Question 1.
What are branch instructions?
Show hintHide hint
Think about conditional statements in programming.
Question 2.
Define control hazard.
Show hintHide hint
Consider what happens when you cannot determine the flow of execution.
3Question 3.
What is a control hazard?
- A type of delay caused by branches
- A performance optimization technique
- A program syntax error
Show hintHide hint
Think about situations where instruction flow is paused.
4Question 4.
True or False: Static branch prediction adapts based on prior outcomes.
- True
- False
Show hintHide hint
Consider whether the prediction changes over time or stays fixed.
Question 5.
Design a simple algorithm that minimizes branch mispredictions using historical data. Outline how you would implement this in a hypothetical processor.
Show hintHide hint
What would help in recognizing trends in branch behavior?
Question 6.
Evaluate the impact of increased pipeline depth on branch latency and overall processor performance. Consider how different hazard types contribute to this impact.
