In this paper, we propose a network crossbar implementation using partial reconfiguration of an FPGA in a multi-FPGA cluster computing system.With a proposed framework, inter-FPGA network routing can be changed by reconfiguring the crossbar module by a partial reconfiguration mechanism.The purpose of this paper is to compare ordinary crossbar circuits and partial reconfiguration crossbar circuits, in terms of resource usage and the maximum operating frequency.As a result, by using partial reconfiguration, the maximum operating frequency is improved by 1.6 times while reducing required ALM resources by 13%, a proper bus sizes for a crossbar are selected.
