Real-time synchronization between hard and soft tasks in RT-Linux
Proceedings Sixth International Conference on Real-Time Computing Systems and Applications. RTCSA'99 (Cat. No.PR00306), 2003This paper presents the experience in adding a synchronization protocol to our architecture for flexible hard real-time systems. The architecture combines mandatory and optional components in a two-level tasking model. Mandatory and optional components share resources, and therefore synchronization is needed in order to maintain both the logical ...

Multi-Axis EDM CNC System Based on RT-Linux
Key Engineering Materials, 2009In order to manufacture geometrically complex or hard material parts, a new kind of multi-axis electro-discharge machining (EDM) computer numerical control (CNC) system, which is based on RT-Linux platform, was presented. Dual-kernel structure of System is adopted: Linux and RT-Linux are used to realize Time-sharing tasks and Real-time tasks separately.

An Adaptive Value-Based Scheduler and Its RT-Linux Implementation
2002In dynamic real-time systems, value-based scheduling aims to achieve graceful degradation during overloads, in addition to maintaining a high schedulability during normal and underloads. The objective of this paper is twofold: (1) to propose an adaptive value-based scheduler for multiprocessor real-time systems aimed at maintaining a high system value ...

Using RT-Linux for Developing Real-time Embedded Systems
IFAC Proceedings Volumes, 2001ABSTRACT Linux has been effectively used as a reliable operating system in workstations and servers. However, the interest for using it in embedded systems has grown recently, due to the easiness for customizing it and the availability of the source code. This paper describes the experience of customizing RT-Linux for its use in an embedded real-time

Experiences using RT-Linux to implement a controller for a high speed magnetic bearing system
Proceedings of the Fifth IEEE Real-Time Technology and Applications Symposium, 2003Control systems based on embedded DSP boards often require specialized programming and development tools, lack interoperability with standardized architectures and tools, lack flexibility when computational requirements change, and are often relatively expensive.

RT-Linux Based Hard Real-Time Software Architecture for Unmanned Autonomous Helicopters
11th IEEE International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA'05), 2006The UAV (unmanned aerial vehicle) performs various kinds of missions while performing autonomous flight navigation. In order to realize all functionalities of the UAV, the software part becomes a very complex hard real-time system because some hard real-time tasks, soft real-time tasks and non-real-time tasks are concurrently working together under a ...
