Designing dynamic reconfiguration for distributed real time embedded systems

An embedded software system is reconfigurable when it can modify its behavior or its architecture. The reconfigurations are launched according to the evolution of context requirements and the variation of execution environment constraints. The constant growth of the complexity in embedded systems makes the reconfiguration more important and more difficult to achieve. The challenges concern as much the design model level as the runtime support level. Here we focus our attention on design model level. In our work, we aim at providing an automated development process from model to implementation for the dynamic software part of these systems. The contributions of this paper are twofold. First, we use the notion of structure to capture configurations instead of defining each of them. Second, we propose a set of tools to be used in a model driven approach to specify and configure reconfigurable software architectures of distributed real time embedded (DRE) systems.
