Synopsis
_mm512_mask_cvtepu8_epi32(__m512i src, __mmask16 k, __m128i a);
Description
Zero extend packed unsigned 8-bit integers in "a" to packed 32-bit integers, 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 15
i := 32*j
l := 8*j
IF k[j]
dst[i+31:i] := ZeroExtend32(a[l+7:l])
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
