Consider two different implementations, P1 and P2, of the same instruction set. There are five classes of instructions (A, B, C, D, and E) in the instruction set. P1 has a clock rate of 4 GHz, and P2 has a clock rate of 6 GHz. The average number of cycles for each instruction class for P1 and P2 are listed in the following table. a. b. P1 P2 P1 P2 CPI Class A CPI Class B CPI Class C CPI Class D CPI Class E 1 3 1 2 2 3 2 2 3 3 3 2 4 5 4 2

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?

a. b. P1 P2 P1 P2 CPI Class A CPI Class B CPI Class C CPI Class D CPI Class E 1 3 1 2 2 3 2 2 3 3 3 2 4 5 4 2 5 5 5 6
