摘要
提出了一种在嵌入式数字信号处理器系统中实现以太网通讯的解决方案。将TI公司的数字信号处理器TMS320F2812与以太网接口芯片DM9000A相结合,在2812 DSP芯片上移植了μC/OS—Ⅱ操作系统和LwIP轻型以太网协议栈,并用软件方式实现了TCP/IP网络协议,从而达到嵌入式系统同Internet通信的目的并已得到应用。系统结构简单、性价比高,具有广泛的应用前景。
The paper introduced a solution with Ethernet communication in embedded DSP system. Applied TMS320F2812 DSP chip from TI and DAVICOM＇ s latest Ethemet interface chip （ DM90OOA）, Ported μC/OS-Ⅱ RTOS in DSP system, and further ported LwlP （light weight IP） protocol stack in RTOS. So the solution achieved TCP/IP protocol by software and matched the embedded 2812 DSP Multi -task system communication with Internet. It get used on DSP project. There is a simplicity, high performance and low cost system, which has wonderful application.
