A component-based model integrated framework for embedded software

Abstract

The development of distributed, concurrent software in embedded systems is becoming increasingly complex and error-prone. Model-based integration of reusable components is advocated as the method of choice. To this end, we propose a framework to support component-based model integration, hierarchical functionality composition, and reconfiguration of systems with continuous and discrete dynamics. In this framework, components are designed and used as building blocks for integration, each of which is modeled with abstract ports, reactions, and communication schemes. It uses hierarchical composition to hide the implementation details of components, and keeps the components at the same level of hierarchy interacting under a well-defined model of computation. Code generation takes the design decisions down to the final running system. Within this framework, embedded software can be constructed by selecting and then connecting components in a functionality repository, specifying models and transforming them to executable codes. © Springer-Verlag Berlin Heidelberg 2005.
