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

    動態(tài)可重構(gòu)高速串行總線(UM-BUS)是針對嵌入式系統(tǒng)小型化與一體化設(shè)計提出的一種具備遠(yuǎn)程擴(kuò)展能力和動態(tài)容錯特征的高速串行總線[1],可以解決CPS[2]以及物聯(lián)網(wǎng)在異構(gòu)接入、動態(tài)連接、可靠性、實時性等方面的問題。在基于UM-BUS總線的CPS應(yīng)用系統(tǒng)中,不僅需要通過總線本地接入傳感器進(jìn)行數(shù)據(jù)交互,還需要實現(xiàn)與其他CPS系統(tǒng)以及云服務(wù)之間的通信,因此,需要通過以太網(wǎng)與其他CPS系統(tǒng)進(jìn)行通信從而構(gòu)建更加全面完善的CPS系統(tǒng)。

    在基于UM-BUS總線的CPS應(yīng)用系統(tǒng)中,PC通過PCIe總線與UM-BUS總線主控制器相連,所以在進(jìn)行以太網(wǎng)通信時,PC需要跨過PCIe總線和UM-BUS總線去驅(qū)動以太網(wǎng),但現(xiàn)有的通用網(wǎng)卡驅(qū)動程序不能解決這個問題,因此提出一種基于UM-BUS總線的網(wǎng)卡驅(qū)動去解決跨兩種總線進(jìn)行設(shè)備訪問的問題。
