Question 1.
What is the main purpose of an ISR?
Show hintHide hint
Think about what ISRs need to accomplish when triggered.
Question 2.
What does it mean for an ISR to have low-latency execution?
Show hintHide hint
Consider why speed is important when responding to interrupts.
3Question 3.
What does an ISR do when it is triggered?
- Stops all CPU processing
- Acknowledge the interrupt and handle the event
- Creates a new interrupt
Show hintHide hint
Focus on what the ISR's primary role is.
4Question 4.
True or False: ISRs can take a long time to execute.
- True
- False
Show hintHide hint
Consider the efficiency aspect of handling interrupts.
Question 5.
Imagine a system running multiple ISRs. Discuss how you would design a strategy for context switching to handle high-frequency interrupts efficiently.
Show hintHide hint
Think about the balance between speed and handling multiple events.
Question 6.
Design an embedded system where multiple sensors use ISRs for reading data, ensuring that the system does not suffer from latencies. Outline your approach.
Show hintHide hint
Consider resource management while handling multiple data sources.
