摘要
在介绍Linux下设备驱动程序基础上,结合项目实例,详细说明了PCI-X数据采集卡的驱动程序编写方法,重点分析驱动程序效率问题,并提出针对高速数据采集卡驱动程序的优化方法。实践表明,该方法明显地提高了驱动程序的效率,在高速数据采集中具有广泛的参考意义。
Based on the introduction of device driver under Linux operation system, combined with project example, this paper explicates the coding process of PCI-X data sampling card driver, analyses the efficiency of driver code, and proposes an optimizing method to the high-speed data sampling card driver. Fact proves that this method improves the efficiency of the driver obviously.
