Abstract

A computer system optimized for real-time applications which provides increased performance over current computer architectures. The system includes a standard local bus, such as the PCI bus, and also includes a dedicated real-time bus or multimedia bus. The PCI bus and the multimedia bus are comprised on the motherboard. One or more PCI devices or multimedia devices are comprised on the motherboard and are coupled to the PCI bus and the multimedia bus. In one embodiment, the motherboard includes PCI bus and multimedia bus connector slots for receiving add-in cards. In this embodiment, multimedia device expansion cards each include two connectors which correspond to the PCI bus and the multimedia bus. Thus multimedia devices such as video cards, audio cards, etc., as well as communications devices, transfer real-time data through a separate bus without requiring arbitration for the PCI bus. The computer system of the present invention thus provides much greater performance for real-time applications than prior systems.
