A Model of Computation for Real-Time Applications on Embedded Manycores

This paper presents a first work to bring a consistent Model of Computation (MoC) for real-time applications on embedded many-core systems. Embedded manycores have lots of constraints (power, heterogeneity, memory, etc.) but also lots of promises with regard to harness able applications, i.e. New kinds of applications that could fit embedded systems. Such a MoC would encompass both data movements in Manycore´s memories, determinism of execution, composability but also real-time requirements. We build our MoC on a well known base - CycloStatic Data Flow (CSDF) - for its desirable properties (i.e. Determinism and composability), and thank to several case-studies, we extend it to a superset, adding two special data processing filters which preserve these good properties and provide useful features for embedded computing.
