RTAI - Real Time Application Interface Official Website

This is the homepage of RTAI - the RealTime Application Interface for Linux - which lets you write applications with strict timing constraints for your favourite operating system. Like Linux itself this software is a community effort. If you are interested in what it does just join our mailing list and help our team!

RTAI supports several architectures:

  • x86 (with and without FPU and TSC)
  • x86_64
  • PowerPC
  • ARM (StrongARM; ARM7: clps711x-family, Cirrus Logic EP7xxx, CS89712, PXA25x)
  • m68k (supporting both MMU and NOMMU cpus)

The RTAI distribution includes RTAI-Lab, a tool chain to convert block diagrams into RTAI executables and to monitor their operation on various targets.
