Question 1: Consider two computers, P1 and P2. Computer P1 has a clock rate of 2 Ghz and Computer P2 has a clock rate of 800 Mhz. There are three classes of instructions (A, B and C) in the instruction set. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Instruction category Computer cycles/instruction class 3 2 4 P1- Computer P2- frequency cycles/instruction class 1 55% 3 20% 2 35% A B a) Calculate the average CPI for each machine P1 and P2 b) Find the clock cycles for each machine P1 and P2 c) Consider One alternative to time is MIPS (million instructions per second). For a given program, MIPS is simply Instruction count MIPS = Execution time X 106 Calculate the average MIPS rating for each computer A and B
