Do new devs get fired if they can't solve a certain bug? CPU execution time = = CPU clock cycles x Clock cycle. On the surface, MIPS calculation is very simple you measure the number of seconds the CPU is busy on a certain workload and then multiply by a configuration-dependent MIPS factor. This is because MIPS donot track the execution time. Primary Cache, Miss Rate/Instruction = 7% L-2 Cache access time = 15ns. I CPU Average CPI/Execution Time For a given program executed on a given machine (CPU): CPI = Total program execution cycles / Instructions count CPU clock cycles = Instruction count x CPI CPU execution time = = CPU clock cycles x Clock cycle = Instruction count x CPI x Clock cycle This value is of course purely theoretical estimate, as modern CPU doesn't work like that (1 instruction = 1 cycle).
