NV12ToARGB in 1 step AVX2 #403

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Various YUV to ARGB are implemented as
1. AVX2
2. SSSE3
3. Multi-step SSSE3 called by C
4. C

On Neon all YUV formats are supported natively, plus several RGB outputs.
To achieve this on Intel
1. write macros to do READ for any YUV format
2. write C wrappers for multistep AVX2
3. implement YUV conversion via matrix to allow SSSE3/AVX2 instead of C for 
more formats

These functions have C wrappers for SSSE3

findstr void.*SSE row_common.cc
void I422ToRGB565Row_SSSE3(const uint8* src_y,
void I422ToARGB1555Row_SSSE3(const uint8* src_y,
void I422ToARGB4444Row_SSSE3(const uint8* src_y,
void NV12ToRGB565Row_SSSE3(const uint8* src_y,
void NV21ToRGB565Row_SSSE3(const uint8* src_y,
void YUY2ToARGBRow_SSSE3(const uint8* src_yuy2,
void UYVYToARGBRow_SSSE3(const uint8* src_uyvy,

They are candidates for
1. direct conversions - use macros to read and store.
2. AVX2 wrappers of similar nature.  port the functions they call to AVX2.

Some are 2 or 3 steps.  NV12ToARGB is 1 step AVX2.
