(Sequential Multiplier)The multiplier of Section 10.5 computes partial products by looking at one bit of the multiplier during each clock cycle. Construct a sequential multiplier that operates on two bits of the multiplier in every clock cycle. You will now need to accumulate 0, 1, 2, or 3 times the multiplicand. Add circuitry around the accumulator to implement these four functions. Modify the shift registers to shift two bits at a time instead of one. Now your multiplier will compute a result in only four clock cycles? But will the logic you added have an effect on the length of a clock period? Do you expect the cost (more logic) to outweigh the benefits (fewer clock cycles)?
