摘　　要：随着互联网技术的发展,在嵌入式设备上实现网络通信成为热门研究对象。介绍了基于TMS320DM642的嵌入式Web服务器的设计方法,相对于其他处理芯片,TMS320DM642具有更高的实时处理速度和丰富的软硬件资源,结合其自带的NDK网络开发工具在软件上可以快速地开发网络应用程序,降低了开发难度,缩短了开发周期。本设计利用嵌入式实时操作系统DSP/BIOS和NDK在DM642上开发多线程网络程序,实现了服务器的网络通信功能,同时借助通用网关接口技术(CGI)实现了客户端浏览器与服务器的数据交互,可通过网页对底层硬件进行实时控制。测试结果表明,服务器设计合理,运行稳定,可以实现高速数据传输以及网页远程操控底层硬件功能,在构造嵌入式Web服务器方面具有较高的应用价值。With the development of Internet technology, network communication in embedded devices has become a popular research object. This paper presents a design of embedded Web server based on TMS320DM642. Relative to other processing chip, TMS320DM642 has higher real-time processing speeds and richer resources on hardware and software,combined with its web development tool NDK can develop network application software rapidly, reducing the development effort and shorten the development cycle. The design uses the embedded real-time operating system DSP/ BIOS and NDK on DM642 to develop embedded web server and multithread network program, realize the function of communication with clients,at the same time, with the common gateway interface （CGI） technology to achieve the client and server data interaction. The final experiment results show that the server is well designed,and it can achieve highspeed data transmission as well as web remote manipulation of the underlying hardware function,has a high value in the construction of embedded web server.
