(8pts) Consider three different processors Pi, P2, and Ps executing the same instruction set with the clock rates and CPIs given in the following table. Processor Clock Rate CPI 2.2 GHz 1.6 P2 1.7 GHz 1.2 P3 2.9 GHz 2.4 Answer the following questions: (a) Which processor has the highest performance (as defined in class)? (b) If the processors each execute a program in 12 seconds, find the number of instructions and the (c) We are trying to reduce the current time of 12s by 30% but this leads to an increase of 20% in d) Using the results above, explain why it is inappropriate to compare the performance of each number of cycles for each the CPI. For each processor, what clock rate should we have to achieve this time reduction? processor using the Clock Rate as a lone metric. What are the three key factors that affect processor. performance
