OpenDF - A Dataflow Toolset for Reconfigurable Hardware and Multicore Systems

Marco Mattavelli

This paper presents the OpenDF framework and recalls that dataflow programming was once invented to address the problem of parallel computing. We discuss the problems with an imperative style, von Neumann programs, and present what we believe are the advan ...
