An intermediate representation (IR) is a central structure around which tools such as compilers and synthesis tools are built. In this paper we propose such an IR specifically designed for reconfigurable fabrics: CIRRF (Compiler Intermediate Representation for Reconfigurable Fabrics). We describe an initial implementation of CIRRF as part of the ROCCC compiler for translating C code to VHDL. A case study shows that our IR set is a solid foundation to generate high-performance hardware.
