42: programmable models of computation for a component-based approach to heterogeneous embedded systems

Abstract

Every notion of a component for the development of embedded systems has to take heterogeneity into account: components may be hardware or software or OS, synchronous or asynchronous, deterministic or not, detailed w.r.t. time or not, detailed w.r.t. data or not, etc. A lot of approaches, following Ptolemy, propose to define several 'Models of Computation and Communication' (MoCCs) to deal with heterogeneity, and a framework in which they can be combined hierarchically.
