Question 3 [20 points]: A program has a CPI equal to

Question 3 [20 points]: A program has a CPI equal to 2.0 when running a program P on a machine that has a clock frequency equal to 3 GHz. The hardware designer was asked to modify the hardware so that the CPU time of P becomes 1/3 of the original CPU time. The machine's ISA should stay the same. The designer first reduced the CPI of P to 1.0 by changing the implementation of the instructions. (a) [14 points] What changes should the designer make to the clock frequency to get to the 1/3 reduction? Assume that changes in the clock frequency will not affect the CPI. (b) [6 points] What was the resulting percentage change in the processor's dynamic power as a result of the change in item (a) above assuming there was no change in the capacitive load
