摘　　要：复用与解复用是现代通信系统中重要的部分,它提高了通信系统的有效性.本设计采用时分复用方式,首次基于FPGA实现三路异步数据与一路同步数据的复用与解复用.这种设计与传统的方式相比,提高了同步复用与解复用的速度,降低了系统的功耗.在数据交叉连接系统中的应用表明,系统满足设计指标要求,并且可以在不增大复杂度的前提下提高复用链路速率,增大复用通道数,扩展其性能.Multiplexer and Demultiplexer, which improve the efficiency of the communication system, are a very important part in modern communication networks. In order to implement the multiplexing and demultiplexing on three channels of asynchronous data and one channel of synchronous data, the TDM is employed to design it based on the FPGA, which is the first time to our knowledge. Com- pared with the traditional methods, this method enhances the speed of multiplexing and demultiplexing and reduces the power consumption. The device shows it is good performances.
