Question 1.
What is a non-vectored interrupt?
Show hintHide hint
Think about how it differs from vectored interrupts.
Question 2.
Why might non-vectored interrupts introduce latency?
Show hintHide hint
Consider the shared ISR scenario.
3Question 3.
What does a non-vectored interrupt require the CPU to do?
- Point directly to ISR
- Identify the source post-trigger
- Ignore the source
Show hintHide hint
Consider how an ISR is used.
4Question 4.
Non-vectored interrupts are typically less efficient than vectored interrupts. True or False?
- True
- False
Show hintHide hint
Think about the implications of shared ISRs.
Question 5.
You are designing a simple thermostat with multiple sensors (temperature, humidity). Explain how you would implement non-vectored interrupts to handle readings from these sensors.
Show hintHide hint
Think about how to monitor each sensor's status.
Question 6.
Discuss the potential impact on system performance when using non-vectored interrupts in a high-frequency data logging application.
Show hintHide hint
Evaluate the trade-offs between speed and system simplicity.
