Design and realization of Gigabit Ethernet in embedded system

High-speed and stable transmission of mass data is often required for embedded systems. Gigabit Ethernet has the characteristics of low price,fast and long-distance transmission,so it is widely used in high-speed computer communication. The schematic design,hardware design and software driver of Gigabit Ethernet based on PowerPC are offered in this paper. The function design scheme of Gigabit Ethernet is proposed. The schematic design is universal and flexible,can meet the perfor-mance requirements of high-speed data transmission in embedded systems,and provide a perfect solution for high-speed Ether-net communication in embedded system.
