(S1+1, S1)
The multiplied result is stored in the 64-bit area.
When processing 32-bit data, the higher 16-bit areas (S1+1, S2+1) are automatically determined once the
lower 16-bit areas (S1, S2) are specified.
The areas (D+3, D+2, D+1) other than the lowest 16-bit area (D) are automatically determined once the
lowest 16-bit area is specified.
