The results of the SPEC CPU 2006 bzip2 benchmark running on an AMD Barcelona has an instruction count of 2.389E12, an execution time of 750 s, and a reference time of 9650 s. a. Find the CPI if the clock cycle time is 0.333 ns. b. Find the SPEC ratio. c. Find the increase in CPU time if the number of instructions of the benchmark is increased by 10% without affecting the CPI. d. Find the increase in CPU time if the number of instructions of the benchmark is increased by 10% and the CPI is increased by 5%. e. Find the change in the SPEC ratio for the change in (d)
