Draft: Optimize NSQ_del_dec() for AVX2 (!1) · Merge requests · Victor Ding / Opus

Victor Ding requested to merge NSQ_del_dec into master Aug 07, 2021

The optimization is bit-exact with C function.

This optimization speeds up SILK encoder (floating point) as following:

AMD Zen: Complexity 0-5 : 0% Complexity 6-7 : 3 - 7% Complexity 8-10: 8 - 15%

Intel Skylake: Complexity 0-5 : 0% Complexity 6-7 : 14 - 18% Complexity 8-10: 17 - 22%
