rockbox/apps/codecs/libfaad/cfft.c, branch master My Rockbox tree 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. 2008-09-04T18:02:10+00:00 Michael Giacomelli giac2000@hotmail.com 2008-09-04T18:02:10+00:00 46f85c4c547188d08fd90bad7734d38c654f13ea git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18412 a1c6a512-1295-4272-9138-f99709370657

Revert the buggy warning fix for gcc 4.2. It caused a sim built with gcc 4.2 to segfault. Get rid of the warning by introducing a temporary variable instead. Obviously the cfft1(pos|neg)() call is too complex for gcc 4.2 to cope without that tempvar. Oh well... 2008-02-12T19:57:26+00:00 Jens Arnold amiconn@rockbox.org 2008-02-12T19:57:26+00:00 99db6dbafe4b151d960499b1dcf032f9e4797dbe git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16292 a1c6a512-1295-4272-9138-f99709370657

Revert previous 'fix'. Did not actually fix the warning as I wasn't paying attention. 2007-12-09T03:54:12+00:00 Dan Everton dan@iocaine.org 2007-12-09T03:54:12+00:00 19f487b451b026833a6d9aaeabcec756c9e9f2b7 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15899 a1c6a512-1295-4272-9138-f99709370657

Apply a bunch of simple AAC decoder optimizations. Biggest speedup is on ColdFire targets, but ARM targets benefits too. Allows realtime playback of some AAC files on Iriver targets (H1x0, H3x0). Remove support for some rarely used AAC profiles to reduce code size a bit. 2006-09-24T19:00:29+00:00 Magnus Holmgren magnushol@gmail.com 2006-09-24T19:00:29+00:00 3fa5e5f5924306417c05cbc7a7f46a605c670996 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11038 a1c6a512-1295-4272-9138-f99709370657

Changes to make libfaad compile in Rockbox. Also remove compiler warnings, use some IRAM (IRAM usage needs reviewing) and drastically reduce the stack usage 2005-10-31T20:33:27+00:00 Dave Chapman dave@dchapman.com 2005-10-31T20:33:27+00:00 798a4f3533cc63be2b313797bd4be5d53bda8fb9 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7700 a1c6a512-1295-4272-9138-f99709370657
