VPSRAW zmm {k}, zmm, xmm
Synopsis
 _mm512_mask_sra_epi16(__m512i src, __mmask32 k, __m512i a, __m128i count);
Description
Shift packed 16-bit integers in "a" right by "count" while shifting in sign bits, 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 31
	i := j*16
	IF k[j]
		IF count[63:0] > 15
			dst[i+15:i] := (a[i+15] ? 0xFFFF : 0x0)
		ELSE
			dst[i+15:i] := SignExtend16(a[i+15:i] >> count[63:0])
		FI
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI
ENDFOR
dst[MAX:512] := 0
