摘要
针对飞行器遥测系统研制的需要,设计并实现了一种基于FPGA和W5300的可靠的百兆以太网接口。本接口包括变压器隔离模块、以太网控制器和中央控制器3部分。接口采用UDP传输协议,实现了以6.5MB/s的速度可靠、稳定地接收遥测设备的数据流的功能。设计针对UDP协议本身存在的不可靠性,在接口硬件电路设计和软件逻辑设计上分别做了可靠性优化,基本上保证了传输链路的可靠性,确保了数据的完整性。
Aiming at developing aircraft remote-measuring system, a fast Ethernet interface based on FPGA and W5300 was designed, including its transformer isolation module, Ethernet controller and central controller. This interface adopts UDP mode to receive data flow from other devices reliably and steadily at 6.5MB/s; and considering the UDP uncertainty, having hardware circuit design and software logic sequence design optimized to ensure reliable transmission link and data integrality.
