Embedded systems present severe limitations in terms of processing and memory capabilities and are often powered by batteries, making energy an important resource to be managed. This work explores energy as a parameter for Quality of Service (QoS) of embedded systems. The goal is to guarantee the battery lifetime specified by the application and yet(More)
Power management strategies for embedded systems typically rely on static, application driven deactivation of components (e.g. sleep, suspend), or on dynamic voltage and frequency scaling. However, the design and implementation of these strategies in embedded operating system often fail to deal with real-time and quality-of-service (QoS) requirements. The(More)
Deeply embedded systems are designed to perform a certain set of tasks, and present limitations regarding processing and memory capabilities. In many cases, these systems are powered by batteries, requiring efficient power management. In this paper, we present a dynamic power manager with no significant overhead to the application. This manager uses the(More)
