QUKU: A Coarse Grained Paradigm for FPGAs

To fill the gap between increasing demand for reconfigurability and performance efficiency, CGRAs are seen to be an emerging platform. The advantage lies in quick dynamic reconfiguration and power efficiency. Despite having these advantages they have failed to show their mark. This paper describes the QUKU architecture, which uses a coarse-grained dynamically reconfigurable PE array (CGRA) overlaid on an FPGA. The low-speed reconfigurability of the FPGA is used to optimize the CGRA for different applications, whilst the high-speed CGRA reconfiguration is used within an application for operator re-use
