Consider two processors P1 and P2 executing the same instruction set. And their clock rate and CPI are like below: Clock rate CPI P1 3 GHz 1.5 P2 4 GHz 2 For the two processors, solve the following problems. Round off the calculated results to two decimal places if needed. a. Which processor has the highest performance expressed in instructions per second? b. Suppose that both processors took 100 seconds to run a program. We want to achieve 2x speedup in running this program on both processors by increasing clock frequency. But, we found that the frequency increase led to an increase of CPI by 10% and 20% for P1 and P2, respectively. So, we adjusted the clock frequency to accommodate the new CPI. What would be the final clock frequency of each of the two processors
