4. [Multiplication] Calculate the time necessary to perform a multiply using the approach given in P&H Figures 3.3 (above) and 3.4 (below) if an integer is 8 bits wide and each step of the operation takes 4 time units. Assume that in step la an addition is always performed either the multiplicand will be added, or a zero will be. Also assume that the registers have already been initialized. If this is being done in hardware, the shifts of the multiplicand and multiplier can be done simultaneously. If this is being done in software, they will have to be done one after the other. Solve for each case. P&H Figure 3.4: Start Multiplier = 1 Multiplier = 0 1. Test Multipliero 1a. Add multiplicand to product and place the result in Product register 2. Shift the Multiplicand register left 1 bit 3. Shift the Multiplier register right 1 bit No:
