4.29 This exercise examines the accuracy of various branch predictors for the following repeating pattern (e-g, in a loop) of branch outcomes: T, NT, T, T, NT 4.29.1 [5] What is the accuracy of always-taken and always-not-taken predictors for this sequence of branch outcomes? 4.29.2 [5] What is the accuracy of the 2-bit predictor for the first four branches in this pattern, assuming that the predictor starts off in the bottom left state from Figure 4.62 (predict not taken)
