Consider a computer A executes some program and the analysis performed on such system reveals that it takes: Instruction Frequency | Clock Cycles ALU 47 2 LOAD 21 5 STORE 16 5 BRANCH JUMP wwul a. Assuming a clock frequency of 3.4 GHz, calculate the average CPI for the above program. b. Assuming a clock frequency of 3.4 GHz, calculate the throughput for the above system. C. If the clock frequency is increased by 20%, which results in the increment of CPI of ALU of 50% and LOAD instruction of 20%, while all other instructions executing with the same CPI, calculate the average CPI, throughput and the average speedup with respect to above. Determine which case is better: pervious system with frequency 3.4 or this new revised system
