Challenge Problems
Push your limits with challenges.
Question 1
Design a task set with three tasks. Task A has a period of 6 ms and a WCET of 2 ms, Task B has a period of 4 ms and a WCET of 1 ms, and Task C has a period of 8 ms and a WCET of 3 ms. Determine if the system can be scheduled under EDF.
💡 Hint: Focus on computing the total utilization based on WCET and period.
Question 2
In a real-time system with EDF scheduling, explain how you would manage resource contention among tasks and implement priority inversion solutions.
💡 Hint: Consider how priority inversion affects task scheduling when multiple tasks access shared resources.
