The operating system of an IC card should provide an appropriate interface to applications using IC cards. An incorrect choice of operations and data renders the card inefcient and cumbersome. The design principles of the UNIX operating system are most appropriate for IC card operating system design. The actual design that we recognise as UNIX (or any other current operating system for that mat...

Distributed multimedia applications are typical of a new class of workstation applications that require realtime communication and computation services to be effective. Unfortunately, there remains a wide gap between the development of real-time computing technology in the research community and the deployment of real-time solutions in commercial systems. In this work we explore technology for ...
