PROBLEM III Consider two machines: . Machine A with 1GHz clock rate. . Machine B with 2GHz clock rate Both machines implement the same instruction set architecture. The machines have the following speci- fications: Instruction Instruction Machine A cycles for Machine B cycles for class Arithmetic Load/Store Cond. Branch Branch frequency 40% 25% 25% 10% instruction class 1.2 1.5 instruction class 1.1 2.0 What is the overall CPI for each machine? Which machine is faster
