Synopsis
_mm512_maskz_cvtepi16_epi8(__mmask32 k, __m512i a);
Description
Convert packed 16-bit integers in "a" to packed 8-bit integers with truncation, 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 := 16*j
l := 8*j
IF k[j]
dst[l+7:l] := Truncate8(a[i+15:i])
ELSE
dst[l+7:l] := 0
FI
ENDFOR
dst[MAX:256] := 0
