2012-04-25Add codecs to librbcodec.Sean Bartell1-12/+0

2012-01-21Move supprt-arm.S to separate library.Thomas Martitz1-4/+0
Core, codecs and plugins link it separately so this gets rid of SOURCES trickery. Don't build it for hosted targets. Change-Id: If15ef90e93cd218a4352ae8e89eea95d3122452f

Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note: * The old MDCT has been removed. * Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs. * I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29945 a1c6a512-1295-4272-9138-f99709370657

it as separate library. It's used by both, plugins and codecs, and sh/hwcodec doesn't compile codecs so it doesn't fit into sources. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27869 a1c6a512-1295-4272-9138-f99709370657
2010-07-15Sync codeclib bitstream code with upstream ffmpeg code. Build ↵Nils Wallménius1-0/+1
ffmpeg_bitstream.c as a part of the codec lib. Use this codeclib implementation in libffmpegFLAC. Implement adapted version of the unaligned longword reading optimization for coldfire from the libwma version of this code. Speeds up cook decoding by 2-3% on h300 and flac by 25% on h300, also speeds up flac decoding by 2% on c200 (decoding speed of cook on c200 is unchanged). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27430 a1c6a512-1295-4272-9138-f99709370657
2010-06-21Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with ↵Thomas Martitz1-1/+1
#if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR). The new define is to (de-)select code to compile on hosted platforms generally. Should be no functional change to targets or the simulator. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27019 a1c6a512-1295-4272-9138-f99709370657

2010-01-28Improvements to specialized dividers for APE codec:Andrew Mahone1-3/+1
* Use Newton-Raphson divider on ARMv5e and ARMv6, about 7% speedup on Gigabeat S. * On ARMv4 targets using IRAM, remove insane filter buffer from IRAM, fill available IRAM with LUT of reciprocals for small divisors - speedup varies according to target and available IRAM, APE normal sample is approx. 109% RT on e200. * Rename apps/codecs/lib/udiv32_armv4.S to apps/codecs/lib/udiv32_arm.S, which includes dividers for all ARM targets specialized for APE. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24354 a1c6a512-1295-4272-9138-f99709370657
2009-07-17Rearrange the MDCT library lookup tables so that codecs can access them. ↵Michael Giacomelli1-0/+1
Access them in cook. Remove old cook trig tables. Replace old 32x16 bit fixed point multiply code with faster ASM ARM/Coldfire versions using full 32 bit precision. Improves performance signficantly on PP5024 (~200% realtime for a 64k file) while saving a lot of memory and improving accuracy. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21939 a1c6a512-1295-4272-9138-f99709370657

2009-03-08Add setjmp/longjmp for ARM and ColdFire to the codec lib, and use it in the ↵Magnus Holmgren1-0/+5
Vorbis codec to better handle out of memory conditions (to exit rather than crash; the AAC codec could use it too). setjmp/longjmp comes from newlib 1.17.0 with a few minor changes (combine parts of some files, remove support for some architectures, change some ifdef's). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20235 a1c6a512-1295-4272-9138-f99709370657

the ARMv5(+) version from libgcc), in IRAM on PP for better performance on PP5002, and put into the codeclib for possible reuse. APE -c1000 is now usable on both PP502x and PP5002 (~138% realtime, they're on par now). Gigabeat F/X should also see an APE speedup. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19009 a1c6a512-1295-4272-9138-f99709370657
2008-09-04Combine the Vorbis, WMA and AAC IMDCT functions and put them into the ↵Michael Giacomelli1-0/+7
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

lib/codeclib.[ch] and lib/xxx2wav.[ch] into just codeclib.[ch]. Deleted much of the unused code in the xxx2wav portion. All codecs should now only include codeclib.h, and whatever codec specific headers are needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7626 a1c6a512-1295-4272-9138-f99709370657
