RTLinux

RTLinux was developed by Wind River Systems. Wind River has discontinued the Wind River Real-Time Core product line in 2011, effectively ending commercial support for the RTLinux product. RTLinux was a real-time operating system microkernel that ran the entire Linux operating system as a fully preemptive process. The hard real-time property made it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.
