Question 1.
What is PendSV primarily used for?
Show hintHide hint
Think about how tasks are paused and resumed.
Question 2.
What role does SysTick play in the Cortex-M0?
Show hintHide hint
Recall how timing is crucial in various applications.
3Question 3.
What does PendSV stand for?
- Pendable Service Interrupt
- Pending Service Interrupt
- Processable Service Interrupt
Show hintHide hint
Think about its functionality in task management.
4Question 4.
True or False: SysTick is used for generating one-time interrupts only.
- True
- False
Show hintHide hint
Reflect on its naming; 'Tick' implies recurrence.
Question 5.
Design a simple embedded system using PendSV and SysTick that manages three tasks: temperature logging, LCD display updates, and alarm notifications. Explain how these components interact.
Show hintHide hint
Consider how often each task needs to run simultaneously.
Question 6.
Evaluate the performance impact of excessive context switching versus optimizing task intervals with SysTick. Discuss potential solutions to manage this in a real-time system.
Show hintHide hint
Think about balancing task loads.
