Abstract

The paper focuses on the problem of providing efficient run time support for different applications running on a real time system. The goal of our research is to develop a scheduling algorithm to allow independent applications to coexist on the same system. In order to meet the requested QoS, we assign each application a minimum bandwidth and guarantee that it never demands more. This algorithm does not require the exact knowledge of the execution times and interarrival times of the application tasks: hence, it is especially suited for soft real time and multimedia applications
