DSP以太网通信技术研究

摘要

阐述嵌入式以太网通信技术的一般原理.用TMS320F2812的DSP和RTL8019AS以太网控制芯片为电池化成设备控制系统实现了以太网通信功能.详细介绍硬件接口电路的设计,根据DSP的体系结构编写了简化的协议栈,并用DSP专用的实时操作系统DSP/BIOS与协议栈协同工作,最后用以太网测试程序对所设计的软、硬件进行了测试.%The general principle of embedded Ethernet communication technology was introduced. TI' sTMS320F2812 DSP and Realtek's RTL8019AS Ethernet control chip were employed to implement Ethernetcommunication for battery formation equipment control system. The hardware interface circuit design and theDSP-based simplified protocol stack with simplified architecture were presented to cooperate with DSP's DSP/BIOS real-time operation system,and then Ethernet testing program was applied to the software and hardwaredesigned.
