Real time training

Real time Linux training

Real-time applications are applications that deliver results within a certain time. This concept is called determinism, according to me which nothing happens by chance, every event can be predicted with certainty.
A hard real time linux system is able to guarantee the determinism of the system. This does not mean that the system will be faster, but simply more predictable.

This course provides all the information necessary to understand the techniques available for transforming Linux into a Real Time system.

Real time linux with PREEMPT_RT allows using recent kernels that support these new features.

Real time linux with Xenomai, is based on a double I-Pipe kernel where applications are seen as kernel modules.
