SPEC CPU2017 is used for a 2 GHz processor, showing an execution time of 4,000 ns, with a benchmark average CPI of 4 a. The aim is to reduce execution time by 20%, keeping CPI same but changing hardware with a 3 GHz processor instead. How many instructions were executed now? b. With the instruction count found above and CPI, what clock frequency will achieve a further reduction of 10% in execution time vs. that in question a)?
