Barcelona has an instruction count of 2.389E12, an execution time of 750 s, and areference time of 9650 s.1.11.1 [5] <§§1.6, 1.9> Find the CPI if the clock cycle time is 0.333 ns.1.11.2 [5] <§1.9> Find the SPECratio.1.11.3 [5] <§§1.6, 1.9> Find the increase in CPU time if the number of instructionsof the benchmark is increased by 10% without affecting the CPI.1.11.4 [5] <§§1.6, 1.9> Find the increase in CPU time if the number of instructionsof the benchmark is increased by 10% and the CPI is increased by 5%.1.11.5 [5] <§§1.6, 1.9> Find the change in the SPECratio for this change.1.11.6 [10] <§1.6> Suppose that we are developing a new version of the AMDBarcelona processor with a 4 GHz clock rate. We have added some additionalinstructions to the instruction set in such a way that the number of instructionshas been reduced by 15%. The execution time is reduced to 700 s and the newSPECratio is 13.7. Find the new CPI.1.11.7 [10] <§1.6> Th
