Hello,
To cut to the core, RTAI is basically an interrupt dispatcher that traps
interrupts and re-routes them up either through the RTAI (realtime)
modules, or for non realtime tasks back to the Linux kernel. RTAI also
provides an API for realtime functions, and floating point operations.
The gener
Yes,
in some words:
RTAI is much faster, but relies on the kernel you have, so it is much
more complicated to be included in software parts.
It is mostly needed only for very high speed applications
PREEMPT-RT is a a little bit slower than RTAI, but can be implemented in
software much easier,
Do anybode know the difference between RTAI and PREEMPT-rt?
