Consider two different hardware implementations M1 and M2 of the same instruction set. There are three classes F, I and N of instructions in the instruction set. M1's clock rate is 600 MHz and M2's clock cycle is 2 ns The ave rage CPI for the three instruction classes on M1 and M2 are as follows. Instruction Cla CPI for M2 Comments 4.0 3.5 Floating-point 5.0 Integer Arithm etic 2.0 Non-arithmeti 2.4 If 50% of all instructions executed in a certain program are from Class N, and the rest are divided equally among F and I, which machine is faster and by what factor?
