Online dynamic power management (DPM) strategies refer to strategies that attempt to make power-mode-related decisions based on information available at runtime. In making such decisions, these strategies do not depend upon information of future behavior of the system, or any a priori knowledge...
Lower threshold voltages in deep submicron technologies cause more leakage current, increasing static power dissipation. This trend, combined with the trend of larger/more cache memories dominating die area, has prompted circuit designers to develop SRAM cells with low-leakage operating modes...
System-level power management has become a key technique to render modern wireless communication devices economically viable. Despite their relatively large impact on the system energy consumption, power management for radios has been limited to shutdown-based schemes, while processors have...
The unique characteristics of multimedia/embedded applications dictate media-sensitive architectural and compiler approaches to reduce the power consumption of the data cache. Our goal is exploring energy savings for embedded/multimedia workloads without sacrificing performance. Here, we present...
This paper introduces a systematic approach to power awareness in mobile, handheld computers. It describes experimental evaluations of several techniques for improving the energy efficiency of a system, ranging from the network level down to the physical level of the battery. At the network...
We address the problem of energy-optimal voltage scheduling for fixed-priority hard real-time systems, on which we present a complete treatment both theoretically and practically. Although most practical real-time systems are based on fixed-priority scheduling, there have been few research...
Portable embedded computing systems require energy autonomy. This is achieved by batteries serving as a dedicated energy source. The requirement of portability places severe restrictions on size and weight, which in turn limits the amount of energy that is continuously available to maintain...
