Question 1.
What does RMS stand for?
Show hintHide hint
Focus on the prioritization aspect.
Question 2.
Why is scheduling important in real-time systems?
Show hintHide hint
Consider tasks like alarms and robotic motions.
3Question 3.
What is the main principle of Rate Monotonic Scheduling?
- Prioritizes tasks with longer periods
- Prioritizes tasks with higher frequencies
- Assigns equal priority to all tasks
Show hintHide hint
Think about how urgent tasks are handled.
4Question 4.
True or False: RMS can lead to task starvation in some systems.
- True
- False
Show hintHide hint
Consider what happens in a busy system.
Question 5.
Consider a scenario with four tasks: A (Period = 3ms), B (Period = 5ms), C (Period = 8ms), and D (Period = 12ms). Calculate the CPU utilization and determine if RMS can guarantee all deadlines.
Show hintHide hint
Use the worst-case CPU utilization criteria for RMS.
Question 6.
A system has three tasks: X (20ms), Y (50ms), and Z (70ms). If each task needs to execute twice during a 100ms time frame, explain how RMS will handle them.
Show hintHide hint
Visualize the task execution slots.
