Tools Sign Exercise 1.13 Suppose that we are developing a new version of the AMD Barcelona proces- sor 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% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. ts Name Execution Time (seconds) Reference Time (seconds) SPECratio a. bzip2 b. E0 700 9650 13.7 620 10490 16.9 1.13.1 [10] 1.8> Find the new CPI 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why? 1.13.3 15] How much has the CPU time been reduced? FUJITSU
