Consider two different implementations, I1 and 12, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. I1 has a clock rate of 6GHZ, and 12 has a clock rate of 3GHZ. The average number of cycles for each instruction class on 1 and 12 is given in the following table: Class CPI on 1 CPI on 12 C1 Usage C2 Usage C3 Usage 2. 40% 40% 50% 3 40% 20% 25% 2 20% 40% 25% The table also contains a summary of average proportion of instruction classes generated by three different compilers. C1 is a compiler produced by the makers of 1, C2 is produced by the makers of 12, and the other compiler is a third-party product. Assume that each compiler uses the same number of instructions for a given program but that the instruction mix is as described in the table. Using C1 on both 1 and 12, how much faster can the makers of 1 claim 1 is compared to 12? Using C2, how much faster can the makers of 12 claim that 12 is compared to 1?

Question
Consider two different implementations, 1 and 12, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. I1 has a clock rate of 6GHZ, and 12 has a clock rate of 3GHZ. The average number of cycles for each instruction class on 1 and 12 is given in the following table: CPI on 12 C1 Usage C2 Usage Class CPI on 11 C3 Usage A 2. 40% 40% 50% 40% 20% 25% 5 20% 40% 25% The table also contains a summary of average proportion of instruction classes generated by three different compilers. C1 is a compiler produced by the makers of 1, C2 is produced by the makers of 12, and the other compiler is a third-party product. Assume that each compiler uses the same number of instructions for a given program but that the instruction mix is as described in the table. Using C1 on both 1 and 12, how much faster can the makers of 1 claim 1 is compared to 12? Using C2, how much faster can the makers of 12 claim that 12 is compared to 1?
