2011-06-05FS#12146: Fix libcook bugs introduced in r22055 by Sean Bartell.Nils Wallménius
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29973 a1c6a512-1295-4272-9138-f99709370657
2011-06-02FS#12141 by Sean BartellNils Wallménius
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
2011-05-22Submit FS#12115: Use more IRAM in cook codec for several targets. Speeds up ↵Andree Buschmann
PP5022 and MCF5250 by ~3% and S5L87.0x by ~4%. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29913 a1c6a512-1295-4272-9138-f99709370657

2010-07-18FS#11454 Tuning of codec compiler optionsNils Wallménius
Tested with h300 and sansa c200v1 h300 speedups: a52: 2% cook: 9-17% aac: 0.5% vorbis: 0.5% wma: 6-12% c200v1 speedups: alac: 1.5% wma 3-4% wavpack 2% git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27486 a1c6a512-1295-4272-9138-f99709370657
2010-07-15Sync codeclib bitstream code with upstream ffmpeg code. Build ↵Nils Wallménius
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
2010-05-14Set up EMAC mode in cook, fixing whitenois when transitioning from a codec ↵Nils Wallménius
using different emac mode.' git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26016 a1c6a512-1295-4272-9138-f99709370657
2010-05-06Move c/h files implementing/defining standard library stuff into a new libc ↵Thomas Martitz
directory, also standard'ify some parts of the code base (almost entirely #include fixes). This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657
2010-05-06Make open() posix compliant api-wise. A few calls (those with O_CREAT) need ↵Thomas Martitz
the additional optional mode parameter so add it. Impact for the core is almost zero, as open() is a wrapper macro for the real open function which doesn't take the variable parameter. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25844 a1c6a512-1295-4272-9138-f99709370657

2010-02-21Further work on cook codec. Rounding is not needed when using a large fract ↵Andree Buschmann
part in the internal sample representation. Move quantization array to iram. Beautification of mdct post processing. Speed up of 0.2 MHz on PP5022. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24821 a1c6a512-1295-4272-9138-f99709370657
2010-02-21Optimization for cook codec. Rework sample output to be able to use highly ↵Andree Buschmann

2009-12-05Move av_log2 function and asociated table to the codec lib, remove 3 ↵Nils Wallménius
identical implementations, always have LUT in iram (gives a *tiny* speedup on coldfire), make the clz based function return the same value as the non clz based function for 0 input to be safe (slows down flac ~2% on the gigabeat S) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23858 a1c6a512-1295-4272-9138-f99709370657

2009-07-26Approx 10% speedup in cook on files tested: Remove some inner loops in ↵Dave Hooper
favour of memcpy/memset/vect_add calls; remove multiplication from index arithmetic in loops in favour of pointer arithmetic; make use of the MULT31, MULT31_SHIFT15 and CLIP_TO_15 implementations from codelib instead of having their own implementations in cook git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22055 a1c6a512-1295-4272-9138-f99709370657

check for sign outside of the for loop. 3% speedup on PP5024. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21940 a1c6a512-1295-4272-9138-f99709370657
2009-07-17Rearrange the MDCT library lookup tables so that codecs can access them. ↵Michael Giacomelli
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
