Reuse-oriented design of embedded systems

The paper describes an object oriented model and a reuse oriented methodology for the co-design of embedded computer systems. Our approach is based on a hierarchy of classes which describes all possible specifications of systems of a certain domain, the behavior of hardware and software components, and the target architectures. The content of this knowledge base (reusable, formalized descriptions) is determined by the analysis of known systems. We present solutions for a specification methodology, the modeling of heterogeneous systems by task graphs, and the mapping process from specified requirements down to hard- or software components in a target architecture. This approach is illustrated by functions of the domain of robot controls.
