Abstract [en]

We study a graph-based real-time task model in which inter-task synchronization can be specified through a rendezvous mechanism. Previously, efficient methods have been proposed for timing analysis of the corresponding task sets. In this paper, we first formally specify an operational semantics for the model. Next, we describe a method for Ada code generation for a set of such task graphs. We also specify extensions of the approach to cover a notion of broadcasting, as well as global inter-release separation time of real-time jobs. We have implemented the proposed method in a graphical tool which facilitates a model-based design and implementation of real-time software.
