Assume a program requires the execution of 50*106 FP instructions, 110*106 INT instructions, 80*106 L/S instruction and 16*106 branch instructions. The CPI for each type of instruction is 1, 1, 4, and 2, respectively. Assume the processor has a 2GHZ clock rate. a. What is the CPU time of this program? b. Assuming we want the program to run 10% faster by improving only the FP CPI value, what would be the value of the new CPIFP' to achieve this goal? c. By how much must we improve the CPI of FP instructions if we want the program to run twice as fast?
