RTX系统下并行I/O卡驱动程序的开发

Advantech Parallel I/O Card DriverDevelopment Based On RTX System

摘要:

研华PCI-1751板卡作为众多接口卡的一员被广泛使用，而出厂时该板卡并不携带RTX系统下的驱动程序，对于实时性要求较高的环境下，该板卡的使用是不太方便的。因此，开发RTX操作系统下PCI-1751板卡驱动程序成为了一个急需解决的问题。本文利用RTX提供的接口，使用I/O映射的方法操作板卡寄存器，讨论PCI-1751板卡的驱动开发流程，并对比Windows驱动与RTX驱动的实时性差异。

Abstract:

Advantech PCI-1751 card, as an important interface card, is widely used in lots of universities and institutes. However, this card doesn’t provide the user with the driver in RTX system after manufactured. For users who use this card in RTX environment, maybe it is not that convenient. This problem is very urgent to be solved. This paper, using the RTX API and I/O map functions, introduces the RTX driver developing process and finally shows the driver performance between Windows and RTX.
