This paper deals with literature survey of various existing converter topologies, which have been proposed for adjustable speed single phase induction motor drives (SPIMD). Included in the paper are several newly proposed Continue reading

# High-Speed and Low-Power Multipliers Using the Baugh-Wooley Algorithm and HPM Reduction Tree

The modified-Booth algorithm is extensively used for high-speed multiplier circuits. Once, when array multipliers were used, the reduced number of generated partial products significantly improved Continue reading

# High Speed 16×16-bit Low-Latency Pipelined Booth Multiplier

This paper presents a high-speed 16×16-bit CMOS pipelined booth multiplier. Actually in an n-bit modified Booth multiplier, because of Continue reading

# Transformer Protection Principles

Transformers are a critical and expensive component of the power system. Due to the long lead time for repair of and replacement of transformers, a major goal of transformer protection is Continue reading

# Adaptive Wiener Filters for Time-varying Channel Estimation in Wireless OFDM Systems

In wireless OFDM systems, the time-varying channel is often estimated by a Wiener filter-type MMSE estimator based on pilot symbols. Such an estimator, however, requires Continue reading

# 3D Image Segmentation Implementation on FPGA using EM/MPM Algorithm

In this Project, 3D image segmentation is targeted to a Xilinx Field Programmable Gate Array (FPGA), and verified with extensive simulation. Segmentation is performed using the Expectation-Maximization with Maximization of the Posterior Marginals (EM/MPM) Bayesian algorithm. This algorithm segments the Continue reading

# Chaos-based Random Number Generator in Finite Precision Environment

Yet having a very long history, how to generating good random number sequences still remains as a technical challenge. Although some mechanical ways, such as tossing a coin or rolling a dice, are commonly accepted as good random sources, they are obviously not been able to Continue reading

# Embedded Internet for Pulse Oximeters

In recent years there has been many investigations into sleeping disorders. Many studies are carried out in specially equipped units in which a patient is monitored whilst sleeping. Measurements that are taken are in the form of ECG, EMG, EEG, nasal airflow, and Continue reading

# Implementation Of Goldschmidt’s Algorithm With Hardware Reduction

Division algorithms have been developed to reduce latency and to improve the efficiency of the processors. Floating point division is considered as a high latency operation. This papers looks into one such division algorithm, examines the hardware block diagram and Continue reading

# High-Speed Floating-Point Divider with Reduced Area

This paper presents a new implementation of a floating-point divider unit with a competitive performance and reduced area based on proposed modifications to the recursive equations of Goldschmidt algorithm. The Goldschmidt algorithm takes advantage of parallelism in the Newton-Raphson method with the Continue reading

# Gradient algorithms for quadratic optimization with fast convergence rates

We propose a family of gradient algorithms for minimizing a quadratic function f(x) = (Ax; x)=2 ¡ (x; y) in Rd or a Hilbert space, with simple rules for choosing the step-size at each Continue reading
