3. (6 pts This exercise examines the accuracy of various branch predictors for the following repeating pattern (e.g. in a loop of branch outcomes: T, T, T, NT, T, NT. Note: include a brief explanation for each number in your answer. a. What is the accuracy of always-taken and always-not-taken predictors for this sequence of branch outcomes? b. What is the accuracy of the two-bit predictor for the first five branches in this pattern, i e. T, T, T, NT, T? Assume that the predictor starts off in the bottom left state from Figure 4.63 (predict not taken) c. What is the accuracy of the two-bit predictor if the pattern is repeated forever?

    1. Suppose we have a 5-stage pipeline CPU and run the following instructions: or $tl, $t2, $t3 or $t2, $tl, $t4 or $tl, $tl, $t2 1.1. What dependencies are there in the code? 1.2. Suppose there is no forwarding. What hazard may happen? Draw the pipeline diagram and insert stall (nop) to prevent these hazard. 1.3. If the pipeline has full forwarding. Are there still hazard? If so, draw the pipeline diagram and insert stall (nop) to prevent the hazard....

    Ch04.4. [6 points] Branch Prediction. Consider the following sequence of actual outcomes for a single static branch. T means the branch is taken. N means the branch is not taken. For this question, assume that this is the only branch in the program. TTTNTNTTTNTNTTTNTN Assume that we try to predict this sequence with a Branch History Table (BHT) using one-bit counters. The counters in the BHT are initialized to the N state. Which of the branches in this sequence would...
