About RTAI

Are you...

  • Tired of expensive realtime operating systems?
  • Looking for deterministic response to interrupts?
  • Working with POSIX compliant or native RTAI realtime tasks?
  • Searching for friendly community support?
  • All that ontop of a general purpose operating system with penguins inside?


Then RTAI might be the realtime extension of your choice! The Realtime Application Interface consists mainly of two parts:

A patch to the Linux kernel which introduces a hardware abstraction layer
A broad variety of services which make realtime programmers' lifes easier

RTAI is a true community project. Just download and try it out - the developers are looking forward to your comments, ideas and other help to make RTAI one of the best realtime extensions available!
