1.11 The results of the SPEC CPU2006 bzip2 benchmark running on an AMID Barcelona has an instruction count of 2.389E12, an execution time of 750s, and a reference time of 9650 s. 1.11.1 [5] Find the CPI ifthe clock cycle time is 0.333 ns. 1.11.2 (5] Find the SPECratio. 1.11.3 [5] Find the increase in CPU time ifthe number ofnstructions of the benchmark is increased by 10% without affecting the CPI. 1.11.4 [5] Find the increase in CPU time ifthe number ofinstructions of the benchmark is increased by 10% and the CPI is increased by 5%. 1.11.5 [5] Find the change in the SPECratio for this change. 1.11.6 [10] Suppose that we are developing a new version of Barcelona processor with a 4GHz 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 700s and the new SPECratio is 13.7. Find the new CPI the AMD 111.7 [10] This CPI value is larger than obtained in 1.11.1 as the clock rate was increased from 3 GHz to 4GHz. Determine whether the increase in the CPl is similar to that of the clock rate. Ifthey are dissimilar, why? 111.8 [5] By how much has the CPU time been reduced? 1.11.9 [10] For a second benchmark, libquantum, assume an execution time of 960 ns, CPI of 1.61, and clock rate of 3 GHz. If the execution time is reduced by an additional 10% without affecting the CPI and with a clock rate of 4 GHz, determine the number of instructions. 1.11.10 [10] Determine the clock rate required to give a further 10% reduction in CPU time while maintaining the number of instructions and with the CPI unchanged. 1.11.11 [10]
