Floating point number can co-occurrently develop a prominent range of numbers and a high level of precision. Multiplication of floating point numbers found extensive use in wider range of technological and commercial calculations. It is needed to implement faster multipliers involving limited area and consuming reduced power. An IEEE-754 format established multiplier applying Vedic Urdhva — Tiryagbhyam...
The positioning technology is one of the most important technologies in the wireless sensor network. The paper describes the current international positioning on several existing technologies, including the based ranging RSSI, TOA, TDOA, etc. and non-centroid algorithm based on distance, Amorphous algorithm, APIT algorithm and so on. Dv_Hop algorithm is a distributed localization algorithm based on...
Wireless Sensor Networks(WSNs) consists of hundreds of nodes which are of low power, low cost, and tiny devices. The main functionality of these nodes is to sense the environment and send the sensed data to the observer. In order to validate and get the significance of sensing data, location information of the sensor node needs to be combined with the sensed data. In addition to this, there are many...
The growing concern in tracking, identification and localization systems has turn Radio Frequency Identification (RFID) technology into a mainstream in scientific research. In this technology, the phenomena known as the tag collision problem is becoming increasingly important, since it leads to a wastage of bandwidth, energy, and an increase in identification delay. There- fore, anti-collision protocols...
In this paper, a 6-bit 320-MS/s successive approximation register analog-to-digital converter (SAR ADC) is presented. The 2-bit/cycle technique and tri-level based charge redistribution technique are utilized to achieve high conversion rate and reduce the hardware cost. The proposed ADC is designed and implemented in a 65-nm CMOS process. Simulation results show that it accomplishes 48.52-dB SFDR,...
Hardware impairments of physical transceivers that create distortions degrade the performance of communication. This paper analyzes the performance with different relay selections which include partial relay selection and opportunistic relay selection in amplify-and-forward (AF) cooperative network with hardware impairments. Partial relay selection is that the relay node is selected depending on the...
Larger last level caches are being considered for bridging the performance gap between the processors and the memory subsystem. It requires much longer simulation time to exercise the whole cache and get accurate evaluation results. In this paper, we motivate the need for a trace-driven hardware/software co-simulation approach to solve this problem. We describe the components of the hardware/software...
