Background: Reconfigurable computing technologies offer the promise of substantial performance gains over traditional architectures via customising the topology of the underlying architecture to match the specific needs of a given application, even at run-time. Contemporary configurable architectures allow for the definition of architectures with functional and storage units that match in function, bit-width and control structures the specific needs of a given computation. The flexibility enabled by reconfiguration is also seen as a basic technique for overcoming transient failures in emerging device structures. The International Symposium on Applied Reconfigurable Computing (ARC) aims to bring together researchers and practitioners of reconfigurable computing with an emphasis on practical applications of this promising technology.
Title: A Framework for High Level Simulation and Optimisation of Coarse-Grained Reconfigurable Architectures
Abstract: High-level simulation tools are used for optimisation and design space exploration of digital circuits for a target Field Programmable Gate Array (FPGA) or Application Specific Integrated Circuit (ASIC) implementation. Compared to ASICs, FPGAs are slower and less power-efficient, but they are programmable, flexible and offer faster prototyping. One reason for the slow performance in FPGA is their finer granularity as they operate at bit-level. The possible solution is Coarse Grained Reconfigurable Architectures (CGRAs) that work at word-level. There already exists a myriad of CGRAs based on their architectural parameters. However, the CGRA research lacks in design automation since high-level simulation and optimisation tools targeted at CGRAs are nearly non-existent. In this paper, we propose a high-level simulation and optimisation framework for mesh-based homogeneous CGRAs. As expected, the results show that auto-generated homogeneous CGRAs consume 54% more resources when compared with academic FPGAs while providing around 63.3% faster mapping time.
