VPAVGW xmm {k}, xmm, xmm
Synopsis
 _mm_mask_avg_epu16(__m128i src, __mmask8 k, __m128i a, __m128i b);
Description
Average packed unsigned 16-bit integers in "a" and "b", 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 7
	i := j*16
	IF k[j]
		dst[i+15:i] := (a[i+15:i] + b[i+15:i] + 1) >> 1
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI
ENDFOR
dst[MAX:128] := 0
