Instruction
VPMINUB xmm {k}, xmm, xmm
Synopsis
_mm_mask_min_epu8(__m128i src, __mmask16 k, __m128i a, __m128i b);
Description
Compare packed unsigned 8-bit integers in "a" and "b", and store packed minimum values 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] := MIN(a[i+7:i], b[i+7:i])
ELSE
dst[i+7:i] := src[i+7:i]
FI
ENDFOR
dst[MAX:128] := 0
