In this section on performance estimation on page 168 it was arbitrarily assumed that the minimum clock period of the 2-bus design would be 1.1 times the clock period of the 1-bus design. Given the delays in exercise 4.11, revisit this problem.

a. Calculate the minimum clock period for the 1-bus and 2-bus designs, assuming a 25% increase in clock periods as a safety factor.

b. Using the clock periods you calculated, compute the speedup to be expected for the 2-bus design.
