2014-07-13libopus: use iram for more constantsNils Wallménius
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
2014-07-13libopus: asm C_MUL for coldfireNils Wallménius
The recent merge of upstream changed the fft to use C_MUL which wasn't implemented in asm for coldfire. Speeds up decoding 64 kbps test file by 2.68 MHz and 128 kbps test file by 2.80 MHz on H300. Change-Id: I8b61fc0f9568d6350431e311a12e44fe4f60f72e
2014-07-13Sync to upstream libopusNils Wallménius
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

2013-08-31Sync opus codec to upstream gitNils Wallménius
Sync opus codec to upstream commit 02fed471a4568852d6618e041c4f2af0d7730ee2 (August 30 2013) This brings in a lot of optimizations but also makes the diff between our codec and the upstream much smaller as most of our optimizations have been upstreamed or supeceded. Speedups across the board for CELT mode files: 64kbps 128kbps H300 9.82MHz 15.48MHz c200 4.86MHz 9.63MHz fuze v1 10.32MHz 15.92MHz For the silk mode test file (16kbps) arm targets get a speedup of about 2MHz while the H300 is 7.8MHz slower, likely because it's now using the pseudostack more rather than the real stack which is in iram. Patches to get around that are upcomming. Change-Id: Ifecf963e461c51ac42e09dac1e91bc4bc3b12fa3
2013-08-23Change CODECFLAGS to a "simply-expanded" var to give the individualNils Wallménius
codec makefiles larger freedom in what they can do to it. Use this in libopus to prepend the libopus searchpaths to CODECFLAGS so that its internal config.h will be picked up before our global one. This avoids having to do a s/config.h/opus_config.h/ when syncing which will be handy soon.

2013-05-18Fix opus craches with large embedded album artNils Wallménius
Use the tlsf malloc and friends instead of the silly codec_malloc to get actually working free and saner realloc that doesn't leak memory. Makes files with moderately sized embedded AA play on targets with large enough codec buffers and files with too large AA are now skipped rather than crashing. Fixes crash when playing example file in FS#12842. Change-Id: I06562955c4d9a95bd90f55738214fba462092b71
2013-01-21ARMv5 optimized complex multiply function for libopus.Michael Giacomelli
Speeds up decoding of 128k opus files by 1.2MHz on AMSv2. Rounding error is 1 bit due to KissFFT using a 15 bit shift instead of a 16 bit shift. Also, change an LDMIA in the armv4 code to LDM as the pointer should not increment.
