本文提出了一个执行时间监视器（ETM）的实现，它可以应用于资源管理框架，如开放媒体平台（OMP）中提出的资源管理框架。OMP是一个欧洲项目，旨在为移动设备（如手机和手持设备）创建一个开放、灵活和资源高效的软件架构。其目标之一是为软件可移植性和应用程序的快速集成开辟可能性，以降低开发成本。ETM的任务是测量任务执行时间，并将此信息提供给调度器，然后调度器可以以更有效和动态的方式调度任务。这个实现是我们迈向一个完整的资源管理框架的第一步，这个框架随后将包括一个用于软实时系统的分层调度器。
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.
