Consider three different processor P1, P2, and P3 which are executing on the same instruction set with the following clock rates and CPls 2. Processor | Clock Rate CPI 3 GHz 2.5 GHz 4 GHz 1.5 P1 P2 P3 1.0 2.2 Table:2 Table 2 processor with clock rate and CPI, here CPI denotes the clock cycles per instruction a) Calculate the performance of each processor. b) It the processor each execute a program in 10s, find the number of cycles and number of instructions. c)) we are trying to reduce the execution time by 30%, but this lead to an increases of 20% in the CPI. what clock rate should we have to get this time reduction. d) Calculate the clock rate to get the time reduction by using the following formula
