The document summarizes a presentation given at the Conference on Design and Architectures for Signal and Image Processing (DASIP) in 2011. It discusses the Multi-Dataflow Composer (MDC) tool, which automatically composes different functional units specified using dataflow models of computation onto a coarse-grained reconfigurable hardware template. The MDC aims to close the gap between complex multi-purpose hardware platforms and their software programming by leveraging dataflow models and runtime reconfiguration. It allows developing runtime reconfigurable multi-purpose systems from high-level dataflow descriptions.
