Energy-aware real-time multiprocessor scheduling has been studied extensively so far. However, some of the constraints associated with the practical DVS applications have been ignored for simplicity. These constraints include discrete speed, idle power, inefficient speed, and application-specific power characteristics etc. This work targets energy-aware scheduling of periodic real-time tasks on the...
A generalized dynamic energy performance scaling (DEPS) framework is proposed for exploring application-specific energy-saving potential in multiprocessor systems. This software-centric framework takes advantage of possible power control mechanisms to trade off performance for energy savings. Three existing technologies, i.e., dynamic hardware resource configuration (DHRC), dynamic voltage frequency...
The paper presents a time-triggered distributed object computing environment for embedded control systems such as automotive control systems. The time-triggered architecture is suitable for hard real-time systems. We present a time-triggered distributed object model as an extension to the time-triggered object model that consists of objects periodically updating their own attribute values. The model...
