>RTLinux (RealTimeLinux) is a simple <I
CLASS="EMPHASIS"
>hard real time</I
> operating system
that runs Linux as its lowest priority thread. RTLinux follows the POSIX PSE51 profile
in which the realtime operating system looks something 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 <TT

>rtlinux_sigaction</TT
> system calls. </P
