Execution Time Monitoring in Linux

This paper presents an implementation of an execution time monitor (ETM) which can be applied in a resource management framework, such as the one proposed in the open media platform (OMP). OMP is a European project which aims at creating an open, flexible and resource efficient software architecture for mobile devices such as cell phones and handsets. One of its goals is to open up the possibility for software portability and fast integration of applications, in order to decrease development costs. The task of the ETM is to measure task execution time and provide this information to the scheduler which then can schedule tasks in a more efficient and dynamic way. This implementation is our first step towards a full resource management framework that later will include a hierarchical scheduler, for soft real-time systems.
