Consider two different implementations, P1 and P2, of the same instruction set. There are three classes of instructions (A, B and C) in the instruction set. P1 has a clock rate of 3.0 GHz and P2 has a clock rate of 2.55 GHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Instruction Class Machine P1 - Machine P2 - Cycles/Instruction Cycles/Instruction Frequency Class Class A 2 1 50% B 2 2 35% 2 3 15% Calculate the average CPI for machine P1. Calculate the average MIPS rating for machine P1. What is the relative performance (P1/P2)? Which processor has the higher performance
