1.11 Exercises CPI Class A CPI Class B CPI Class C cPI Class D CPI Class E P1 P2 P1 P2 1.6.4 [5] Assume that peak performance is defined as the fastest rate that a computer can execute any instruction sequence. What are the peak performances of P1 and P2 expressed in instructions per second? 1.6.5 [5] If the number of instructions executed in a certain program is di- vided equally among the five classes of instructions except for class A, which occurs twice as often as each of the others, how much faster is P2 than Pi? 1.4> At what frequency does PI have the same performance of P2 for 1.6.6 [5]
