Design and Application of Internet Terminal Based on ARM

Through analyzing TCP/IP protocol and character of embedded system,a design of Internet terminal based on ARM is presented,and the key technologies of realization of TCP/IP protocol are discussed.A set of reduced and practical TCP/IP protocol is designed,and introduces the process of realizing for every protocol-layer in detail.The operating system of μC/OSII is transplanted to the system,hardware is based on ARM microcontroller,it realizes embedded system access network,finally applies this protocol stack to application in industry′s Ethernet.It provides a feasible method for exploiture of embedded network system.
