2008-11-05Codec lib directories renamed, except for demac.Björn Stenberg
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19018 a1c6a512-1295-4272-9138-f99709370657
2008-09-04Combine the Vorbis, WMA and AAC IMDCT functions and put them into the ↵Michael Giacomelli
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
2006-09-05Recude iram usage for the Vorbis decoder a little. Makes it possible to ↵Magnus Holmgren
build with gcc 4.0.3. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10891 a1c6a512-1295-4272-9138-f99709370657
2005-12-28Vorbis optimizations from Brandon Low (part of patch 1387611). Reduces cpu ↵Magnus Holmgren
boost ratio on a test track by about 6 percentage points. Also fixes broken simulator playback caused by my previous Tremor commit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8291 a1c6a512-1295-4272-9138-f99709370657
2005-06-10A little improvement on Vorbis block synthesis.Pedro Vasconcelos
Added myself to the list of contributors. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6664 a1c6a512-1295-4272-9138-f99709370657
2005-06-08Vorbis opts: keep floor1 lookup table in IRAM.Pedro Vasconcelos
Slightly faster 16-bit clipping function. Misc: changed tabs for spaces to conform with Rockbox coding standards. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6608 a1c6a512-1295-4272-9138-f99709370657
2005-06-06Vorbis optimizations: allocation of PCM buffers in IRAM, avoiding copying.Pedro Vasconcelos
Slight code improvements to the MDCT functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6590 a1c6a512-1295-4272-9138-f99709370657
2005-05-27Basic optimizations of the Vorbis decoder for the ihp-1x0.Pedro Vasconcelos
Capable of real-time decoding with cpu freq at 120mhz. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6527 a1c6a512-1295-4272-9138-f99709370657

others), to make plugins work properly in the simulator. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6086 a1c6a512-1295-4272-9138-f99709370657
