Need some help with Computer Organization and Architecture

P1 has a 4.18 GHz clock rate and a CPI of 2.07. P2 has a 2.52 GHz clock rate and a CPI of 5.14. a. (4 pts) What's the performance of each processor expressed in instructions per second (IPS)? Show the equations you used. Performance(P)= Clock Rate/ CPI P1: P2: Which processor has the highest performance? OP1 OP2 b. (4 pts) If the processors each execute a program in 15 seconds, find the number of cycles for each processor. Your answer should be in scientific notation, one non- zero digit to the left of the decimal, let's say 2 digits to the right, and multiplied by a power of 10. For example, 1.23 x 109. P1: cycles P2: cycles c. (4 pts) And now find the number of instructions executed in this time for each processor. Make sure you use enough digits of significance to uncover any difference; don't let rounding make it look like they have run the same number if in fact they have not P1: cycles P2: cycles d. (4 pts) We discover we can reduce the execution time for each processor by 20% but it leads to an increase of 10% in the CPI. What is the new execution time for both processors? Always show your formulas. New execution time: e. (4 pts) What is the new CPI for each processor? P1 new CPI: P2 new CPI: f. (4 pts) We want to reduce the original execution time of each CPU by 20%. But this time the CPIs remain unchanged. Recalculate the clock rate (cycles/sec or GHz) that will be required to achieve this time reduction. We calculated the total instructions required to be processed above; that won't change. What's the new clock rate in a max of 4 digits of significance? Pl: P2
