LinuxDevices: Running Real-time Linux on the Axis ETRAX System-on-chip

"Real-time, embedded systems and Linux are commonly used words in these days. The thesis on which this article is based looks deeper into the possibility of turning Linux into a real-time operating system. Particularly, it investigates available hard real-time solutions for Linux, but also looks into the soft variants for completeness.

"RTAI is selected as a suitable solution for Axis and is ported to the ETRAX 100LX, an Axis-developed system-on-chip processor designed with networking and embedded systems in mind. A large number of performance tests are conducted during the evaluation to make sure that the implementation meets the demands of a real-time operating system.

"The evaluation shows that RTAI provides good real-time performance, especially when compared to standard Linux..."
