for (i=0; i <1000; i++) { } if ((i mod 2) ==0) { } a) The code results in at least two conditional branches. Using a one-bit predictor for branch prediction, what is the prediction accuracy for the loop and for the if statement? Assume the initial prediction is to take the branch. // Do some stuff, no branches here b) Using the two-bit predictor shown by the finite state automaton below, what is the prediction accuracy for the loop and the if statement? Assume you start in state 00. T NT 00 Predict taken 10 Predict not taken NT T T NT 01 Predict taken TINT 11 Predict not taken c) Would a correlation predictor help in this case? for (i=0; i <1000; i++) { } if ((i mod 2) ==0) { } a) The code results in at least two conditional branches.
