ART Linux a Real-Time extension to Linux. It is inspired by RT-Linux. ART-Linux allows you to re-use existing Linux device drivers and application programs and easily achieve proper real time performance. Axis Linux/ETRAX Ethernet and Token Ring controller from AXis: based on the 2.0 Linux kernel. Using the uClinux NO_MM patches. Designed to meet demands for low cost, easy implementation and superior network performance, the ETRAX 100 is Axis' fifth-generation optimized system-on-a-chip solution for connecting peripherals on the network KURT The KU Real-Time Linux is a real-time system in which, in addition to the logical correctness of results, the timeliness is also of importance. L4Linux Linux on the L4 µ-Kernel Linux PA-RISC the primarily purpose of this project is to provide a native port of Linux to the PA-RISC architecture, which will be merged into the mainstream kernel tree and into commercial distributions. The target is to have Linux running on the HP 9000 family of UNIX servers Real-Time Linux an extension to Linux that handles time-critical tasks. RT-Linux shares a PC between a small hard-real-time kernel and standard Linux, so that the PC can be used for applications like data acquisition, control, and robotics while still serving as a standard Linux workstation
