Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600MHz.Computer B has a CPI of 2.5 and can be run at a clock rate of 750 Mhz. Wehave a particular program we wish to run. When compiled for computer A, thisprogram has exactly 100,000 instructions. How many instructions would theprogram need to have when compiled for Computer B, in order for the twocomputers to have exactly the same execution time for this program?
Consider a computer running a program that requires 250 seconds, where 70 seconds is spent executing FP instructions, 55 seconds for INT operations, 85 seconds for load/save operations, and 40 seconds for branch instructions.

Consider a multilevel computer in which levels are vertically stacked, with the lowest level being level 1. Each level has instructions that are m times as powerful as those of the level below it; that is, one level r instruction can do the work of m instructions at level r-1. However, n instructions at level r-1 are required to interpret each instruction at level r. Given this, answer the following questions: If a level 1 program requires k seconds to run, how long would the equivalent program take to run at levels 2, 3 and 4. Express your answer in terms of n, m, and r. What is the performance implication for the program if n > m? Conversely, what is the implication if m > n? Which case do you think more likely? Why?
