Question
An ISA has the following instruction group:
If a CPU that runs at 1 GHz implements this ISA, what is the average rate of instructions execution, IPS (Instructions Per Second)?
If a benchmark program has an execution time of 1 second when it runs on the CPU of part (b), what is the IC of that program?
If you have the chance to improve the CPI of, just, one of the 4 instruction groups, which group would you improve? Why?
