RTAI stands for Real-Time Application Interface. It is a real-time extension for the Linux kernel - which allows you to write Linux hosted applications with strict timing constraints.
•RTAI 3.2 on a Linux 2.4.37.x kernel is supported for ARM 7300
•RTAI 3.6, 3.7.x and 3.8.x, 3.9.x are supported on the corresponding Linux 2.6 kernels
RTAI supports several architectures:
•x86 (with and without floating point unit (FPU) and timestamp counter (TSC) and on many multi-core CPUs)
•ARM (StrongARM; ARM7: clps711x-family, Cirrus Logic EP7xxx, CS89712, PXA25x, ARM9: Cirrus Logic EP93xx, Atmel AT91SAM, ARM Cortex)
•Like Linux itself the RTAI extension is a community effort. More information on RTAI can be found at: http://www.rtai.org.
•Contact Controllab Products for more information about using 20-sim 4C and RTAI on your own targets.
