1.12 The results of the SPEC CPU2006 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 9650s. 1.12.1 Find the CPI if the elock cycle time is 0.333 ns. 1.12.3 Find the increase in CPU time if the number of instructions of the benchmark is increased by 10% without affecting the CPI. 1.12.4 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%. 1.12.7 This CPI value is larger than obtained in 1.11.1 as the clock rate was increased from 3GHz to 4GHz. Determine whether the increase in the CPI is similar to that of the clock rate. I they are dissimilar, why
