DVP-ES3 Series Programming Manual Symbol S 1 ： Multiplicand S 2 ： Multiplier D ： Product _6 Explanation 1. This instruction multiplies the signed binary value in S 1 by the signed binary value in S 2 , and stores the product in D . 2. Only the MUL32 instruction can use an HC device. 3. 16-bit binary multiplication: S 1 2 D S b15..............b0 * = b15..............b0 b15..............b0 Bit 15 is a sign bit. Bit 15 is a sign bit. Bit 15 is a sign bit. The product is a 16-bit value stored in D which is a 16-bit register. If b15 in D is 0, the product stored in D is a positive value. If b15 in D is 1, the product stored in D is a negative value.
