摘要
在智能变电站二次设备系统中,大量使用FPGA芯片,以协助CPU进行数据处理、传输和控制等工作。为增强扩展性,降低硬件成本,经常会在一个板件上放置2片FPGA,因此FPGA间的数据传输便是需要考虑的问题。对此,提出在同一板件上的2片FPGA间的数据传输方法,并在项目中得以实现。经实际验证,该传输方法可保证400 Mb/s的可靠传输速度,满足实际应用需求。
In the secondary equipment system of intelligent substation,FPGA chips are widely used to assist CPU in data processing,transmission,control etc.To enhance scalability and reduce hardware costs,two FPGA are often used on one board,so data transmission between FPGA is a problem to be considered.A data transmission method between two FPGA on the same board is proposed,which has been realized in the project.Through the actual verification,the transmission method can ensure the reliable transmission speed of 400 Mb/s,and meet the practical application requirements.
