Question 1

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

πŸ’‘ Hint: Think about how urgent tasks are handled.

Question 2

True or False: RMS can lead to task starvation in some systems.

  • True
  • False

πŸ’‘ Hint: Consider what happens in a busy system.

Challenge Problems

Push your limits with challenges.

Question 1

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.

πŸ’‘ Hint: Use the worst-case CPU utilization criteria for RMS.

Question 2

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.

πŸ’‘ Hint: Visualize the task execution slots.
