A study on Inter-Board Data Transmission of FPGA Cluster

Abstract

In recent years, using field-programmable gate arrays (FPGAs) to improve computer performance has attracted attention, and configuration methods such as FPGA clusters, which are one of the ways they can be implemented, have been extensively researched and used. The router circuit of the FPGA cluster does not have a specific production method, and it has led to an increase in research and development. In view of these circumstances, general purpose connection networks for FPGA clusters are being studied. However, many methods have unique specifications in the interconnection network. Therefore, we aim to develop an interconnection network with high versatility and extensibility by making it according to the specifications of Qsys for Intel® FPGA. We aim to prepare a router circuit for constructing an interconnection network and conducted an operation test. It operated normally up to the operating frequency of 150 MHz.
