What will be L1 miss rate? I think it is 80/3600 ,but then answer did not match. But if i take 80/2000,then it matches with the given answer

Consider that branch outcomes are determined in the EX stage and the pipeline uses some prediction mechanism. If the misprediction happens, how many stall cycles gets int...

anyone elaborate the reason for each stall cycles.
