New Trends in Real Time Operating Systems
Most of today's embedded systems are required to work in dynamic environments, where the characteristics of the computational load cannot always be predicted in advance. Still timely responses to events have to be provided within precise timing constraints in order to guarantee a desired level of performance. Hence embedded systems are by nature inherently real-time. Moreover, most of embedded systems work under several resource constraints due to space, weight, energy, and cost limitations imposed by the specific application. As a consequence, efficient resource management is a critical aspect in embedded system that must be considered at different architecture levels.
