Mechatronics 15: RTOS

Introduction to Real-Time Operating Systems

An RTOS provides the framework to manage multiple, complex tasks with strict timing deadlines. Its core value is not just speed, but **predictability**. This interactive app will help you visualize the key concepts that make real-time systems possible.

Use the tabs above to navigate. The **Scheduler Sim** is the best place to start for hands-on learning!

Task Execution Timeline

This chart shows which task is running on the CPU at each time "tick." Notice how higher priority tasks interrupt (preempt) lower priority ones.
