基于FPGA的交换结构研究与实现

Research and Implementation of Switching Structure Based on FPGA

交换结构的选择对交换效率影响重大,通过对单级交换和多级交换结构比较分析后,提出了一种兼容两者的缓冲交叉式交换结构,并在基于Xilinx公司Virtex-6系列FPGA上搭建交换系统,对其进行仿真实现,得出此设计在本交换系统确实可行的结论。

The choice of switching structure has a great impact on the switching efficiency.After comparing and analyzing the single-level switching and multi-level switching structure,a new buffered crossbar structure compatible with both is proposed and simulated and implemented on the Xilinx Virtex-6 series FPGA.The conclusion is that this design is feasible in the switching system.
