DFGenTool: A Dataflow Graph Generation Tool for Coarse Grain Reconfigurable Architectures
2017
In this paper, DFGenTool, a dataflow graph (DFG) generation tool, is presented, which converts loops in a sequential program given in a high-level language such as C, into a DFG. DFGenTool adapts DFGs for mapping to Coarse Grain Reconfigurable Architectures (CGRA) to enable a variety of CGRA implementations and compilers to be benchmarked against a standard set of DFGs. Several kernels have been converted and are presented in this paper as case studies. The output of DFGenTool is in DOT, a popular graph description standard which could be used with a variety of CGRA compilers. Furthermore, DFGenTool has been released as open-source.
