-9138-f99709370657

2008-03-19Commit FS#8750. Add ARM assembler for the dsp-functions ↵Andree Buschmann
channels_process_sound_chan_mono(), channels_process_sound_chan_karaoke(), sample_output_mono() and sample_output_stereo(). By measurement the speed up is ~75% for the first three functions and ~40% for sample_output_stereo(). Additionally avoid calling yield() to often in dsp.c -- it is now limited to once per tick. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16717 a1c6a512-1295-4272-9138-f99709370657
2007-03-11ARM assembler for resampling. Should provide some gains, though not huge ones.Thom Johansen

SWITCHPARAM cruft as it's no longer needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12507 a1c6a512-1295-4272-9138-f99709370657
2006-08-16Assembler optimised crossfeed routine for ARM. Performance improvement is ↵Thom Johansen
more than double. Should work fine, but watch your ears nevertheless. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10608 a1c6a512-1295-4272-9138-f99709370657
