Q4. Assume a C program has the following amount of instructions: Calculate the following: a. Total CPU clock cycles needed for the program b. Overall CPI c. CPU time needed for the program assuming the clock rate is 1kHz Q5. Suppose we have made the following measurements: Frequency of FP operations =50% Average CPI of FP operations =4.25 Average CPI of other instructions =1.33 Frequency of FPSQR=5% CPI of FPSQR=23 Assume that the two design alternatives are to decrease the CPI of FPSQR to 2.5 or to decrease the average CPI of all FP operations to 2.5. Compare these two design alternatives using the processor performance equation. Which design is better and why
