We have the following statistics for two processors P1 and P2. The two processors have the same classes of instructions. Given a program generates code with 2 billion Class A instructions, 1 billion Class B instructions, and 1 billion Class C instructions. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Processor P1, Clock Rate = 200 Processer P2, Clock Rate = 250 MHz MHz Instruction Instruction CPI Frequency CPI Frequency class class А 20 % А 3 30 % 40 % В 3 30 % C 3 40 % C 4 40 % a. Calculate the average CPI for the two processors. b. Which machine is faster?
