Modelling and Code Generation for Real-Time Embedded Systems with UML-RT and Papyrus-RT

This paper discusses the Model-Driven Engineering (MDE) of real-time embedded (RTE) systems with soft real-time constraints using UML for Real-Time (UML-RT) and Papyrus-RT. UML-RT is a profile of UML specifically designed for RTE systems. It has a long, successful track record of application and tool support via, e.g., IBM Rational RoseRT, IBM RSA-RTE, and now Papyrus-RT. Papyrus-RT is an Eclipse-based, open-source modelling development environment for UML-RT systems. It allows the generation of complete, executable code from models and advances the state-of-art via support for model representation with mixed graphical/textual notations and an extensible code generator. This paper introduces the central modelling concepts of UML-RT and features of Papyrus-RT. It also presents some advanced features of Papyrus-RT such as import capabilities, mixed graphical/textual modelling, and incremental code generation.
