摘要
阐述了Linux系统下实现设备驱动程序的基本框架。在介绍MPEG-4压缩卡工作原理的基础上,讨论了Linux系统下PCI接口的MPEG-4视频压缩卡驱动程序的设计与实现过程,并提供了相应的函数及程序的编写。实验结果证明了该驱动程序的实用性。
Based on the basic principle of MPEG-4 video compress card, this paper presents the general framework of developing device driver on Linux platform and describes the design and the implementation of the MPEG-4 video compress card driver, including relevant functions and programs. The experiment results prove the feasibility of the driver.
