Question 1
What occurs when a branch is mispredicted?
- The processor proceeds without change
- The pipeline is flushed
- No impact on performance
💡 Hint: Consider what happens to instructions in the pipeline.
Question 2
True or False: A branch misprediction can lead to significant delays in a processor's operation.
- True
- False
💡 Hint: Think about how instructions are executed in a pipeline.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a processor that mispredicts a branch in a highly iterative loop. Analyze how this could affect the overall efficiency of a program running on this processor.
💡 Hint: Think about how many cycles might be wasted in an iterative process.
Question 2
Design a brief experimental setup to compare the effects of static and dynamic branch prediction on pipelined performance. What metrics would you consider?
💡 Hint: Consider how branch behavior might influence the effectiveness of each prediction strategy.
