The Study And DSP Realization Of Embedded TCP/IP

Ethernet communication technology adoptting TCP/IP has interoperability, so it is becoming the study hotspot that Ethernet is applied in field controlling system such as electric automation system. In this paper, TCP/IP was studied and analyzed firstly and chosed while the real condition of embedded system is considered. And then the Ethernet interface is designed with DSP chip and network interface controller (NIC) chip. The system drive program was compileded after the analysis of the NIC's principle and inner register. The third, the auxiliary files was discussed which is demanded when the protocol program is designed with C language in DSP's development entironment, including header file and interrupt vectors file and command file. In the end, the program of TCP/IP developted with C language is tested. The result indicated, the system that was researched in my subject could process data according to network protocol, the transmission of the data through Ethernet is realized in this system.
