With the scaling of technology and the need for high performance and more functionality, power dissipation becomes a major bottleneck for microprocessor systems design. Also clock power can be significant in high performance systems. In this paper, a low power ALU for efficient datapath is proposed. In ALU, based on the observation, that while one functional unit is working other functional uni...

Broadcasting live digital TV to a small battery-powered handheld device is very challenging. One of the most promising technologies to provide such services is DVB-H (Digital Video Broadcasting over Handheld). Power consumption has always been one of the most crucial challenges for handheld devices. In this paper, a novel Adaptive Modulation and Coding (AMC) framework is proposed for DVB-H syst...

The 3GPP long term evolution(LTE) not only offer high bandwidth for data transfer but also exhaust the User Equipment(UE)’s battery life quickly. In order to save the UE’s battery Life, discontinuous reception(DRX) is specified to reduce the UE’s power consumption, DRX allow the UE to turn off RF module when there is no data need to transfer. This work focus on analysis DRX mechanism with diffe...

Wireless hosts are usually powered by batteries which provide a limited amount of energy. Therefore, techniques to reduce energy consumption are of interest. One way to conserve energy is to use power saving mechanisms. Power saving mechanisms allows a node to enter a doze state by powering off its wireless network interface when deemed reasonable. Another alternative is to use power control sc...

Mobile terminals for future wireless communication need to limit the energy consumption to prolong the operational times and to avoid active cooling. In fact, without new approaches for energy saving, there is a significant threat that the 4G mobile users will be searching for power outlets rather than network access, and will become once again bound to a single location; some authors describe ...

Further, the electronic control that BLDC motors offer is critical to statutory vehicle requirements such as energy-saving, reduced environmental impact, and the creation of safer vehicles. BLDC motors are also useful for variable-speed applications where space is tight, such as fuel pump control and electronic power steering. In these types of applications, electronic control is essential due ...
