* Avoid processing LPC coeffs beyond the given order in NEON optimizationsFelicia Lim2019-07-081-7/+15

* Silence compiler warningsMark Harris2018-07-211-5/+5
| | | | | | | 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
* Don't use MAY_HAVE_NEON in arm_silk_map.c.Jonathan Lennox2017-06-021-16/+16
| | | | | | | | | 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>
* Optimize silk_biquad_alt_stride2() for ARM NEONLinfeng Zhang2017-05-173-0/+238
| | | | | | | | The optimization is bit exact with C function. Change-Id: Ifb8f04b19f2d576e79ce5dcfa7e0fc374d71d6c8 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>
* Optimize silk_warped_autocorrelation_FIX() for ARM NEONLinfeng Zhang2017-04-131-0/+19
| | | | | | | | | | | 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>
* Optimize silk_LPC_inverse_pred_gain() for ARM NEONLinfeng Zhang2017-02-143-0/+348
| | | | | | | | The optimization is bit exact with C function. Change-Id: Ib3bdc26a5a4ebe02e7f24be85104e8e9a2a9a738 Signed-off-by: Jean-Marc Valin <jmvalin@jmvalin.ca>

* Optimize silk_NSQ_del_dec() for ARM NEONLinfeng Zhang2017-01-303-0/+1248
| | | | | | | | | | | | | | | | 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>
* Avoids undefined behaviour in ARM-optimized codeJean-Marc Valin2017-01-253-20/+35
| | | | Casting to unsigned to avoid shifting negative values left.

* Replace "inline" with OPUS_INLINE.Gregory Maxwell2013-10-284-19/+19
| | | | | | | | | 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.
* Move ARM asm into its own directories.Timothy B. Terriberry2013-05-214-0/+424

* Support for glitchles mode switchingJean-Marc Valin2011-03-071-5/+5
| | | | | | 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.
