Abstract： 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.
Key words : UM-BUS,；Ethernet driver,；Linux；cross bus driver
