Synopsis
_mm256_mask_adds_epi8(__m256i src, __mmask32 k, __m256i a, __m256i b);
Description
Add packed signed 8-bit integers in "a" and "b" using saturation, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
i := j*8
IF k[j]
dst[i+7:i] := Saturate8( a[i+7:i] + b[i+7:i] )
ELSE
dst[i+7:i] := src[i+7:i]
FI
ENDFOR
dst[MAX:256] := 0
