NAME
RTLinux -- RealTime Linux
RTLinux
RTLinux (RealTimeLinux) is a simple hard real time operating system
that runs Linux as its lowest priority thread. RTLinux follows the
POSIX PSE51 profile in which the realtime operating system looks some-
thing like a single POSIX process, with applications as signal handlers
and threads. The Linux thread provides access to all the services of a
POSIX PSE54 operating system so that the hard realtime part can remain
simple and fast. Programming in RTLinux is relatively straightforward:
RTLinux programs are generally written as loadable kernel modules and
use the pthreads API. Realtime components use signals, rt-fifos, and
shared memory to communicate with Linux kernel and user programs.
RTLinux also offers optional user-mode access to realtime facilities
via the rtlinux_sigaction system calls.
