Timing analysis of the PREEMPT RT Linux kernel

Software: Practice and Experience, 2015
SummaryIn the theory of real‐time scheduling, tasks are described by mathematical variables, which are used in analytical models in order to prove schedulability of the system. On real‐time Linux, tasks are computer programs, and Linux developers try to lower the latencies caused by the Linux kernel, trying to achieve faster response for the highest ...

Developing CAN based networks on RT-Linux

ETFA 2001. 8th International Conference on Emerging Technologies and Factory Automation. Proceedings (Cat. No.01TH8597), 2002
This paper describes the experience of customizing RT-Linux for its use in embedded real-time control. It describes the system configuration and the issues involved in minimizing Linux for a small embedded system. It introduces the concept of file system profiles to deal with this minimization.

TASK DECOMPOSITION IMPLEMENTATION IN RT-LINUX

IFAC Proceedings Volumes, 2002
Abstract Control applications require defining several parallel activities to model the environment. Periodic tasks model the activities to be executed at periodic instants of time. While the process of control design is focused on obtaining the regulator, later on translated into an algorithm, the software design is focused on producing pieces of ...

An evaluation of the POSIX trace standard implemented in RT-linux

2001 IEEE International Symposium on Performance Analysis of Systems and Software. ISPASS., 2005
As real-time applications become more complex, the availability of event tracing mechanisms becomes more important in order to perform run-time monitoring. The recent approved standard POSIX 1003.Iq defines a common application interface for trace management.

Research on reliability and real-time of on-board computer based on RT-Linux

2021 IEEE 5th Information Technology,Networking,Electronic and Automation Control Conference (ITNEC), 2021
Reliability and real-time are extremely important indicators in the aerospace field. With the increasing complexity of nano satellite missions, research on the reliability and real-time of on-board computers has become very important. This paper uses AM5748 chip manufactured by Texas Instruments as the processor, which is equipped with RT-Linux for the

RTOC: A Rt-Linux Based Open Robot Controller

2006 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006
An open robot control system pursues easy extension, flexible reconfiguration, facile portability and jointless interoperation. Therefore, the system elements from multi-disciplinary areas can be integrated and reconfigured easily in such a system. Also the system modules can be ported flexibly.

Experiences in implementing an energy-driven task scheduler in RT-Linux

Proceedings. Eighth IEEE Real-Time and Embedded Technology and Applications Symposium, 2003
Dynamic voltage scaling (DVS) is being increasingly used for power management in embedded systems. Energy is a scarce resource in embedded real-time systems and energy consumption must be carefully balanced against real-time responsiveness. We describe our experiences in implementing an energy driven task scheduler in RT-Linux.

A MINIMAL RT-LINUX EMBEDDED SYSTEM FOR CONTROL APPLICATIONS.

IFAC Proceedings Volumes, 2002
Abstract The use of embedded PC in control systems is increasing. There exist a significant number of real-time operating systems but RT-Linux provides several advantages over most of them. RT-Linux shares the processor with standard Linux allowing to run accurately timed applications to perform data acquisition and control systems with Linux ...

RT-Linux Priority Reversal and Priority Inheritance Mechanisms

2013 Fifth International Conference on Measuring Technology and Mechatronics Automation, 2013
RT-Linux is a kind of embedded Linux, its real time performance is relative high among numerous kind of embedded Linux, but it requires the operation system have high real time performance and using priority inheritance protocol to solve the priority reverse problem in RT-Linux. In order to trace the system roundly, a kernel trace tool is designed, and

A Predictable Module for Sharing Memory in RT-LINUX 1

IFAC Proceedings Volumes, 1998
Abstract Recently, RT-Linux has emerged as a promising approach for developing hard real-time systems. RT-Linux is a real-time executive placed underneath the Linux kernel. This executive basically provides a support for running real-time tasks at the kernel level and turns the whole Linux into one of these tasks.
