Synopsis
_mm512_mulhi_epu16(__m512i a, __m512i b);
Description
Multiply the packed unsigned 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 31
i := j*16
tmp[31:0] := a[i+15:i] * b[i+15:i]
dst[i+15:i] := tmp[31:16]
ENDFOR
dst[MAX:512] := 0
