摘要
Hand held battery powered devices are becoming increasingly complex, with embedded applications that regularly demonstrate very dynamic behavior and requiring advanced functionality. To avoid prohibitively high power consumption, novel techniques are needed to handle the increased dynamicity and complexity, e.g., through use of system scenario based design. In this paper a framework for system scenario resource management is presented and evaluated with the H264/AVC encoder control structure on an EFM32 microcontroller. By using DFS as a system knob, we obtain significant power reductions for different system scenarios occurring dynamically while the application is running. The framework overhead is negligible.
