Like many technologies, low-cost Radio Frequency Identification (RFID) systems will become pervasive in our daily lives when affixed to everyday consumer items as “smart labels”. While yielding great productivity gains, RFID systems may create new threats to the security and privacy of individuals or organizations. This paper presents a brief description of(More)
The designs of high-performance processor architectures are moving toward the integration of a large number of multiple processing cores on a single chip. The IBM Cyclops-64 (C64) is a petaflop supercomputer built on multi-core system-on-a-chip technology. Each C64 chip employs a multistage pipelined crossbar switch as its on-chip interconnection network to(More)

This paper presents the overview and progress achieved in RF energy harvesting field. A modified form of existing CMOS based voltage doubler(More)
This paper presents the application of RFID (Radio Frequency Identification) to identify and authenticate the viewer for personalized and interactive services offered by the IPTV (Internet Protocol Television). Main purpose of the setup is to identify and authenticate the viewer, the person who is watching the TV, for parental control, payment services,(More)
This paper presents improved design of low power adder and analysis based on power reduction technique. Using example of adder and multiplier, low leakage power CMOS digital circuit is verified by respective benchmark suite for each example and compared with conventional design of adder and multiplier. Using various supply voltages and fault coverage as(More)
Low-power embedded system design has become extremely important in the most recent years. To fulfill system-level design requirements and time-to-market constraints, a power-driven methodology is essential during embedded system design. The aim of this paper is to introduce accurate and efficient power metrics included in a hardware/software (HW/SW)(More)
In this paper, we develop a new algorithm for the principle subspace tracking by orthonormalizing the eigenvectors using an approximation of Gram-Schmidt procedure. We carry out mathematical derivation to show that when this approximated version of Gram-Schmidt procedure is added to a modified form of Projection Approximation Subspace Tracking deflation(More)
This paper proposes a novel technique which provides energy efficient circuit design for sensors networks. The overall system presented requires a minimum number of independently communicating sensors and sub-circuits which enable it to reduce the power consumption by setting unused sensors to idle. This technique reduces hardware requirements, time and(More)
