摘要
随着网络的日益普及,将嵌入式系统接入网络的想法也变得更加现实。介绍一种基于MicroBlaze处理器的嵌入式Web服务器的设计方法。系统在Virtex4系列LX25芯片上,采用软核处理器MicroBlaze配置核心处理器。MicroBlaze软内核是一种针对Xilinx的FPGA器件而优化的功能强大的标准32位RISC处理器。网络协议采用Xilnet,这是Xilinx公司专门针对Xilinx嵌入式系统应用而设计的网络通信协议,接口芯片使用LAN91C111。基于MicroBlaze的嵌入式Web服务器能够达到预期的效果,用户可以通过IE浏览器浏览存储在DDR SDRAM芯片中的网页,由于CPU本身是以软核的方式实现,其功能可根据需要进行定制,非常灵活。该Web服务器基于HTTP协议,采用TCP/IP套接字编程技术实现,能够实现对工业现场的数据采集、远程监控以及信息的交互。
With the development of Internet, the idea of merging embedded system into the network becomes more reliable. This paper introduces a design way of embedded Web server that based on the MicroBlaze. The system used soft core MicroBlaze to configure it on the LX25 chip. MicroBlaze is a standard RISC processor which has stronger optimized function and is specific towards Xilinx FPGA devices, Net protocol adopted Xilnet which is designed for Xilinx embedded system＇s application. Interface chip is LAN91C111. The system described in this article can reach the expected affect and users can browse the net in the SDRAM through IE, Due to the soft core implement way,it can be customized according to your own need and very flexible. The web server is implemented by TCP/IP Socket program technology and based on HTTP protocol, It can complete data acquisition,remote surveillance and imformation interaction.
