The integration of video and audio into computers requires the support of continuous streams at the hardware level. This paper proposes a bus bandwidth management and access arbitration scheme for a multimedia workstation. It is assumed that a multimedia workstation consists of several specialized processing modules which are linked by a packet-switched bus. Using the proposed scheme, the bus can support a mix of real-time continuous media streams and random transactions while fulfilling special requirements corresponding to each traffic type. Specifically, the bus provides very fast response to random transactions and serves continuous media streams in such a way that no piece of data falls behind its deadline. Furthermore, the performance with respect to continuous media traffic is maintained independent of time variations of randomm traffic. Practical implementation guidelines are provided. Finally, the performance of the proposed scheme is compared with other possible approaches.
