Abstract

In systems intended for handling continuous media (both video and audio), standard Linux does not provide suitable scheduling of the system resources regarding the complexity of the tasks. Where such a system consist of mixed applications, conventional computing is executed at the same time with hard real-time tasks, single scheduling policy is not able to satisfy the demands of the… real-time application. If proportional resource allocation is applied, each task can recive a fair share of a resource. Different sheduling policies are appropriate for diffent applications. In that matter, few Fair-sheduling algorithms are tried out. Fair-sheduling algorithms make sure that each resource gets proportional share of the CPU while executing the task. For implementing the algorithms and testing behaviour of the application, RT Linux is used.
