Reuse-oriented design of embedded systems

This 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 hard- and software-components, and the targer-architectures. The content of this knowledge base (re-usable, formalized descriprions) 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.
