The Research Of Ethernet Technology Based On DSP And Implementation Of The Terminal

Based on the excellent performance of DSP, this thesis introduces the embedded system cored with DSP into computer network. This application system gradually takes the place of traditional computer's net application and becomes the main force of Internet development in the future.This thesis begins with the introduction of some kernel protocols of TCP/IP stack and has realized the embedded termina with Ethernet protocols. Based on thorough analyzing the net protocols, such as IP, UDP, ARP, and so on, we simplify them. The detailed implementation of the simplifed protocols is presented. The embedded DSP Ethernet terminal system's software/hardware scheme, called as Ethernet Over DSP, is proposed. We present the scheme's hardware-circuit principles and software-realization processes in detail. At the same time, aiming at the PC's data exchange with the Ethernet terminal, this thesis analyzes and expatiates socket mechanism, presents PC software realization methods and an expandable program frame.In the last place, we solve the problem of seamless-connection between the embedded system cored with DSP and Internet, and share information problem. The new field for DSP's network application is explored.
