2019-07-08Avoid processing LPC coeffs beyond the given order in NEON optimizationsFelicia Lim
2018-07-22Silence compiler warningsMark Harris
clang -Wcast-align warnings with ambisonics enabled clang -Wnull-pointer-arithmetic warnings in test_opus_api.c gcc -Wimplicit-fallthrough warnings on arm msvc warning C4244 in celt_encoder.c with fixed point
2017-06-03Don't use MAY_HAVE_NEON in arm_silk_map.c.Jonathan Lennox
It's unnecessary, and isn't defined correctly on floating-point. This makes us correctly use Neon functions (in floating-point mode) on platforms where Neon is detected by RTCD. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
2017-05-17Optimize silk_biquad_alt_stride2() for ARM NEONLinfeng Zhang
The optimization is bit exact with C function. Change-Id: Ifb8f04b19f2d576e79ce5dcfa7e0fc374d71d6c8 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-04-14Optimize silk_warped_autocorrelation_FIX() for ARM NEONLinfeng Zhang
The optimization is bit exact with C function. This optimization speeds up fixed-point SILK encoder on NEON about 5% to 8%. (Tested on Acer Chromebook, ARMv7 Processor rev 3 (v7l).) Change-Id: I582f6f3585b7946149e16a2ad3084ebc0ae79a4f Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-02-15Optimize silk_LPC_inverse_pred_gain() for ARM NEONLinfeng Zhang
The optimization is bit exact with C function. Change-Id: Ib3bdc26a5a4ebe02e7f24be85104e8e9a2a9a738 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>

2017-01-31Optimize silk_NSQ_del_dec() for ARM NEONLinfeng Zhang
The optimization is bit exact with C function. This optimization speeds up SILK encoder on NEON as following. Fixed-point: Complexity 0-5: 0% Complexity 6-7: 6% Complexity 8-9: 10% Complexity 10: 8% Got similar results on floating-point. Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
2017-01-26Avoids undefined behaviour in ARM-optimized codeJean-Marc Valin
Casting to unsigned to avoid shifting negative values left.

2013-10-28Replace "inline" with OPUS_INLINE.Gregory Maxwell
Newer versions of MSVC are unhappy with the strategy of the build environment redefining "inline" (even though they don't support the actual keyword). Instead we define OPUS_INLINE to the right thing in opus_defines.h. This is the same approach we use for restrict.

2011-03-08Support for glitchles mode switchingJean-Marc Valin
Uses a 5ms redundant CELT frame embedded into the SILK or hybrid packet to handle the switching. It's still possible to use the PLC-based method when no redundant packet is included.
