Instruction
VPSRLD xmm {z}, xmm, xmm
Synopsis
_mm_maskz_srl_epi32(__mmask8 k, __m128i 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 zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
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] := 0
FI
ENDFOR
dst[MAX:128] := 0
