Instruction
VPMOVDB xmm {z}, ymm
Synopsis
_mm256_maskz_cvtepi32_epi8(__mmask8 k, __m256i a);
Description
Convert packed 32-bit integers in "a" to packed 8-bit integers with truncation, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := 32*j
l := 8*j
IF k[j]
dst[l+7:l] := Truncate8(a[i+31:i])
ELSE
dst[l+7:l] := 0
FI
ENDFOR
dst[MAX:64] := 0
