Question 1.
What does the BTB stand for?
Show hintHide hint
Think about what cache helps with branches.
Question 2.
What is the primary role of the BTB?
Show hintHide hint
Consider its function in instruction fetching.
3Question 3.
What is a Branch Target Buffer (BTB)?
- Cache for data addresses
- Cache for branch target addresses
- Memory for CPU execution
Show hintHide hint
Consider the purpose of the cache in good performance.
4Question 4.
True or False: A BTB can help reduce pipeline stalls.
- True
- False
Show hintHide hint
Reflect on the impact of branch prediction techniques.
Question 5.
Design a simple BTB structure for a processor that shows how it stores and retrieves branch target addresses. What considerations would you need to take into account?
Show hintHide hint
Consider cache effectiveness and potential size limits.
Question 6.
Analyze a code snippet involving multiple nested loops and conditional branches. How would a BTB optimize performance in this case, and what metrics would you use to prove its effectiveness?
Show hintHide hint
Think of how often branches occur in loops.
