Codec memory reorganization

2008-10-19T12:35:53+00:00

Based on a patch by Tomasz Malesinski
* Merge Codec buffer and Malloc buffer into one large buffer.
* The new merged buffer is now 1MB on targets with lots of memory.
* Renamed codec_get_memory to codec_get_buffer and made it behave more. 
like plugin_get_buffer.
* Bumped Codec api and min api versions.

Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs.

Vorbis codec: Only try to put the ARM assembler optimised MDCT in IRAM if the target uses IRAM. This fixes the code for gigabeat, but it is kept disabled for gigabeat because the C code is actually slightly faster (~0.5%).

Change oggmalloc.c to use size_t and kill a warning about type-punning. Align the size before checking out-of-mem so no overlap may occur between tmp and alloc.

disable the ARM optimized MDCT for the Gigabeat for now as it creates a data abort

FS #7833: Optimizations to the Vorbis codec:

2007-09-27T21:58:51+00:00

- ARM assembly version of parts of mdct,
- special case for vorbis_book_decodevv_add for 2 channels and even book->dim,
- store the output in vb->pcm if possible, as it is usually in IRAM as
  opposed to v->pcm.
