RGB565 avx2 #421

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
RGB565ToARGB is a common conversion for Android; Optimize it for AVX2.

Current speed for SSE2 on Sandy Bridge is 0.3 ms/frame for 720p:

set LIBYUV_WIDTH=1280
set LIBYUV_HEIGHT=720
set LIBYUV_REPEAT=999
set LIBYUV_FLAGS=-1
out\release\libyuv_unittest --gtest_filter=*RGB565ToARGB*

RGB565ToARGB_Unaligned (382 ms)
RGB565ToARGB_Any (361 ms)
RGB565ToARGB_Invert (343 ms)
RGB565ToARGB_Opt (300 ms)
RGB565ToARGB_Random (60 ms)
