Fоr this questiоn, аssume thаt yоu decide to use а tournament predictor with 2-bit saturating counters (as shown in figure 1 below) for branch predictions in your processor implementation. Figure 2 below shows an instance of the tournament predictor with values for two branches B1, and B2. Assume that B1, and B2 exhibit dynamic behavior i.e., the outcome of the branch depends on the results from other instructions. For simplicity, the index of the global predictor, local predictor, and the selector are labeled as Bi_H, Bi_A, and, Bi_A respectively, where B_H represents the address from branch history, B_A represents branch address, and i ∈ {1, 2}. Figure 1: 2-bit saturating counter Figure 2: Tournament Predictor showing two branches B1 and B2 Assume that the selector uses a single bit to choose between global predictor - 1 and local predictor - 0. If B1 instruction is issued, what will be the prediction for B1?
