Instruction
VPMOVSWB xmm {k}, xmm
Synopsis
_mm_mask_cvtsepi16_epi8(__m128i src, __mmask8 k, __m128i a);
Description
Convert packed signed 16-bit integers in "a" to packed 8-bit integers with signed 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 := 16*j
l := 8*j
IF k[j]
dst[l+7:l] := Saturate8(a[i+15:i])
ELSE
dst[l+7:l] := src[l+7:l]
FI
ENDFOR
dst[MAX:64] := 0
