Michael Giacomelli	46f85c4c54	Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18412 a1c6a512-1295-4272-9138-f99709370657	2008-09-04 18:02:10 +00:00
Tomasz Malesinski	c13eba29ff	FS #7833: Optimizations to the Vorbis codec: ... - ARM assembly version of parts of mdct, - special case for vorbis_book_decodevv_add for 2 channels and even book->dim, - store the output in vb->pcm if possible, as it is usually in IRAM as opposed to v->pcm. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14875 a1c6a512-1295-4272-9138-f99709370657	2007-09-27 21:58:51 +00:00
