Mapping of concurrent object-oriented models to extended real-time task networks

For checking the temporal behaviour of embedded systems, real-time scheduling analysis based on abstract, formal models is a well-established method. A major difficulty for such analytical models in practical use-cases is the non-trivial representation of a real implementation model. To overcome this limitation we propose a formal mapping of a concurrent, object oriented, executable implementation model with explicit shared resources to a real-time task network with functional extensions. The mapping starts from a C++ subset and maps the functional behaviour based on externally observable synchronisation events. The proposed mapping allows to check the implementation model against functional and temporal requirements, like local and end to-end deadlines.
