This paper deals with the analysis of evolutionary design in different approximate circuit designs. The key character of these designs is to relax the functionality of the circuits to minimize energy consumption or area of the chip. Keywords—Approximate design, Cartesian genetic programming, gates scaling.

Maintaining factory default battery endurance rate over time in supporting huge amount of running applications on energy-restricted mobile devices has created a new challenge for mobile applications developer. While delivering customers’ unlimited expectations, developers are barely aware of efficient use of energy from the application itself. Thus, developers need a set of valid energy consump...

A 23 GHz Ge/SiGe multiple quantum well electroabsorption waveguide modulator is demonstrated with 10 dB extinction ratio (ER). 9 dB ER is achieved with 1V swing with energy consumption limited to 108 fJ per bit. Keywords-component; Quantum-confined Stark effect, Ge/SiGe, multiple quantum well modulators

Over the past ten years cache configurations and their designs have increased in importance, energy efficiency, speed, and in other aspects as well. The goal of this paper is to discuss the energy and performance efficiency of different cache designs throughout the years. A good scale efficiency for a cache could be considered a measure of its latency and energy consumption. To optimize cache e...

The draft Auckland Unitary Plan outlines the future land used for new housing and businesses with Auckland population growth over the next thirty years. According to Auckland Unitary Plan, over the next 30 years, the population of Auckland is projected to increase by one million, and up to 70% of total new dwellings occur within the existing urban area. Intensification will not only increase th...

Mobile Cloud Computing is an evolving technology that integrates the concept of cloud computing into the mobile environment. Smartphones are boon in the world of technology but they have certain limitations (e.g. battery life, network bandwidth, storage, energy) when running complex applications which require large computations. Using Cloud Computing in mobile phones, these limitations can be a...

Energy efficiency is vital for a mobile terminal. In this paper we investigate how to choose the right parameter settings at run-time so that the energy consumption is minimized while satisfying the required level of service. To use a real world example, the energy consumption of a third generation telephone WCDMA downlink receiver with turbo decoding forward error correction is considered. A t...

Device specific power consumption information leads to a high potential for energy savings. Smart meters are currently deployed in several countries, but they are only able to track the overall consumption in domestic and commercial buildings. One promising option to gain device specific information is called Nonintrusive Load Monitoring (NILM), which can be of great use in combination with sma...

Wireless sensor networks include small nodes which have sensing ability; calculation and connection extend themselves everywhere soon. Such networks have source limitation on connection, calculation and energy consumption. So, since the nodes have limited energy in sensor networks, the optimized energy consumption in these networks is of more importance and has created many challenges. The prev...
