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 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 rtlinux_sigaction system calls.
