VPMOVZXBW ymm {z}, xmm
Synopsis
_mm256_maskz_cvtepu8_epi16(__mmask16 k, __m128i a);
Description
Zero extend packed unsigned 8-bit integers in "a" to packed 16-bit integers, 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 15
i := j*8
l := j*16
IF k[j]
dst[l+15:l] := ZeroExtend16(a[i+7:i])
ELSE
dst[l+15:l] := 0
FI
ENDFOR
dst[MAX:256] := 0
