Michael Sevakis	d4e904bf35	SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12472 a1c6a512-1295-4272-9138-f99709370657	2007-02-24 17:06:36 +00:00
Michael Sevakis	36175ac945	SWCODEC: DSP optimizations for conversion to internal format and resampling. Assembly resampling for Coldfire. Word has it ARM will get that soon. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12399 a1c6a512-1295-4272-9138-f99709370657	2007-02-19 02:49:26 +00:00
Thom Johansen	56f2ca74ad	Assembler optimised crossfeed routine for ARM. Performance improvement is 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	2006-08-16 12:38:49 +00:00
Thom Johansen	cc94ae45a7	Keep assembler versions of DSP routines in dsp_arch.S files. This also ... solves the annoying register allocator problem when not using -fomit-frame-pointer for the Coldfire assembler optimised crossfeed routine. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9215 a1c6a512-1295-4272-9138-f99709370657	2006-03-23 19:59:52 +00:00
