Design and Realization of Gigabit Ethernet Interface Based on FPGA

摘要

Nowadays gigabit Ethernet is widely used in the area of computer and industry communication. In order to resolve the bandwidth of data transfer in high-speed data acquisition system, this paper introduces design principles and implementation methods of gigabit Ethernet interface based on FPGA. The physical layer hardware realization and the MAC layer realization are described in detail. At last, it presents the simulation through ISE simulator and validation on the hardware platform. The results show that the data transfer speed can reach lGbps and the design is very valuable in highspeed data acquisition system and software radio system.
