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. (total 60 points, 10 points each) a. find the cpi if the clock cycle time is 0.333 ns. b. find the increase in cpu time if the number of instructions of the benchmark is increased by 10% without affecting the cpi. c. 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%. d. suppose that we are developing a new version of the amd barcelona processor with a 4 ghz clock rate. we have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15%. the execution time is reduced to 700 s. find the new cpi. e. this cpi value is larger than obtained in a. as the clock rate was increased from 3 ghz to 4 ghz. determine whether the increase in the cpi is similar to that of the clock rate. if they are dissimilar, why? f. by how much has the cpu time been reduced?
