摘要
AVStream是一种遵循WDM模型的、新型的、同时支持音频和视频的多媒体类驱动架构。通过实例讲述了AVStream驱动程序属性配置原理;并且围绕驱动中数据的传递过程,重点说明了AVStream驱动程序内中断以及直接数据存储(DMA)的处理和应用,为基于AVStream的多媒体通用设备微型驱动专业开发人员提出了参考开发要点。
AVtream is a new multimedia architecture followed WDM model which could support audio and video stream stimultaneously. How to config properties of an AVStream are illustrated by example. Focusing on the route of data transfer, DMA and interrupt in AVStream are presented emphasisly, which provide a reference design for professional programmer of AVStream-based general multimedia device design.
