Abstract

Pascal Aubry, Paul LeGuernic, and Sylvain MachardSIGNAL, a synchronous and data-flow oriented language, allows the user to design safe real-time applications. Its compiler uses a single formalism called "Synchronized Data-Flow Graphs" (SDFGs) all along the conception chain from specification to proof and verification. We show how this formalism can be kept on until distributed code generation. The implementation described here, called synchronous distribution, respects the observational semantics of SIGNAL. We finally show the limits of SDFGs and conclude on the necessity of another model describing dynamic behaviors of distributed executions.
