How to Prioritize RTOS Tasks (and Why it Matters)

There is an optimal method of assigning fixed priorities to a set of RTOS tasks and interrupt service routines. When a real-time operating system is used without assigning task priorities in this way, only one task (or, more commonly, ISR) may be guaranteed to meet all of its deadlines. This course explains how and why to use this optimal method to allow a critical set of tasks and ISRs to meet all of their deadlines even during transient overload periods.

Video Excerpts

There are two short video excerpts from this important lecture available on YouTube:

• Excerpt 1: Priority Inversion on Mars
• Excerpt 2: Accounting for Context Switches

Although each of these short clips stands more or less on its own, the valuable information presented will make even more sense within the context of the full 2-hour lecture.
