Synopsis
_mm512_maskz_avg_epu16(__mmask32 k, __m512i a, __m512i b);
Description
Average packed unsigned 16-bit integers in "a" and "b", 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 31
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] := 0
FI
ENDFOR
dst[MAX:512] := 0
