Instruction
VPMULLW zmm, zmm, zmm
Synopsis
_mm512_mullo_epi16(__m512i a, __m512i b);
Description
Multiply the packed 16-bit integers in "a" and "b", producing intermediate 32-bit integers, and store the low 16 bits of the intermediate integers in "dst".
Operation
FOR j := 0 to 31
i := j*16
tmp[31:0] := SignExtend32(a[i+15:i]) * SignExtend32(b[i+15:i])
dst[i+15:i] := tmp[15:0]
ENDFOR
dst[MAX:512] := 0
