Question 1
What happens during a control hazard?
- The processor stalls
- All instructions are fetched
- The pipeline continues normally
💡 Hint: Think about the decisions processors must make when branching occurs.
Question 2
True or False: Stalling improves pipeline efficiency.
- True
- False
💡 Hint: Consider the effect of wasted time when waiting for conditions.

Challenge Problems
Push your limits with challenges.
Question 1
Imagine a processor using dynamic branch prediction with a history of the last five branches taken. If the last three branches taken were taken, what approach might the processor take for a new branch instruction?
💡 Hint: Reflect on the patterns of past behaviors influencing present decisions.
Question 2
Evaluate a scenario where a program has many independent branches versus a tight loop of branches. How would the control hazard penalties differ?
💡 Hint: Consider the frequency and the nature of program execution patterns.
