RTAI stands for Realtime Linux Application Interface for Linux - which lets you write applications with strict timing constraints for Linux. Like Linux itself the RTAI software is a community effort.RTAI supports several architectures:
- x86 (with and without FPU and TSC)
- PowerPC
- ARM (StrongARM; ARM7: clps711x-family, Cirrus Logic EP7xxx, CS89712, PXA25x)
- MIPS
RTAI provides deterministic response to interrupts, POSIX compliant and native RTAI realtime tasks.
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
The latest version of RTAI uses Adeos, providing additional abstraction and much lessened dependencies on the 'patched' operating system. Use of Adeos also frees RTAI from patent restrictions caused by RTLinux project.
