Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on 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. 2010-11-10T18:29:29+00:00 Michael Giacomelli giac2000@hotmail.com 2010-11-10T18:29:29+00:00 f51189fa4d16c138c951775a237326b807fdda89 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28549 a1c6a512-1295-4272-9138-f99709370657

Sync codeclib bitstream code with upstream ffmpeg code. Build 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). 2010-07-15T16:19:17+00:00 Nils Wallménius nils@rockbox.org 2010-07-15T16:19:17+00:00 a87c61854ef614b258ca7d4d0b40db017884e63e git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27430 a1c6a512-1295-4272-9138-f99709370657

Submit interim version of FS#10565. Performance optimization of atrac3 decoder for ARM. Introduce ASM routines for multiplications and two synthesis loops, refactured parts of synthesis and windowing. Speeds up decoding by a factor of 2.4 on PP502x. 2009-08-29T19:44:27+00:00 Andree Buschmann AndreeBuschmann@t-online.de 2009-08-29T19:44:27+00:00 f4774bf5bf8fff2b45a6cee8e0b064b560b45809 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22548 a1c6a512-1295-4272-9138-f99709370657

Make those functions actually inline.
