* Revert r14786 which resulted in a substantial reduction in accuracy to save ↵Michael Giacomelli2008-06-24
| | | | | | a 7.6KB of RAM. Accuracy should be greatly improved now, and if we want to make that trade off again, I think of better ways to do it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17783 a1c6a512-1295-4272-9138-f99709370657
* Fix for WMAv1 decoding suggested by Rafael Carre. I don't think anyone out ↵Michael Giacomelli2008-06-24
| | | | | | there will ever use V1, but its worth having correct code for its own sake. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17782 a1c6a512-1295-4272-9138-f99709370657

* Resort operands in mul/smull/mla/smlal to use D[] as second multiplication ↵Andree Buschmann2008-06-14
| | | | | | operand. Additionally do not pre-scale D[] for the 64 Bit precision synthesizer. Through this the 64 Bit multiplication is speed up by 1.5MHz without loss of precision. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17719 a1c6a512-1295-4272-9138-f99709370657

* Further changes in mpc buffered seek. Remove magical number and replace it ↵Andree Buschmann2008-06-04
| | | | | | with a better commented #define. Use shift and bit mask instead of division and modulo operations when using the seek buffer. Saves some binary size for the codec. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17686 a1c6a512-1295-4272-9138-f99709370657

* libmad: PP5002 does in fact profit more from -O2 than PP502x, so use it for ↵Jens Arnold2008-06-01

* Compile libmad with -O2 for the Ipods instead of just newer PP targets. ↵Michael Giacomelli2008-06-01

* Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer ↵Andree Buschmann2008-05-22
| | | | | | of 8192 entries is used. The seeking precision is adapted to the length of the file (e.g. 26ms for files <=3.5min and 0.4s for files ~60min). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17604 a1c6a512-1295-4272-9138-f99709370657

* Musepack seek hotfix. Do not dynamically allocate seek buffer but use a ↵Andree Buschmann2008-05-19
| | | | | | buffer of constant size (~28.5min). Files larger than this will still not seek properly. Some additional rework has to be done for the seek buffer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17584 a1c6a512-1295-4272-9138-f99709370657

* Musepack performance optimization for PP5022/PP5024/MCF5250 targets. Use ↵Andree Buschmann2008-05-14
| | | | | | IRAM for internal sample buffers and lookup tables. Speeds up decoding by ~7% on PP5022/PP5024 (Sansa: c200, e200 + iPod mini2G, nano, video) and by ~27% on MCF5250 (iaudio m5, x5). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17507 a1c6a512-1295-4272-9138-f99709370657

* Some changes for musepack: Disable SV4-SV6 support (I guess I am the only ↵Andree Buschmann2008-05-10
| | | | | | one who oned such). Remove tabs, perform some minor code beautification and add ICONST_ATTR to some requantization constants. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17438 a1c6a512-1295-4272-9138-f99709370657

* This table is probably 128 entries long beginning with -60. Greatly improves ↵Michael Giacomelli2008-04-18

NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16981 a1c6a512-1295-4272-9138-f99709370657
