      AVX2 SubPixel AVG Variance Optimization · ea149096
      levytamar82 authored
      Optimizing 2 functions to process 32 elements in parallel instead of 16:
      1. vp9_sub_pixel_avg_variance64x64
      2. vp9_sub_pixel_avg_variance32x32
      both of those function were calling vp9_sub_pixel_avg_variance16xh_ssse3
      instead of calling that function, it calls vp9_sub_pixel_avg_variance32xh_avx2
      that is written in avx2 and process 32 elements in parallel.
      This Optimization gave 80% function level gain and 2% user level gain
