The CPU time equation is as follows, CPI means Clock cycles per instruction: CPU Time = (Instructions Program)*(CPI)*(Seconds/Clock cycle). For each of the three factors in the CPU Time equation, answer the following questions (1) Can loop unrolling ALONE improve this factor, worsen this factor, or cannot affect this factor? (2) If loop unrolling either improves or worsens the factor, how does this occur? Once a loop has been unrolled, which factor(s) of the CPU Time equation can be improved, worsened, or cannot be affected through the application of instruction scheduling? Explain
