High-level synthesis of dynamic dataflow programs on heterogeneous MPSoC platforms

The growing complexity of digital signal processing applications make a compelling case the use of high-level design and synthesis methodologies for the implementation on programmable logic devices and embedded processors. Past research has shown that, for complex systems, raising the level of abstraction of design stages does not necessarily come at a penalty in terms of performance or resource requirements. Dataflow programs provide behavioral descriptions capable of expressing both sequential and parallel components of application algorithms and enable natural design abstractions, modularity, and portability. In this paper, an open source tool, implementing dataflow programs onto embedded heterogeneous platforms by means of high-level synthesis, software synthesis and interface synthesis is presented Experimental design results demonstrate the capability and the effectiveness of the tool for implementing a wide range of applications when combined with Vivado HLS.
