Instruction
PMULHW xmm, xmm
Synopsis
 _mm_mulhi_epi16(__m128i a, __m128i b);
Description
Multiply the packed signed 16-bit integers in "a" and "b", producing intermediate 32-bit integers, and store the high 16 bits of the intermediate integers in "dst".
Operation
FOR j := 0 to 7
	i := j*16
	tmp[31:0] := SignExtend32(a[i+15:i]) * SignExtend32(b[i+15:i])
	dst[i+15:i] := tmp[31:16]
