嵌入式Linux下PCI设备驱动的设计与实现

Design and implement of PCI device driver based on Linux

PCI局部总线具有使用方便、数据传输率高等特点,已成为计算机必备的一种接口。Linux是一种日趋成熟完善的操作系统,越来越多的软硬件厂商开始使用Linux平台开发自己的产品,因而对基于该平台的设备驱动程序的需求也愈来愈多。介绍了Linux驱动程序开发的一般方法,并实现了流媒体数据缓存PCI卡在Linux环境下的驱动程序。

Nowadays PCI bus has become a universal bus with its characteristics of easy using and high data transfer rate.With the development of Linux,there are more and more companies to develop their productions under Linux operation system.So there are more and more requirements to develop the devices driver for hardware under Linux.This paper introduces a method to develop device drivers based on Linux,and implement the streaming media data cache PCI card driver for Linux.
