From design-time concurrency to effective implementation parallelism: The multi-clock reactive case

Abstract

We have defined a full design flow starting from high-level domain specific languages (Simulink, SCADE, AADL, SysML, MARTE, SystemC) and going all the way to the generation of deterministic concurrent (multi-threaded) executable code for (distributed) simulation or implementation. Based on the theory of weakly endochronous systems, our flow allows the automatic detection of potential parallelism in the functional specification, which is then used to allow the generation of concurrent (multi-thread) code for parallel, possibly distributed implementations.
