From Wikipedia, the free encyclopedia
RTLinux or RTCore is a hard realtime RTOS microkernel that runs the entire Linux operating system as a fully preemptable process.
It was developed by Victor Yodaiken at the New Mexico Institute of Mining and Technology and his company, FSMLabs. 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 Linux, which runs at a lower priority than realtime threads. Linux drivers handle almost all I/O. First-In-First-Out pipes (FIFOs) or shared memory can be used to share data between the operating system and RTCore.
