Research And Realization Of DSP Embedded System Ethernet Accessing Technology

With the development at fall speed of communication technology, network technology and semiconductor technology, Internet technology design to industrial control and embedded system field permeate gradually. Internet has bring great convenience to people's study and life, has shortenned the distance on the space between men, and has already become an indispensable part in people's daily life, while the more important thing is that the embedded equipment's demand for Internet is urgent day by day.Realizing Internet interconnected is embedded systematic focus field and important direction of development this present.Through realizing a simple Application of network at Embedded System, this paper finishes embedded system Internet's accessing comparatively, and understands embedded system Internet's accessing basic principle,composing, configuration and the process of realization.This paper shows the solution of embedded system Internet's accessing through Ethernet by using of the network interface controller RTL8019 on the DSP platform (TMS320LF2407A),and the hardware design of network interface module introduced in details.and it realized embedded TCP/IP protocol partly.With Visual Basic,it has been realized that the the transfer of spectral analysis data on the Ethernet and the data can be displayed as an image by the client software.The results of experiments show that the solution proposed in this paper embedded system Internet's accessing based on DSP has better feasibility and practicability.
