Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a set of three periodic tasks with the following parameters: Task A (C=1, T=5), Task B (C=2, T=10), Task C (C=1, T=4). Can all tasks be scheduled using Rate Monotonic scheduling? Justify your answer with calculations.

💡 Hint: Use the utilization formula for each task to find total utilization.

Challenge 2 Hard

How does aperiodic tasks complicate scheduling in a real-time system? Propose a solution to this complication.

💡 Hint: Think about reserving CPU time differently to manage unpredictable tasks.
