* FS#12117: Use more IRAM for atrac3. Speeds up decoding from 1-2% (PP5022, ↵Andree Buschmann2011-05-16

* Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on ↵Michael Giacomelli2010-11-10
| | | | | | packed multiply instructions. Additionally, improves scheduling on arm9 and arm11 and forces cache alignment of buffers on all targets. Accuracy is slightly reduced, but still greater then 16 bit. Clip+ CPU clock required for LP2 files decreases by 13MHz and ARM11 by 18MHz. No performance or accuracy changes on armv4 or non-arm. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28549 a1c6a512-1295-4272-9138-f99709370657
* Sync codeclib bitstream code with upstream ffmpeg code. Build ↵Nils Wallménius2010-07-15
| | | | | | 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

Through this several buffers and functions as well as copy loops could be removed. Furthermore add some ASM for coldfire and place some additional data in IRAM on PP5022/24 and X5/M5. Speedup on ARM: +3%, speedup on Coldfire: +639%. Both ARM and Coldfire can decode in realtime now. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22561 a1c6a512-1295-4272-9138-f99709370657
