Explanation
1. This instruction multiplies the signed binary value in S
D.
2. Only the instruction D* can use the 32-bit counter.
3. Multiplying 16-bit binary values:
The product is a 32-bit value, and is stored in the register (D+1, D), which is composed of 32 bits. When the sign
bit b31 is 0, the product is a positive value. When the sign bit b31 is 1, the product is a negative value.
