Instruction
VPADDUSB xmm {k}, xmm, xmm
Synopsis
_mm_mask_adds_epu8(__m128i src, __mmask16 k, __m128i a, __m128i b);
Description
Add packed unsigned 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 15
i := j*8
IF k[j]
dst[i+7:i] := SaturateU8( a[i+7:i] + b[i+7:i] )
ELSE
dst[i+7:i] := src[i+7:i]
FI
ENDFOR
dst[MAX:128] := 0
