The Branch Target Buffer (BTB) is a hardware mechanism to aid dynamic branch prediction in a pipelined processor. Which of the following is typically stored in the Branch Target Buffer?

Consider the classic 5-stage pipeline for LC-5200 as described in the textbook without any hardware branch prediction mechanisms. The outcome of the branch instruction (e.g., beq) is not resolved until the Execute (EX) stage. Give one reason why the decision on whether or not to branch should not be resolved in the Fetch (IF) stage. Give your answer in under 50 words.

Sean decides to modify this pipeline by combining the EX and MEM stages. The new per stage delay will be the sum of the per stage delays of the 2 combined stages. What will the pipeline’s new frequency be in MHz? Give your answer as a whole number in MHz without units.

Consider the following 9-stage pipeline with data forwarding available only from the “EX2” and “Write Back” stages to the “Register file Read” stage. Registers are read during RR, and addition results are available in EX1. Recall the hardware implementation of data forwarding between stages is purely combinational.

A sample of 22 fifth grade students has a grade point average of 3.0. We know that the grade point average of all fifth grade students over the last five years is 2.75. We are interested in whether the grade point average of the 22 students is significantly different from the 2.75 GPA average from the last five years. What statistical test should be used to answer this research question?
