| 摘 要： | 介绍了一种串口数据交换的设计方案。利用FPGA、单片机、时隙交换(TSI)芯片实现大容量的数据终端DTE和数据信道DCE无阻塞的交换,以及在时间轴上的无缝隙切换。同时,具有硬件冲突检测功能以及信道振铃检测功能,为数据终端和数据信道能够正常通信提供了保障。其交换规模可达到40×40×8,完成多串口数据线与握手线的全交换,完全满足了多个串口数据终端和数据信道交叉通信中的要求。

| Abstract: | A design of serial port data exchange is introduced.The design,which makes use of FPGA,single chip microcomputer and time slot interchange(TSI)chip,realizes non-blocking exchange among large numbers of DTEs and DCEs,and seamless switchover in the time line.At the same time,the two functions of detecting hardware collision and channel ringing make sure data terminals and data channels communicate normally.The exchange capability attains to 40×40×8,so as to realize full exchange of data signals and handshake signals of multiple serial ports,which fulfils the need of cross communication among large numbers of data terminals and data channels. |
