End-system resource management for digital audio and video

Research at Lancaster University is aimed at providing system software support for distributed real-time and multimedia applications in an environment of conventional workstations and high-speed networks. Our approach is to use a micro-kernel operating system, specifically Chorus, to underpin both UNIX and real-time applications. A standard UNIX SVR4 'personality' included with Chorus is used to support UNIX applications alongside our real-time extensions. We briefly review resource management aspects of the design and deal with CPU scheduling, network resource management and memory management issues.<
