Abstract：In order to solve the problems of the traditional embedded Ethernet system,such as low data transmission rate,hardware cannot be upgraded,poor real-time and universality etc,the Ethernet controller design scheme based on Altera Cyclone series FPGA with Nios II CPU was proposed.The design aimed at Ethernet protocal using the Quartus II and Nios II IDE as the development tools for reconfiguration of the hardware in order to reduce the cost and improve the system integration.The SOPC technology was used to construct the embedded network hardware platform and based on μC/OS-II to achieve the migration of Ni-cheStack TCP/IP and compiling of the top application.The system test results showed that the design met the requirement of the Ethernet communication rate at the data rate of about 400 Mb/s,and could be flexi-ble configurated according to actual situation.
