8. Consider two different machines, with two different instruction sets, both of which have a clock rate of 200 MHz. The following measurements are recorded on the two machines running a given set of benchmark programs: a) Determine the effective CPI, MIPS rate, and execution time for each machine. b) Comment on the results.
