Question: Answer to question 5? 5. Suppose for the problem in question 4. Load/store operations were made to take 1 cycle. without lengthening the cycle time.

5. Suppose for the problem in question 4. Load/store operations were made to take 1 cycle. without lengthening the cycle time. What would be the speedup due to that optimization? 4. For a particular computer, the CPI for certain types of instructions is as follows: ALU operations, 2 cycles, make up 25% of dynamic (run-time) instruction count Load/store operations, 10 cycles, 30% of dynamic instruction count Control flow. 3 cycles, 20% of dynamic instruction count All other instructions, I cycle What is the average CPI? Suppose there is an optimization in which the CPI of load/store is reduced to 5. but cycle time is lengthened by 20%. What is the speedup due to this optimization
