* libopus: use iram for more constantsNils Wallménius2014-07-13
| | | | | | | | Speeds up decoding of the 64 kbps test file by 2.59 MHz and the 128 kbps test file by 4.31 MHz on H300 (cf). Decoding the same files on c200 is sped up by 0.33 MHz and 0.55 MHz respectively. Change-Id: I0f9f9ef6a7293581cf45e3201b33c65504c95c81
* Sync to upstream libopusNils Wallménius2014-07-13
| | | | | | | | | | | | | | | | | | | | | | Sync to commit bb4b6885a139644cf3ac14e7deda9f633ec2d93c This brings in a bunch of optimizations to decode speed and memory usage. Allocations are switched from using the pseudostack to using the real stack. Enabled hacks to reduce stack usage. This should fix crashes on sansa clip, although some files will not play due to failing allocations in the codec buffer. Speeds up decoding of the following test files: H300 (cf) C200 (arm7tdmi) ipod classic (arm9e) 16 kbps (silk) 14.28 MHz 4.00 MHz 2.61 MHz 64 kbps (celt) 4.09 MHz 8.08 MHz 6.24 MHz 128 kbps (celt) 1.93 MHz 8.83 MHz 6.53 MHz Change-Id: I851733a8a5824b61feb363a173091bc7e6629b58
* opus: put some const tables and structs in iramNils Wallménius2012-09-25
| | | | | | | Speeds up decoding of a 64kbps test file by 20MHz on h300 (cf) and 1MHz on c200 (pp) Change-Id: Ia2adc0a3ad86abce8f948062eb53a8ac14c2cdf2
* Initial opus codec supportFrederik M J Vestre2012-09-20
Synchronised with opus repo on github (https://github.com/freqmod/rockbox-opus) Status: * Seeking ported from speex, but fails on some cases (e.g. seek to granule 0) * ReplayGain parsing needs to be reworked, we do vorbis-style replaygain now. http://wiki.xiph.org/OggOpus#Comment_Header explicitly forbids these in favour of R128_TRACK_GAIN tag. * No optimisation yet, source files still nearly identical to opus upstream * Multi-stream opus files may not be parsed correctly Change-Id: Ia66f1027dc1d288083e3c57b2816700078376f9a Reviewed-on: http://gerrit.rockbox.org/300 Reviewed-by: Bertrik Sikken <bertrik@sikken.nl> Tested-by: Bertrik Sikken <bertrik@sikken.nl>
