Abstract

In order to convert High Level Language (HLL) into hardware, a Control Dataflow Graph (CDFG) is a fundamental element to be used. Related to this, Dataflow Architecture, can be obtained directly from the CDFG. The ChipCflow project is described as a system to convert HLL into a dynamic dataflow graph to be executed in dynamic reconfigurable hardware, exploring the dynamic reconfiguration. The ChipCflow consists of various parts: the compiler to convert the C program into a dataflow graph; the operators and its instances; the tagged-token; and the matching data. In this paper, a C compiler to convert C into a dataflow graph and the graph implementation in VHDL is described. Some results are presented in order to show a proof-of-concept for the project.
