Abstract

Soft real-time techniques are needed for continuous multimedia communication systems. It is the intention of MMOSS, a real-time multimedia operating system supporting environment under development, to promote the integration of real-time techniques into such systems. MMOSS tries to support multimedia communications and applications by exploiting their special “soft” features, which are not present in or are not typical of other kinds of real-time applications. Some of these features are soft real-time guarantee, periodicity, error-tolerance, adaptability, etc. Feasible real-time models for these special features are provided. To run on a multiprocessor communication subsystem, MMOSS tries to support multimedia applications by providing them with a soft real-time execution environment.

多媒体通信子系统中的软实时操作系统支持
连续多媒体通信系统需要软实时技术。MMOSS是一个正在开发中的实时多媒体操作系统支持环境,其目的是促进实时技术与这些系统的集成。MMOSS试图通过利用其特殊的“软”特性来支持多媒体通信和应用程序,这些特性在其他类型的实时应用程序中不存在或不典型。这些特性包括软实时性保证、周期性、容错性、适应性等。为这些特殊的特征提供了可行的实时模型。为了在多处理器通信子系统上运行,MMOSS试图通过为多媒体应用程序提供软实时执行环境来支持它们。
