Synopsis
_mm512_mask_mulhi_epi32(__m512i src, __mmask16 k, __m512i a, __m512i b);
Description
Performs element-by-element multiplication between packed 32-bit integer elements in "a" and "b" and stores the high 32 bits of each result into "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
i := j*32
IF k[j]
dst[i+31:i] := (a[i+31:i] * b[i+31:i]) >> 32
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
