3. Calculate the CPU time to execute a program containing one

3. Calculate the CPU time to execute a program containing one million machine instructions, when the average CPI of the CPU is 2.5 and CPU clock frequency is 2GHz. [15pts] 4. Let us overclock the machine given in problem 3 by increasing the CPU clock frequency from 2GHz to 2.5GHz. Calculate the CPU time of the overclocked machine running the same program containing one million instructions. How much faster (i.e., performance ratio) is the overclocked machine than the original machine? (15pts]
