英文摘要：
Based on the background of the application of DS80C400 in the embedded intelligent network-bridge, the basic request of embedded system used in hardware design is analyzed,and the hardware plan of embedded intelligent network bridge is given. The unique and powerful function DS80C400 ROM internal core is studied, including the load module initialization of network protocol stack, memory management, the process of scheduling and so on; the task of TINI OS built-in real-time operating system is to create, hang and delete; Inputting and outputting data format and file system library functions. The way to realize embedded WEB is given based on SOCKET. Based on the file system and embedded web page the way pointer array of methods to achieve and core division of real-time task, the software program of DS80C400 ROM Internal core intelligent network-bridge for the task of scheduling synchronization is realized. The practical application shows that based on the practical application of proven DS80C400 development of embedded network system design to meet the actual needs of project＇s technical specifications, has greatly enhanced the efficiency of development and stability of the system.
