Integrated circuits that sense, receive, transmit, and process signals are the eye, ears, and nose of the hitechnical field of the millennium. To process/store/analyee signals acquired from sensors, hybrid systems with Rexible and adaptable Intelligent Information Processing and Perception (IIPP) are needed. Genetic Algorithms (GA) present a suitable pre-processing operation hecause of their good convergence to optimum solutions and characterination capabilities. Most of GAs are built via software because of their ease of editing and eustomization. Less attention has been given to hardware implementation of such algorithms. In this paper we present a hardware design approach of a GA for optimum measurements representationjcharacterization to a following IIPP stage. A multilevel verification of the GA is performed via VHDL. In particular the design of efficient universal multipliers and dividers is addressed. A new time efficient approach for Crossover based on preassigned least error value is proposed. The Crossover scheme is called Half Siblings and D Clone. Such a scheme needs 10 iterations to converge the system proposed for sensor measurement characterization. This takes 7680 clock cycles, which is only 96 μsec when implemented in the 0.25 pm CMOS technology. © 2002 IEEE.

ANALYSIS OF 3-D MICROWAVE RESONATORS USING COVARIANT-PROJECTION ELEMENTS

引用

IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES 1991年第11期39卷 1895-1899页

作者： WEBB, JP MINIOWITZ, R Computational Analysis and Design Laboratory Department of Electrical Engineering McGill University Montreal QUE Canada Electromagnetics Department RAFAEL Advanced Defense Systems Limited Haifa Israel

Three-dimensional microwave resonators of arbitrary shape can be analyzed with the finite element method using covariant-projection elements, curvilinear bricks which impose only tangential field continuity. The method produces no spurious modes, and works well even when sharp metal edges are present. The matrices involved, though large, are sparse;an appropriate sparse eigenvalue algorithm allows the method to run in modest amounts of memory. Results are presented for a number of test cases, including a rectangular microstrip resonator.

Flexible controller design and its application for concurrent execution of buffer centric dataflows

Journal of VLSI Signal Processing systems for Signal, Image, and Video Technology 2007年第3期47卷 233-257页

作者： Mun, Junhee Cho, Shung Han Hong, Sangjin Mobile Systems Design Laboratory Department of Electrical and Computer Engineering Stony Brook University-SUNY Stony Brook NY 11794-2350 United States

This paper presents a flexible controller structure for concurrent processing of memory centric coarse grain data flows. We propose a design flow based on block level pipelining where concurrency among processing blocks is fully maintained. The controller is dynamically reconfigurable to support dynamic data-flow structure changes by localizing control signals. The proposed control design method isolates controllers and processing logics such that system integration is simplified while controllers are locally configured from orthogonal global information. The controller also supports interfacing with external processors for asynchronous processing. The controller for heterogeneous processing blocks is synthesized and verified using Verilog and SystemC on FPGA. We present an example demonstrating the effectiveness of the controllers where dynamic reconfiguration of the execution is feasible. © Springer Science+Business Media, LLC 2007.

NOVEL TEST STRUCTURE FOR THE MEASUREMENT OF ELECTROSTATIC DISCHARGE PULSES

引用

IEEE TRANSACTIONS ON SEMICONDUCTOR MANUFACTURING 1991年第3期4卷 213-218页

作者： LENDENMANN, H SCHRIMPF, RD BRIDGES, AD Integrated Systems Laboratory Swiss Federal Institute of Technology Zurich Switzerland Department of Electrical and Computer Engineering University of Arizona Tucson Tucson AZ USA AT and T Microelectronics Allentown PA USA

A test chip to measure electrostatic discharge (ESD) events was designed and fabricated. The structure for the measurement of the pulses was based on a floating-gate field-effect transistor. Experiments showed that the shift of the device characteristics following an ESD event can be used to measure ESD pulse magnitudes down to approximately 60 V.

ISBN: (纸本)0818667109

A system has been developed for the classification of intracardiac electrograms (ICEG). The system is comprised of an analogue VLSI neural network, an implantable cardioverter defibrillator (ICD) and a PC based software training environment. Analogue implementation techniques were chosen to meet the strict power and area requirements of implantable systems. The robustness of the neural network architecture reduces the impact of noise, drift and offsets inherent in analogue approaches. The neural network chip is a 10:6:3 multilayer perceptron with on chip digital weight storage, a bucket brigade input to feed the ICEG to the network and has a winner take all circuit at the output. The chip was implemented in 1.2 μm CMOS and consumes less than 200 nW maximum average power in an area of 2.2×2.2 mm2. The network was trained in loop with the ICD in the signal processing path. Results are presented, demonstrating the advantages of combining neural network and and low power analogue circuit techniques by distinguishing certain dangerous arrhythmia, not currently possible in existing ICDs. © 1994 IEEE.

ISBN: (纸本)0818642602

The authors examine the performance of a simple recurrent neural network when applied to a temporal sequence prediction problem. It is shown that when trained with a combination of optimization techniques, a simple recurrent neural network can provide the same performance as the cascade correlation architecture in fewer training epochs. Conclusions are that for this and other finite-state based problems, subject to the training algorithm making optimal use of the architecture, the performance is determined by the number of weights and number of recurrent nodes. It is shown that by using a network trained in this manner on this problem, a radial basis function network can be used to extract a higher-level representation from the recurrent nodes in the network. More importantly, this network is able to map the extracted representation onto the representation that was used to create the input sequence. © 1993 IEEE.

作者： Jabri, Marwan A. Wang, Raymond J. Systems Engineering and Design Automation Laboratory Department of Electrical Engineering The University of Sydney NSW2006 Australia

State-of-the-art speech processors in cochlear implants perform channel selection using a spectral maxima strategy. This strategy can lead to confusions when high frequency features are needed to discriminate between sounds. We present in this paper a novel channel selection strategy based upon pattern recognition which allows "smart" channel selections to be made. The proposed strategy is implemented using multi-layer perceptrons trained on a multispeaker labelled speech database. The input to the network are the energy coefficients of N energy channels. The output of the system are the indices of the M selected channels. We compare the performance of our proposed system to that of spectral maxima strategy, and show that our strategy can produce significantly better results. © NIPS 1995: Proceedings of the 8th International Conference on Neural Information Processing systems.
