基于NiosⅡ的嵌入式Web服务器设计与实现

Design and Implementation of Embedded Web Server Based on NiosⅡ

介绍了嵌入式设备的特点和发展需求,讨论了在其上应用嵌入式Web服务器的方法及设计思想。结合NiosⅡ的优点,在Altera公司的FPGA上实现了嵌入式Web服务器模块,提出并实现了基于C语言的动态HTML页面预处理的服务器应用接口程序方案。实验表明,该系统占用资源小,实时性强,能满足嵌入式Web服务器的交互需求。

The features and developmental needs of embedded devices are presented.The approaches and designing idea of using embedded Web server on embedded devices are discussed.Combining the NiosⅡ＇s advantage,the embedded Web server module is implemented on Altera＇s FPGA.The scheme,named dynamic HTML-page-preprocess,which is based on C Language,of application interface routine for embedded Web server is proposed and implemented.Experimental results show that the system takes up little resource,has strong real-time performance and can meet interactive request of embedded Web server.
