Homework Answers
Branch prediction is a technique in Computer Architecture that is used to guess the way a branch will go before the actual result (or) A branch predictor in a processor attempts to guess the outcome of a conditional operation before the most likely result(or) branch prediction is the ability to guess the way a branch will execute. It is used to improve the flow of instruction pipeline.
Example:
It is a two bit branch prediction for looping

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...

Give an example of data that could be obtained to make a prediction. Discuss lurking variables and why the correlation may not imply causation. Correlation and Regression is typically most students’ favorite area in statistics because it gives the ability to make predictions. Give an example of data that could be obtained to make a prediction. Discuss lurking variables and why the correlation may not imply causation.

Suppose that a machine with a 5-stage pipeline uses branch prediction. 12% of the instructions for a given test program are branches, of which 84% are correctly predicted. The other 16% of the branches suffer a 4-cycle mis-prediction penalty. (In other words, when the branch predictor predicts incorrectly, there are four instructions in the pipeline that must be discarded.) Assuming there are no other stalls, develop a formula for the number of cycles it will take to complete n lines...

(25 points) Consider a 1-bit and a 2-bit predictor. In the table below, indicate the prediction for the branch and whether the prediction is correct. For the 1-bit predictor use the notation"1 for taken, and "0 for not taken states. For the 2- bit predictor, use "11 for strongly taken state, "10 for weakly-taken state.'00 for strongly-not-taken state, and "01" for weakly-not-taken state. Assuming the first entry in the table, fill in the predictor's state after branch resolution for each...
