RTLinux

From Wikipedia, the free encyclopedia

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. RTLinux was made available as a community supported free version, called RTLinux Free, as well as a commercial version, called RTLinux Pro. Wind River Systems acquired FSMLabs technology in February 2007 and now makes the technology 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.
