2. (10 points) For the purpose of solving a given application problem, you benchmark a progranm on two computer systems. On system A, the object code executed 20 million Arithmetic Logic Unit operations (ALU ops), 40 million load instructions, and 30 million branch instructions. On system B, the object code executed 25 million ALU ops, 50 million loads, and 20 million branch instructions. In both systems, each ALU op takes 2 clock cycles, each load takes 4 clock cycles, and each branch takes 6 clock cycles. (a) Compute the relative frequency of occurrence of each type of instruction executed in both systems. Show all your work. (b) Find the CPI for each system. Show all your work. (c) Assuming that the clock cycle rate on system B is 15% faster than the clock rate on system A, which system is faster for the given application problem and by how much percent? Justify your answer quantitatively and show all your work
