a. (5 points) In general, branch prediction works well because most of the time, conditionals are part of loops that iterate many times with the result that the branch will be taken back to the start of the loop. Branch prediction does not work well when code consists of only one- pass logic. But, how would you compare the performance of branch prediction in this situation with a simple sequential system where branch prediction is not used? b. (5 points) What is PC-relative addressing? Why is it used? c. (7 points) Using and, or, and not logical gates, build a three-input circuit that outputs T of a, b, and c. d. (3 points) Give three things that could determine the next value of the PC
