摘要：While technology is delivering increasingly sophisticated and powerful chip designs, it is also im-posing alarmingly high energy requirements on the chips. One way to address this problem is to managethe energy dynamically. Unfortunately, current dynamic schemes for energy management are relativelylimited. In addition, they manage energy either for energy efficiency or for temperature control, but notfor both simultaneously.In this paper, we design and evaluate for the first time an energy-management framework that tack-les both energy efficiency and temperature control in a unified manner. We call this general approachDynamic Energy Efficiency and Temperature Management (DEETM). Our framework combines severalenergy-management techniques and can activate them individually or in groups in a fine-grained manneraccording to a given policy. The goal of the framework is two-fold: maximize energy savings withoutextending application execution time beyond a given tolerable limit, and guarantee that the temperatureremains below a given limit while minimizing any resulting slowdown. The framework successfullymeets these goals. For example, it delivers a 40% energy reduction with a 10% application slowdown
