Challenge Problems
Push your limits with advanced challenges
Suppose you have three tasks with the following characteristics: Task A with a period of 10ms and execution time of 3ms, Task B with a period of 20ms and execution time of 5ms, and Task C with a period of 15ms and execution time of 2ms. Analyze their schedulability under EDF.
💡 Hint: Remember the utilization calculation for EDF.
Let’s assume that you have an overloaded system where tasks A, B, and C are causing 110% CPU utilization. Discuss how the behavior of EDF and LLF might differ in terms of task execution.
💡 Hint: Consider the difference between total deadlines being missed vs. operational efficiency.
