libtremor: port over ffmpeg's windowing code

2011-09-22T11:47:51+00:00

Use the windowing approach from ffmpeg in tremor, does the mdct doubling, windowing and overlap add in one go.
Also uses less memory so all the processing buffers fit in iram on targets with small iram for the common blocksizes (256/2048) now.

Speeds up decoding of vorbis files by 3MHz for 256/2048 and 20MHz for 512/4096 files on h300.
Speeds up decoding of vorbis files by 3MHz for 256/2048 and 4.5MHz for 512/4096 on the beast.
Speeds up decoding of vorbis files by 0.3MHz for 256/2048 and 1MHz for 512/4096 on c200v1.

libtremor: Implement a memory configuration for targets that don't use separate iram for codecs.

2011-06-06T13:27:12+00:00

Such targets would previously default to using the configuration for targets with small iram which uses an extra memcpy per block.
This saves 2MHz decoding a 128kbps vorbis file on the Gigabeat S and saves a bit of codec buffer.
Patch from FS#11268, also replaces patch from FS#12147.

Safe part of FS#11268, saving some codec buffer space for targets that don't use separate iram.

Delete old unused macro.

Clean up a leftover preprocessor symbol and improve the workaround for the 'arm-elf and static functions in iram' quirk so it doesn't affect builds with eabi toolchain (only affects nano2g).

Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes).

2010-05-06T21:04:40+00:00

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

Use larger IRAM for M5/X5 in vorbis.

Make the codecs use more IRAM on S5L870x, as we have plenty of it.

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23594 a1c6a512-1295-4272-9138-f99709370657

Add STATICIRAM_NOT_MDCT as a workaround for the gcc bug where static functions are not long called. This is currently only an issue on the Nano2G (S5L8701 CPU) which is the only ARM target with enough IRAM for these functions. Also add multiple-inclusion protection for config-tremor.h. All plugins and codecs now compile cleanly for the Nano2G.
