The Design And Implementation Of Thernet Controller Technology Based On FPGA

With the network, further development of information technology and equipment to further strengthen intelligence, single-function device functions are no longer uniform, the structure becomes more complex, more high level of integration to achieve more and more and more functions humanity. With the emergence of SOC products market, embedded technology in the industry are widely used around the world. Embedded systems product development and applications have become information technology to stimulate industrialization, promote the development of the new information economy growth. Along with electronic equipment, household appliances, and other entertainment activities to promote the countryside, Internet rapid development of intelligent consumer entertainment product development, embedded systems will bring more convenience to everyday life by people of all ages, its development will be more more business attention.The resulting embedded system is connected to the Internet, according to the background paper, designed and implemented FPGA-based Ethernet controller for embedded system provides the interface to connect Internet, combined with the provided driver, you can implementation sending and receiving data.Based on the analysis of the Ethernet data frame format, the data sending and receiving process may anticipate the problems and how to avoid such problems and how to deal with after problems have been studied to design and implement a Ethernet controller framework. And the design with Quartus II 9.1 development software for design, implementation, simulation experiment. Experimental results show that the design of the Ethernet controller can control the data receiving, sending, it also has some common problems for the processing power, if they could send the data validation process, for error handling.
