嵌入式测试系统中UDP/IP协议栈的移植与实现

Transplant and Implementation of UDP/IP Protocol Stack in Embedded Test System

根据分布式测发控系统单机的通信要求,基于DM9000以太网控制器芯片和BM3101嵌入式处理器进行了以太网网络接口的设计,实现了无操作系统的UDP/IP协议栈的移植,并详细介绍了数据发送和接收的具体实现过程。对系统通信进行了测试,结果表明UDP通信整体稳定可靠,能够满足实际应用需求。

According to the requirements of the communication in test launch and control system, a ethernet network interface is designed, which is based on DM9000 ethernet controller chip and BM3101 embedded processor, and the transplant of UDP/IP protocol stack is implemented without any operating system. A de- tailed description of data transmission and receiving is shown in this paper. The system communication is tested and the result shows that UDP communication is reliable and can meet the requirements in practice.
