Instruction
PMULLD xmm, xmm
Synopsis
_mm_mullo_epi32(__m128i a, __m128i b);
Description
Multiply the packed 32-bit integers in "a" and "b", producing intermediate 64-bit integers, and store the low 32 bits of the intermediate integers in "dst".
Operation
FOR j := 0 to 3
i := j*32
tmp[63:0] := a[i+31:i] * b[i+31:i]
dst[i+31:i] := tmp[31:0]
