A higher level system communication model for object-oriented specification and design of embedded systems

The design starting point for current embedded systems design is getting higher and higher on the abstraction level scale in order to meet the challenge of the increasing design gap. Up to now the state-of-the-art tools and methods have used as a highest abstraction of communication for the send-receive over a channel, e.g. as in SDL and COSSAP. We introduce a novel higher level communication mechanism for system-level specification which has features supporting object-oriented descriptions and client-server type communication modelling as in CORBA. The communication primitives have been implemented as extensions to System-C, and simulation experiments have been performed.
