The table below shows the distribution of each instruction type on a processor running with a 2 GHz clock frequency Instr Proportion CPI (baseline) CPI (opt #1) CPI (opt #2) Load/Store Branch Mul/Div Other Total 24% 30% 12% 34% 100% 3 Question 3.A Baseline CPI (4 points) What is the average CPI of the baseline processor? Question 3.B Optimization (6 points) With some optimization, and the support of some extra logic, the microarchitecture can decrease the load and store CPI to 2 and branch CPI to 1 and decrease the mul/div logic to a CPI of 7 (option #1). Alternatively, the extra logic that can be spent can be used to optimize load and store CPI to 3 and the mul/div logic to support CPI of 1 (option #2) What is the CPI speedup of each optimization relative to the baseline design? Which optimization is better to improve performance
