Consider three different processors P1, P2, and P3 executing the same instruction set. P1 has a 5.1 GHz clock rate and a CPl of 0.33. P2 has a 4.9 GHz clock rate and a CPI of 1.94. P3 has a 3.9 GHz clock rate and a CPI of 1.96. (a) How many instructions per second can each processor execute? (b) If the processors each execute a program in 60 seconds, find the number of cycles and the number of instructions of the program. (c) Suppose we implement an architectural optimization on P3 which reduces the CPU time by 14% but leads to an increase of 8% in the CPI. What is the new clock rate?
