Real-time application interface (RTAI) is a
.RTAI consists mainly of two parts: an Adeos-based patch to the Linux kernel which introduces a hardware abstraction layer, and a broad variety of services which make lives of real-time programmers easier. RTAI versions over 3.0 use an Adeos kernel patch, slightly modified in the x86 architecture case, providing additional abstraction and much lessened dependencies on the "patched" operating system. Adeos is a kernel patch comprising an Interrupt Pipeline where different operating system domains register interrupt handlers. This way, RTAI can transparently take over interrupts while leaving the processing of all others to Linux. Use of Adeos also frees RTAI from patent restrictions caused by RTLinux project.
RTAI-XML
RTAI-XML is a server component of RTAI, implementing a service-oriented way to design and develop real-time (RT) control applications.
This project was born to fulfill the needs of a university group, mainly focused to have a flexible platform for learning control systems design, allowing the students to test their programs remotely, over the Internet. Leaving the first wishful thinking and going to the real implementation gave rise to the alpha version of RTAI-XML, that showed the potential impact of the basic idea of a net separation of hard and soft real-time tasks in the programmation logic. What was necessary to assure that students could not crash the RT process, is now becoming a new RTAI paradigm.
RTAI-XML consists of a server component waiting for incoming calls on a box where a real-time process, the Target, is running (or ready to). A generic client program, the Host, can reach the server through the
The RTAI-XML section of this site presents the details of the implementation. The general architecture is revised, in order to focus the three key components, the Server, the Server-Target interface and the Server-Host communication. The Applications section contains some examples of control systems based on RTAI-XML and the References section contains hints and links for further readings on this topic.
