基于TMS320C6678的双以太网UDP通讯系统设计与实现

Dual-Ethernet UDP Communication System Based on TMS320C6678

单一的以太网通信一旦故障无法迅速恢复,极易给对通信可靠性要求很高的现代武器系统带来质量隐患。以TMS320C6678多核DSP为处理器的双以太网主板,应用了SYS/BIOS实时系统软件内核,设计了一套双以太网UDP通讯系统,进行了严格的数据帧格式规定,设计了应答帧及帧重发机制和主从端口双收双发机制,在某型定位瞄准系统上进行了应用。应用结果表明:双以太网UDP通信冗余设计显著提高了系统的通信可靠性,效果良好。

Using a main board which includes dual-Ethernet that based on TMS320 C6678 and a Real Time Operating System（RTOS） core,a set of dual-Ethernet User Datagram Protocol（UDP） communication system is proposed in this paper.The system includes strict frames format,answering mode and retransmission mechanism of the frame.The dual-transmitting and dual-receiving mechanisms of the master-slave ports are also included in the the system.The designed dual-Ethernet UDP system has applied in a certain type of Location and Aiming system.
