A pipeline with 8 stages runs a program. Assume 20% of instructions are branches, and "branch not taken" holds for branch prediction. Further assume that 30 percent of the branches are predicted correctly, and there is an average penalty of 2 cycles for each mispredicted branch. Additionally, 4 percent of the total instructions incur an average of 1.5 stalls each. What would be the CPI of running program P on this pipeline?
