Dynamic voltage and frequency scaling (DVFS) is a technique for adjusting the speed and power consumption of processors, allowing performance to be traded for reduced power consumption. Since CPUs are typically the largest consumers of power in modern servers, DVFS can have a significant impact on overall server power consumption. Modern operating systems include DVFS governors, which interact ...

Commercial buildings are significant consumers of electrical power. Also, energy expenses are an increasing cost factor. Many companies therefore want to save money and reduce their power usage. Building administrators have to first understand the power consumption behavior, before they can devise strategies to save energy. Secondly, sudden unexpected changes in power consumption may hint at de...

Due to miniaturization of circuits mobility degradation, velocity saturation and power dissipation issues are critical in the design of VLSI circuits. In this paper various techniques to minimize power dissipation due to glitches are discussed. Total power consumption consists of two major parts like static power consumption and dynamic power consumption. In the total power, the static power is...

One of the features of wireless sensor networks is that the nodes in this network have limited power sources. Therefore, assessment of energy consumption in these networks is very important. What has been common practice has been the use of traditional simulators to evaluate the energy consumption of the nodes in these networks. Simulators often have problems such as fluctuating output values i...

Class-AB circuits, which are able to deal with currents several orders of magnitude larger than their quiescent current, are good candidates for low-power and high slew-rate analog design. This paper presents a novel topology of a class AB flipped voltage follower (FVF) that has better slew rate and the same power consumption as the conventional class-AB FVF buffer previously presented in liter...

In very deep submicron technologies (< 0.13 μm) the leakage power consumption becomes an important contribution to total power consumption. Consequently a new low-power design methodology will be required at circuit, architectural and system levels. This paper focuses on architecture comparison and aims at selecting the one with the minimum total power consumption by simultaneously optimizing s...

Energy efficiency is a major concern in the General Programming on Graphic Process Unit. Recent research focus on the measurement approach and energy optimization of Graphic Process Unit. Few studies provide insight to where and how power is consumed from the program perspective. The aim of this research was to build power consumption model to estimate the energy consumption for the application...

Power consumption is the predominant challenge in modern high-performance systems and is becoming increasingly important due to mobile applications. High power consumption leads to decreased battery lifetime, cooling challenges which limit form factors, and large on-chip temperatures which can decrease reliability. While stand-by and idle power can be minimized with many techniques, active-mode...
