NT下图像压缩解压卡驱动程序的设计与实现

摘要

多媒体设备驱动程序的设计是分层的，具有多层结构。不同种类的多媒体设备其驱动程序的设计方法各不相同。该文分析了多媒体设备驱动程序的体系结构，和图像压缩解压卡的驱动程序方案。描述了核心态驱动程序的处理流程，提供了用户态驱动程序的几个主要例程的设计流程。%Multimedia driver can be classified as User-mode multimedia drivers and Kernel-mode multimedia driver. The design method is varied greatly. This article provides a general description of the multimedia driver architecture and design method of the driver of video Compressor.
