摘要： 高端路由器的IP层性能统计需要存储大量的数据,传统的方法用D触发器进行存储,往往消耗大量的逻辑单元和布线资源。文章给出一种用BlockRAM存储统计数据的设计方案,它有效利用FPGA内部的专用电路从而大量节省了逻辑和布线资源。该方案还具有良好的可扩展性。

Abstract: IP layer performance statistics in high-end router require a large mount of local data storage,traditionally implementation with standard flip-flops,which can quickly consume many logic cells and routing resources.A more efficient alternative is to use BlockRAM,which saves logic cell and routing resources and provides a more efficient implementation with the dedicated circuitry.It can also provide good scalability.
