This paper presents a low power strategy for test data compression and a new decompression scheme for test vectors. In our method, we propose an efficient algorithm for scan chain reordering to deal with the power dissipation problem. Further, we also propose a test slice difference (TSD) technique to improve test data compression. It is an efficient method and only needs one extra scan cell. I...

This paper proposes a new test data compression method for low power testing. To improve compression ratio, the proposed scheme uses the modified input reduction and novel techniques, a new scan flip-flop reordering algorithm and a newly proposed one block compression. The proposed method leads to better compression ratio with lower hardware overhead and lower power consumption than previous wo...

We present a novel algorithm that assigns codes to instructions during instruction code compression in order to minimize bus-related bit-toggling and thus reducing power consumption. The target application area is embedded systems, where power consumption is increasingly becoming a dominant design constraint. Our algorithm is based on a variant of quasi–arithmetic coding where coding allows for...

Air compressor is the critical part of a Compressed Air Energy Storage (CAES) system. Efficient and fast compression of air from ambient to a pressure ratio of 200-300 is a challenging problem due to the trade-off between efficiency and power density. Compression efficiency is mainly affected by the amount of heat transfer between the air and its surrounding during the compression. One way to i...

Ever-increasing test data volume and excessive test power are two of the main concerns of VLSI testing. The ‘‘don’t-care’’ bits (also known as X-bits) in given test cube can be exploited for test data compression and/or test power reduction, and these techniques may contradict to each other because the very same X-bits are likely to be used for different optimization objectives. This paper prop...

Expressions for peak and average powers required to produce a given average gradient in an accelerator section are given. They are valid for both lossy and lossless (superconducting) sections, for both traveling wave and standing wave sections, and for pulsed or continuous wave rf input. The expressions are given in terms of structure parameters that are equally applicable to traveling wave or ...

A wireless sensor network (WSN) is comprised of resource constrained devices called motes. Motes are battery operated and must conserve as much power as possible. Power usage for each mote is made up of processing data, sensing the surroundings, and sending and receiving packets. The bulk of power usage for standard WSN applications lies in the radio where receiving and sending packets are nece...

We consider a wireless node that randomly receives data from different sensor units. The arriving data must be compressed, stored, and transmitted over a wireless link, where both the compression and transmission operations consume power. Specifically, the controller must choose from one of multiple compression options every timeslot. Each option requires a different amount of power and has dif...
