Abstract: A computer system optimized for real-time applications which provides increased performance over current computer architectures. The system includes a standard local system bus or expansion bus, such as the PCI bus, and also includes a dedicated real-time bus or multimedia bus. Various multimedia devices are coupled to one or more of the expansion bus and/or the multimedia bus. The computer system includes a dedicated or centralized I/O processor coupled to one or more of the expansion bus and/or the multimedia bus which operates to direct or pull stream information through the system. The centralized I/O processor comprises a memory for storing data rate, data periodicity, data source, and data destination information for said multimedia devices. The computer system of the present invention thus provides much greater performance for real-time applications than prior systems.

Abstract translation: 针对实时应用程序进行了优化的计算机系统，提高了当前计算机体系结构的性能。 该系统包括标准本地系统总线或扩展总线，如PCI总线，还包括一个专用的实时总线或多媒体总线。 各种多媒体设备耦合到一个或多个扩展总线和/或多媒体总线。 计算机系统包括耦合到一个或多个扩展总线和/或多媒体总线的专用或集中的I / O处理器，其操作以通过系统引导或引导流信息。 集中式I / O处理器包括用于存储用于所述多媒体设备的数据速率，数据周期，数据源和数据目的地信息的存储器。 因此，本发明的计算机系统为实时应用提供比现有系统更大的性能。
