please show work with formula's

  1. Consider the following data for three processors operating on a program:

Processor

Clock Rate

Number of Instructions

Execution Time

P1

3.4 Ghz

8.3 x 109

15s

P2

3.6 Ghz

7.7 x 109

13s

P3

3.7 Ghz

7.9 x 109

13s

  1. What is the CPI for each processor?

  1. Suppose we wanted to improve processor P1s performance by overclocking (that is, manually setting a faster clock rate in the CPU). What clock rate is required to make P1 perform as well as the other two processors?

  1. What risks arise from overclocking? Find at least two dangers from overclocking by searching the Internet.
