Instruction
VPMOVDB xmm {z}, zmm
Synopsis
 _mm512_maskz_cvtepi32_epi8(__mmask16 k, __m512i a);
Description
Convert packed 32-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 15
	i := 32*j
	l := 8*j
	IF k[j]
		dst[l+7:l] := Truncate8(a[i+31:i])
	ELSE
		dst[l+7:l] := 0
	FI
ENDFOR
dst[MAX:128] := 0
