Question 1.
Define interrupt latency.
Show hintHide hint
Think about the time taken from when an event happens to when it is processed.
Question 2.
What does ISR stand for?
Show hintHide hint
Consider what happens during an interrupt.
3Question 3.
What is interrupt latency?
- Time taken to handle an interrupt
- Time between receiving and starting ISR
- Speed of CPU processing
Show hintHide hint
Focus on the delay aspect of interrupts.
4Question 4.
True or False: Less complex states lead to higher interrupt latency.
- True
- False
Show hintHide hint
Consider what happens when there’s less information to store.
Question 5.
Analyze the impact of a system with a high interrupt latency in an automotive safety feature. How does it affect performance?
Show hintHide hint
Think about the consequences of waiting too long in crucial situations.
Question 6.
Design a basic ISR that minimizes latency. What specific strategies would you implement?
Show hintHide hint
Consider how your choices can streamline the ISR process.
