A pipeline with 15 stages runs a program P having 3,221 instructions. Branches comprise 13 percent of the instructions, and the “branch not taken” assumption holds for branch prediction. Further assume that 40 percent of the branches are predicted correctly, and there is an average penalty of 1.2 cycles for each mis-predicted branch. Additionally, 2 percent of the total instructions incur an average of 1.2 stalls each. Calculate the CPI(clocks per instruction) of P on this pipeline
