Design Of Embedded Dynamic Web Server Based On UClinux

With the development at full speed in the microelectric technique and computer technology, the embedded systems are widely used. Because it has small space, low power dissipation and powerful performance, the embedded system has already applied to such fields as military national defence, industrial control and intellectual home appliances and so on. Meanwhile, more and more embedded equipments require using web server in it in order to visit them through Internet, and make some simple control. How to realize the industrial equipment or the intelligent electrical appliances control through Internet become hot spot. In this case, that the embedded web server was realized become the key. Under this background, work was done mainly in this article for the embedded Web server as following:The hardware platform based on S3C44B0 was designed. And built Web server hardware by the basic system auxiliary equipment, ethernet controller, SDRAM, FLASH and so on.The key technologies of uClinux to apply in the embedded system was discussed, including the core composition, the memory management, the multi-process management, the executiable document format, the core load way and so on.The Bootloader architecture was studied, Bootloader operation pattern and S3C44B0 re-map mechanism.were analyzed.The embedded Web server was realized .and it can support the dynamic Web function. the embedded Web server from aspects of HTTP protocol, CGI technology, were analyzed and so on.In this paper, the application of S3C44B0X based on ARM7TDMI architecture was study, and the embedded web server which is constructed on B/S network mode. was implemented. The server is based on S3C44B0X, and the uClinux which schedules the tasks and build the boa network server is ported to S3C44B0X. It is low cost, simple design and easy to upgrade. and an embedded Web Server with good dynamic Web page function. This provides with a higher practice and research value in the field of studying embedded system. The embedded system has the characters of low cost and high efficiency. At least, a sum-up and prospect of some other usage of Linux embedded system are given.
