Synchronous Modeling of Data Intensive Applications

In this report, we present the first results of a study on the modeling of data-intensive parallel applications following the synchronous approach. More precisely, we consider the Gaspard extension of Array-OL, which is dedicated to System-on-Chip codesign. We define an associated synchronous dataflow equational model that enables to address several design correctness issues (e.g. verification of frequency / latency constraints) using the formal tools and techniques provided by the synchronous technology. We particularly illustrate a synchronizability analysis using affine clock systems. Directions are drawn from these bases towards modeling hierarchical applications, and adding control automata involving verification
