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
optimized dsp routines. Moved some functions to iram. Speeds up codec by 1.3 MHz on PP5022. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24815 a1c6a512-1295-4272-9138-f99709370657

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
2009-08-15Move bitstream.[ch] to codecs/lib/ffmpeg_bitstream.[ch] to avoid duplicate ↵Mohamed Tarek

2009-08-15remove duplicates of bswap.h from libwma, libcook and libatrac. Create ↵Mohamed Tarek
codecs/lib/ffmpeg_bswap.h and use it instead. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22328 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

2009-05-22Move the code segment that corrects the value of (number of packets) to Mohamed Tarek
the parser. This is strictly parser-related and main.c shouldn't have to deal with it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21043 a1c6a512-1295-4272-9138-f99709370657
2009-05-22Modify the test program to read audio frames from a memory buffer rather Mohamed Tarek
than a file descriptor, to make the decoding process as much similar as to how it should be in rockbox. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21042 a1c6a512-1295-4272-9138-f99709370657

2009-05-12-Remove all dynamic allocations, hence remove cook_decode_close() which was ↵Mohamed Tarek

RealAudio support in Rockbox. This is a self-contained Cook decoder using the original ffmpeg (still floating point) decoder and a new RM parser started by me in 2008 and continued by MT over the past few months. This is the equivalent of libcook.patch1 from FS#10182, but with further cleaning by both MT and me to minimise the differences to the original ffmpeg files. See README.rockbox for more details. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20883 a1c6a512-1295-4272-9138-f99709370657
