Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a task has a WCET of 10ms and a period of 50ms, what is its utilization? Is it schedulable with a maximum utilization of 60%?

💡 Hint: Remember the utilization formula!

Challenge 2 Hard

A real-time system has tasks that need to execute every second. If one task takes 800ms on average plus 150ms of jitter, what is the maximum delay experienced?

💡 Hint: Calculate total time considering the additional uncertainties caused by jitter.
