Assume the computer resolves branching in the 3rd stage. We predict that 50% of time branch is taken. (For other instructions our prediction is 100%). Assume that in reality 20% instructions are conditional branches. (30) a. What would be the average CPI (Cycles per Instruction) for this computer? b. What would be the CPI if we resolve at the 3rd stage but predict 90% branch taken? c. What is the speedup? Please include formulas used for calculations
