The Design And Implementation Of Embedded Web Server Based On FPGA

With the development of embedded systems, a variety of embedded devices has penetrated into people’s work and life in all aspects. Based on the rapid development of information network, a variety of embedded devices are also need the use of the Internet to send the information quickly. The client and server successfully exchange information through a web browser, while embedded devices connected to the Internet. Is particularly important in view of the research and development of information exchange urgency, embedded Web server will also because a trend for the future development of Internet.The system designed an embedded Web server based on FPGA, and got a fractal generation can be controlled through a web page, while the correct Mandelbrot or Julia fractal images displayed in the FPGA’s TFT LCD. In this paper, the SOPC system of the TFT controller and the embedded Web server was built on the Xilinx’s Spartan-3a FPGA, ISE and EDK. For the embedded Web server, Xilnet, Xilmfs and TCP/IP’s Socket have been used smoothly, and when input the type and parameter via a web page can get the correct Mandelbrot or Julia fractal.In the specific design, the SPI controller and tft enable just be designed to configure the TFT’s parameter and coordinate the timing of Web and TFT IP cores. Completed the testing, the expected Mandelbrot or Julia fractal images can be got in the LCD form the Web’s message of the type and parameter. The testing results show that the design and development of the embedded Web server correctly received and processed the request from client, and successfully returned the correct fractal images.The subject is effective in solving the problem that the need of embedded system in real-time network applications. At the same time, a kind of embedded Web server is proposed, and on the basis of application requirements. The results will be embedded on the Internet provide a strong evidence, and provide strong technical support for the realization of embedded devices, remote network monitoring, control, diagnostics and maintenance.
