摘　　要：大容量延迟线是设计实时卷积滤波器的一个关键技术。该文讨论了几种实现延迟线的方法,介绍了一种基于FPGA内嵌BlockRAM的延迟线设计新方法,该方法能大大节省FPGA的CLB资源,且结构简单灵活、易于扩展,并在某型飞机座舱综合图形显示系统中得到了应用。The design of a large-capacity delay line is a key technology of real-time convolver. This paper discusses several design methods of delay line, furthermore, a new design method of delay line based on FPGA embedded Block RAMs is introduced. This method not only can decrease the used FPGA＇s CLB resources, but also has a simple and flexible structure, which can be extended easily. This method has been allied to a graphics display system in aircraft cockpit successfully.
