VPSUBUSW xmm {k}, xmm, xmm
Synopsis
_mm_mask_subs_epu16(__m128i src, __mmask8 k, __m128i a, __m128i b);
Description
Subtract packed unsigned 16-bit integers in "b" from packed unsigned 16-bit integers in "a" 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 7
i := j*16
IF k[j]
dst[i+15:i] := SaturateU16(a[i+15:i] - b[i+15:i])
ELSE
dst[i+15:i] := src[i+15:i]
FI
ENDFOR
dst[MAX:128] := 0
