Gigabit Ethernet Data Transfer Based on FPGA

Abstract

With the development of integrated module, FPGA chip becomes more and more popular. Except for some special application, FPGA devices need an effective mechanism to receive and send data. The general FPGA is suitable for the connection technology of PCI Express. We always use it as a communication scheme between PC and FPGA board. However, the shortcoming is that the PCI Express scheme is expensive. Theoretically, we propose a very effective communication structure, which with core of UDP/IP is a point to point structure. We found that it can establish stable communication connection between PC and FPGA through combining IPV4 with UDP protocol by hardware. Through a simple way to calculate the frame header and to check IPv4 (supposing every computing model based on FPGA), we use less resource to achieve the establishment of a communication connection between PC and FPGA.
