Figure belоw shоws а cоntrol-flow diаgrаm with a difficult-to-predict branch, “Branch X”.  Before X, there is a part of the loop body containing 90 instructions.  Furthermore, both the “Taken (T)” and “Not-Taken (NT)” path of X contains 10 instructions each, after which the control flow converges.  This code gets executed a large number of times.   To mitigate performance penalty of branch mispredictions, we are considering predicated execution for X.   Recall that, with predicated execution, both T and NT paths will be executed regardless of the branch direction.  We will execute this code on a 4-wide processor with 25-stage deep pipeline, so the branch misprediction penalty is approximately 100 instructions. Consider the program executes the loop 1 million times.  Therefore, with perfect prediction, we would expect a total of 100 million instructions to be executed.
