Application of FPGA in data receive storage and transmission

In order to meet the future requirements of the rapid development of embedded system,a method based on Xilinx FPGA system on a programmable chip(SOPC) technology is proposed to achieve CF card(compact flash) storage of large amounts of data and the data transmission using light weight IP(LwIP).First,the hardware structure of the entire system,Xilinx SOPC development tools,processes and use of key technologies are introduced.On this basis,a SOPC platform is built using the Xilinx embedded development kit,based on intellectual property(IP) core provided by Xilinx.By using CF card,LwIP protocol in software design,the driver and application program development is realized,and by testing and communicating with the host computer,the feasibility and effectiveness of the design is verified.
