【摘要】：作为高性能计算机发展过程中的一项关键技术，I/O总线技术在传递指令和数据上起着举足轻重的作用。拥有PCI体系结构的数据传输系统在现代科技中仍然具有十分广泛的发展前景。无论是军事领域，还是民用领域，很多采用计算机控制的系统都需要数据传输接口，而PCI总线作为实用、廉价的接口恰好是一种合适的选择。因此，基于PCI总线的驱动程序开发变得尤为重要。本文依托教研室在研的几种数据采集和传输系统，目的是设计高效、可移植性强的驱动程序，并以图像采集系统为例，设计了相应的应用程序并进行验证。本文首先讨论了PCI总线的DMA中断传输的特点、原理。然后，阐述了PCI设备驱动程序编写时的准备工作，重点从驱动程序的编译环境、编写设计、编译、生成和安装等方面进行展示。安装驱动程序后设备管理器中加载该设备信息，说明驱动程序开发成功。最后，，以图像采集数据传输系统为例，设计了与驱动程序进行交互的应用程序，给出了应用程序开发的工具、应用程序界面的编写以及应用程序和硬件设备的调试。通过对监视器中的画面重演，验证了设计的驱动程序满足需求。
[Abstract]:As a key technology in the development of high-performance computers, I / O bus technology plays an important role in the transmission of instructions and data. Data transmission system with PCI architecture still has a very wide development prospect in modern science and technology. In both military and civilian fields, many computer-controlled systems require data transmission interfaces, and PCI bus is a practical and inexpensive interface. Therefore, the development of driver based on PCI bus becomes more and more important. The purpose of this paper is to design an efficient and portable driver based on several kinds of data acquisition and transmission systems in the teaching and research department. Taking the image acquisition system as an example, the corresponding application program is designed and verified. This paper first discusses the characteristics and principle of DMA interrupt transmission in PCI bus. Then, the preparation of PCI device driver is described, which focuses on the compilation environment, design, compilation, generation and installation of the driver. After installing the driver, the device manager loads the device information, indicating that the driver has been successfully developed. Finally, taking the image acquisition and data transmission system as an example, the application program which interacts with the driver is designed, and the tools for the development of the application program, the programming of the application interface and the debugging of the application program and the hardware device are given. By repeating the images in the monitor, it is verified that the driver designed meets the requirements.
