Model-Based Hardware Design based on Compatible Sets of Isomorphic Subgraphs Model-Based Hardware Design based on Compatible Sets of Isomorphic Subgraphs

Hardware applications in an industrial context often have tight area, latency and throughput requirements or a specific combination thereof. This paper presents a method to improve area and throughput figures for folded circuits generated during a model-based hardware design process. The method targets FPGA implementations and is based on the automatic combination of isomorphic subgraphs and the detailed consideration of pipelined primitive operations for folding core scheduling. In the course of a design space exploration, the user is provided with fine-grain control over the area/throughput trade-off.
