Question: 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

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

At what frequency does P1 have the same performance of P2 for the instruction mix given in 1.6.5?

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
