摘　　要：动态可重构高速串行总线(UM-BUS)具有多通道并发冗余的特征以及远程存储访问能力,可为CPS、物联网中底层传感器与执行单元的远程接入提供一种高速可靠的解决方案。设计实现了一种基于UM-BUS总线连接的以太网卡的Linux驱动程序,解决了通过PCIe、UM-BUS两种总线进行设备跨总线访问的难题,实现了UM-BUS总线连接的以太网设备的驱动操作。使用第三方网络通信软件进行文件传输测试,网络通信功能正常稳定,通信速率与标准PCIe网卡基本一致,满足了CPS系统中通过UM-BUS总线上连接的以太网设备与外部系统进行数据通信的需求。Dynamic reconfigurable high-speed serial bus(UM-BUS)has the characteristics of multi-channel concurrent redundancy and the ability of remote storage access.It can provide a high-speed and reliable solution for the remote access of sensors and execution units in CPS and Internet of things.This paper designs and implements a driver of network card based on UM-BUS connection,solves the problem of device access through PCIe and UM-BUS multiple buses,and realizes the driver operation of Ethernet device connected by UM-BUS.In the Linux system,the third-party network communication software is used for file transmission test.The network communication function is normal and stable,and the communication rate is basically the same as that of the standard network card,which meets the requirements of data communication between the Ethernet equipment and the external through UM-BUS in the CPS system.
