HIGH THROUGHPUT AND LOW POWER REED SOLOMEN DECODER FOR ULTRA WIDE BAND FREQUENCIES

Abstract:- Reed Solomon (RS) codes have been widely used in a variety of communication systems such as space communication link, digital subscriber loops and wireless systems, as well as in networking Communications and magnetic and data storage systems. Continual demand for ever-higher data rates and storage capacity makes it necessary to devise very high-speed implementations of RS Decoders. Newer and faster implementations of the decoder are being developed ....etc

Ultra Low-Power Clocking Scheme Using Energy Recovery and Clock Gating

Hamid Mahmoodi, Member, IEE, Vishy Tirumalashetty, Matthew Cooke, and Kaushik Roy, Fellow, IEE


Abstract
A significant fraction of the total power in highly synchronous systems is dissipated over clock networks. Hence, low power clocking schemes are promising approaches for low-power design. We propose four novel energy recovery clocked flip-flops that enable energy recovery from the clock network, resulting in significant energ ....etc

Abstract New emerging applications in the areas of portable power generation, small turbo compressors and spindles require the development of ultrahigh-speed, low power electrical drives. A 500000 r/min, 100W electrical drive system is presented. Because of the ultrahigh-speed requirements, standard machine design and power electronic topology choices no longer apply and the complete drive system has to be considered. A permanent magnet machine with a slotless litz-wire winding is used, which results in a low motor inductance and a high fund ....etc

Abstract:

This project provides the experience of applying an advanced version of Spurious Power Suppression Technique (SPST) on multipliers for high speed and low power purposes. When a portion of data does not affect the final computing results, the data controlling circuits of SPST latch this portion to avoid useless data transition occurring inside the arithmetic units, so that the useless spurious signals of arithmetic units are filter out. Modified Booth Algorithm is used in this project for mul ....etc

Automated security systems are a useful addition to today's home where safety is an important issue. Vision-based security systems have the advantage of being easy to set up, inexpensive and non-obtrusive. This paper proposes an integrated dual-level vision-based home security system, which consists of two subsystems - a face recognition module and a motion detection module. The primary face recognition module functions as a user authentication device. On an event of a failure in the primary system, the secondary motion detection module acts as ....etc
