Abstract

Current Hard Real Time (HRT) kernels have their timely behaviour guaranteed on the cost of a rather restrictive use of the available resources. This makes current HRT scheduling techniques inadequate for use in a multimedia environment where we can make a considerable profit by a better and more flexible use of the resources. We will show that we can improve the flexibility and efficiency of multimedia kernels by combining Real Time Transactions with Deadline Inheritance policies under the Earliest Deadline First or the Deadline Monotonic rule. A currently running multimedia experiment shows a scheduling overhead of less than 0.5 percent. We also present the main ingredients for an open and adaptive Quality of Service (QoS) management. In particular a technique for rapid QoS schedulability analyses is offered. This technique can be applied to Hard Real Time analyses as well.
