A generic built-in self-test needed for SoC devices implementing for low power consumption. In this we proposed a new technique to generate a fully pre-computed test set in a deterministic BIST using simple gray counter within a reasonable clock cycles. Conversely, we consider only a small part of the circuit which is to be tested is active and the other parts of the circuit are fed with low le...

Conditional capture and conditional precharge techniques for high-performance flip-flops are reviewed in terms of power and delay. It is found that application of conditional techniques can improve Energy-Delay Product for up to 14% for 50% input activity and save more than 50% in power consumption for quiet input. This property makes conditional methods suitable for high-performance VLSI systems.

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

High-speed recursive digital filters are of interest for applications focusing on high-speed as well as low power consumption because excess speed can be traded for low power consumption through the use of power supply voltage scaling techniques. This paper gives an overview of high-speed recursive digital filters based on frequency masking techniques.

EAF plants normally consume coal and coke as reactants, alloying elements, or fuel. The price of these materials varies from € 0.20-0.35/kg. This is while nearly 10 million pieces of tires are annually discarded in Iran. The present study shows that scrap tires can be used as a substitute for coal and coke in EAF plants. Thirteen grades of steel including low, medium, and high carbon steels as ...

SRAM is designed to provide an interface with CPU and to replace DRAMs in systems that require very low power consumption. Low power SRAM design is crucial since it takes a large fraction of total power and die area in high performance processors. A SRAM cell must meet the requirements for the operation in submicron/nano ranges. 8T SRAM is traditionally concerned as a more reliable memory cell,...

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...

Power consumption in embedded applications can be reduced either by hardware, software or both. Each instruction of a given program activates specific parts of the microprocessor. Therefore, the election of the correct instruction can generate a reduction of the power consumed by the processor. This paper presents a survey of software power reduction techniques from several authors and the futu...

In order to solve the environmental crisis problem and to realize the sustainable environment, we need the efforts to reduce energy consumption. It is reported that the energy consumption by IT including communication will rapidly grow. Based on this situation, Japan Science and Technology Agency (JST) has begun the project of “Ultra low power consumption information technology” under the umbre...
