Synopsis
_mm512_slli_epi16(__m512i a, unsigned int imm8);
Description
Shift packed 16-bit integers in "a" left by "imm8" while shifting in zeros, and store the results in "dst".
Operation
FOR j := 0 to 31
i := j*16
IF imm8[7:0] > 15
dst[i+15:i] := 0
ELSE
dst[i+15:i] := ZeroExtend16(a[i+15:i] << imm8[7:0])
FI
ENDFOR
dst[MAX:512] := 0
