RTLinux

RTLinux (or Real-Time Linux) is an extension of Linux to a real-time operating system, which was originally developed by Victor Yodaiken at the New Mexico Institute of Mining and Technology. Wind River Systems acquired FSMLabs technology in February 2007 and now makes a version available as Wind River Real-Time Core for Wind River Linux.

RTLinux supports hard real-time (deterministic) operation through interrupt control between the hardware and the operating system. Interrupts needed for deterministic processing are processed by the real-time core, while other interrupts are forwarded to the non-real time operating system. The operating system (Linux) runs as a low priority thread. First-In-First-Out pipes (FIFOs) or shared memory can be used to share data between the operating system and the real-time core.
