VPMULUDQ xmm {k}, xmm, xmm
Synopsis
 _mm_mask_mul_epu32(__m128i src, __mmask8 k, __m128i a, __m128i b);
Description
Multiply the low unsigned 32-bit integers from each packed 64-bit element in "a" and "b", and store the unsigned 64-bit results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 1
	i := j*64
	IF k[j]
		dst[i+63:i] := a[i+31:i] * b[i+31:i]
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
dst[MAX:128] := 0
