The Research And Develop Of Embedded Internet System Based On X86

Currently all sorts of intellectual electronic devices will access internet urgently, with the cmputer, communication network and internet technologies develop fast and the embedded systems permeate into human's life quickly.That determines the origination and development of the embedded internet technology.At first,the thesis sumarrize the occurrence, development and application prospects of the embedded Internet. Then according to the introductions of the basic principle of the embedded Internet and the comparision of several domestic or foreign solutions to it, the paper puts forward a solution to build the embedded network platform based on the advanced X86 microcontroller. Immediately the paper describes detaily the design principle and the hardware structure of the whole system, and pay much attention to the software and hardware design about the 10M/100M Ethernet network interface based on the PCI bus. Finally describes the design and test of the TCP/IP protocol stack in the system, which proves that such a scheme is workable . From the paper, it can be concluded that it is necessary to make many intellectual electronic equipments access the Internet in the new era, with the development of the computer, communication and the network technique, and the embedded network platform based on the advanced X86 microcontroller has the characteristics of simplity, clarity and high-adaptability in the applications, it can be widely applied to many industrial fields such as power automation, communication terminal , monitoring and measuring system on line , embedded Web, network protocol transformation, intellectual instruments etc.
