1. Consider three processors P1,P2 and P3 executing the same instruction set. (Assume the number of instructions in the instruction set are n; for the same processor, each instruction has the same CPI). P1 has a 4GHz clock rate and a CPI of 2.5. P2 has a 2.5GHz clock rate and a CPI of 2.0. P3 has a 5.0GHz clock rate and has a CPI of 1.2. (12) a. Calculate the CPU time to execute the same instruction set for P1, P2, P3 respectively b. Calculate the number of instructions executed per second for P1,P2,P3 respectively. Note: please give the computation processes and the computation results, otherwise you will lose the credits
