With the advent of increased computing on mobile devices such as phones and tablets, it has become crucial to pay attention to the energy consumption of mobile applications. The software engineering field is now faced with a whole new spectrum of energy-related challenges, ranging from power budgeting to testing and debugging the energy consumption. To the best of our knowledge there has been l...

Data Processing is an important issue in wireless sensor networks (WSNs). However, constrained energy will lead to the network life deeply affected by the power consumption of data processing. Hence, reducing the power consumption becomes an important objective to improve the performance of WSNs. In this paper, an energy-efficient data processing scheme (EED) is proposed to reach the goal of sa...

Power consumption in the register file (RF) forms a considerable fraction of the total power consumption in a chip. With increasing instruction window sizes and issue widths, RF power consumption will suffer a significantly large growth. Using the fact that many of the register values are small and require only a small number of bits for representation, we propose a novel asymmetrically ported ...

Power consumption among sensors has always and will continue to be an issue among developers and deployers of such devices. Wireless sensor networks are even more power draining because they utilize a wireless radio communications device which requires more power than any other items on the sensor. This paper discusses some of the previous schemes to reduce power consumption through planning or...

Mobile Ad-hoc Network (MANET) is a self configuring infrastructure-less network of mobile devices connected by wireless They have undergone rapid growth in the past several years because of their application in military and rescue service, disaster recovery operations, mobile conferencing and many other applications. The Media Access Control (MAC) data communication protocol sub-layer provides ...

Power consumption from logic circuits, interconnections, dock distribution, on chip memories, and off chip driving in CMOS VLSI is estimated. Estimation methods are demonstrated and verified. An estimate tool is created. Power consumption distribution between ~ I I ~ I T O M ~ C ~ ~ O I W , clock distribution, logic gates, memories, and off chip driving are analyzed by examples. Comparisons are...

In a growing number of complex heterogeneous embedded systems, the relevance of software components is rapidly increasing. Issues such as development time, flexibility, and reusability are, in fact, better addressed by software-based solutions. Due to the processing regularity of multimedia and DSP applications, statically scheduled devices such as VLIW processors are viable options over dynami...

| The use of XOR gates has shown several advantages in modern circuit design, e.g. smaller representation size and better testability. In this paper we consider power consumption in XOR dominated circuits and compare such designs with traditional AND/OR logic. We investigate the suitability of using di erent delay models such as unit delay, fanout delay, and random delay in power estimation of ...
