OS for Graphics and Multimedia
نویسنده
چکیده
Multimedia and graphics data including video, audio, and realistic animations, are entertaining, informative, and intuitive. The information is continuously updated, in which the timing of the data is part of their semantics, and must be maintained both within a data stream and between related data streams. Operating system support for the soft real-time needs of multimedia applications is crucial and challenging. In this article, we discuss OS support for multimedia quality of service in a general-purpose and multi-user computing environment. We address the issues of (1) resource abstraction and accounting, (2) resource scheduling, and (3) solutions to priority inversion problems arising out of interactions between OS components.
