Build Your Own RealTime Operating Systems from first principles

   Watch Promo

This course teaches you how to build a Real-Time Operating Systems through intensive practice and theory. It starts by getting you excited through an introduction to the internals of a Real-Time Kernel on ARM Processors, which you shall implement yourself in code.Then we move on to learn all there is about Real-Time Operating Systems, their various parts, how they work and then we finally build our own Real-Time Operating System exploring different scheduling algorithms and Inter-Thread communication tools.

At the end of this course you should be able to build your own Real-Time Operating System from scratch, give your own lecture on Real-Time Operating Systems, be able to build a Round-Robin Scheduler, be able to build a Periodic Scheduler, be able to calculate the CPU utilization of your RTOS, be able to build an OS Kernel etc. Please see the course curriculum section to find out all the amazing content awaiting you.
