A Compiler Intermediate Representation for Reconfigurable Fabrics

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
