FiC (Flow-in-Cloud) is a multi-FPGA system to realize a monolithic large FPGA image with multiple cost-efficient mid-range FPGAs connected with flexible and high bandwidth interconnection network. The FPGA is used as both for computational resource and the network circuit switch, and separating FPGA regions by partial reconfiguration (PR) design technique. In this paper, we will introduce the FPGA design methodology with the PR technique for the FiC system. Evaluation result shows that the proposed design methodology reduces design and configuration time, and it enables to replace the region for computation without stopping the network running on the same FPGA.
