Instruction
VPSRLD zmm {z}, zmm, imm8
Synopsis
_mm512_maskz_srli_epi32(__mmask16 k, __m512i a, unsigned int imm8);
Description
Shift packed 32-bit integers in "a" right by "imm8" 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 15
i := j*32
IF k[j]
IF imm8[7:0] > 31
dst[i+31:i] := 0
ELSE
dst[i+31:i] := ZeroExtend32(a[i+31:i] >> imm8[7:0])
FI
ELSE
dst[i+31:i] := 0
FI
ENDFOR
dst[MAX:512] := 0
