Question 1 Simulate GSelect below. At each time T below, index into the GSelect table at T using the PC and GHR at T and write the prediction (T or N). Then write the new GHR and new GSelect state at timestamp T+1 given the actual branch outcome. We provide the initial predictor state at Time 0. The GHR is two bits, with the rightmost bit being the newest. The PC hash is PC[2] (e.g., the hash of 0x0004 is 1).
