VPSRLD zmm {k}, zmm, xmm
Synopsis
_mm512_mask_srl_epi32(__m512i src, __mmask16 k, __m512i a, __m128i count);
Description
Shift packed 32-bit integers in "a" right by "count" while shifting in zeros, 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 15
i := j*32
IF k[j]
IF count[63:0] > 31
dst[i+31:i] := 0
ELSE
dst[i+31:i] := ZeroExtend32(a[i+31:i] >> count[63:0])
FI
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
