Power Efficient Folding of Pipelined LMS Adaptive Filters with Applications to Wireline Digital Communications
Journal of VLSI signal processing systems for signal, image and video technology - Tập 25 - Trang 199-213 - 2000
Ahmed F. Shalash, Keshab K. Parhi
In this paper, a new two-step algorithm is introduced for power efficient implementation of the folding algorithm transformation of the LMS adaptive FIR filters. The first step handles the scheduling within the folding sets to reduce the switching activity using a greedy algorithm solution for the traveling sales person (TSP) NP-hard problem. The greedy algorithm gives a sub-optimal solution of th...... hiện toàn bộ

A Hybrid Neuro-Fuzzy System for Adaptive Vehicle Separation Control
Journal of VLSI signal processing systems for signal, image and video technology - Tập 21 - Trang 15-29 - 1999
I-Chang Jou, Chung-Jyi Chang, Huey-Kuo Chen
The primary purpose of this paper is to develop a robust adaptive vehicle separation control in the increasingly important roles of intelligent transportation system (ITS). A hybrid neuro-fuzzy system (HNFS) is proposed for developing the adaptive vehicle separation control to minimize the distance (headway) between successive cars. This hybrid system consists of two modules: a headway identificat...... hiện toàn bộ
Real-time high-energy physics applications on DECPeRLe-1 programmable active memory
Journal of VLSI signal processing systems for signal, image and video technology - Tập 12 - Trang 21-33 - 1996
Laurent Moll, Jean Vuillemin, Philippe Boucard, Lars Lundheim
The future Large Hadron Collider (LHC) to be built at CERN1 by the turn of the millenium, provides an ample source of challenging real-time computational problems. We report here some results from a collaboration between CERN EAST2 (RD-11) group and DEC-PRL PAM3 team. We present implementations of the four foremost LHC algorithms on DECPeRLe-1 [1]. Our machine is the only one which presently meets...... hiện toàn bộ

A Programmable Imager for Very High Speed Cellular Signal Processing
Journal of VLSI signal processing systems for signal, image and video technology - Tập 23 - Trang 305-318 - 1999
Elisenda Roca, Servando Espejo, Rafael Domínguez-Castro, Gustavo Liñán, Ángel Rodríguez-Vázquez
In this paper a programmable imager with averaging will be described which is intended for averaging of different groups or sets of pixels formed by n × n kernels, n × m kernels or independent pixels of the array. This imager is a 64 × 64 array which uses passive pixels that can be randomly accessed. The read-outstage includes a sole charge amplifier with programmable gain, a sample-and-hold struc...... hiện toàn bộ
Bidiagonalization and symmetric tridiagonalization by systolic arrays
Journal of VLSI signal processing systems for signal, image and video technology - Tập 1 - Trang 279-285 - 1990
R. Schreiber
We give a systolic algorithm and array for bidiagonalization of ann × n matrix inO(n logn) time, usingO(n 2) cells. Bandedness of the input matrix may be effectively exploited. If the matrix is banded, withp nonzero subdiagonals andq nonzero superdiagonals, then 4n ln(p+q)+O(n) clocks and 2n(p+q)+O((p+q) 2+n) cells are needed. This is faster than the best previously reported result by the factor l...... hiện toàn bộ
Feature Fusion for the Detection of Microsleep Events
Journal of VLSI signal processing systems for signal, image and video technology - Tập 49 - Trang 329-342 - 2007
Martin Golz, David Sommer, Mo Chen, Udo Trutschel, Danilo Mandic
A combination of linear and nonlinear methods for feature fusion is introduced and the performance of this methodology is illustrated on a real-world problem: the detection of sudden and non-anticipated lapses of attention in car drivers due to drowsiness. To achieve this, signals coming from heterogeneous sources are processed, namely the brain electric activity, variation in the pupil size, and ...... hiện toàn bộ
Monte Carlo Bayesian Signal Processing for Wireless Communications
Journal of VLSI signal processing systems for signal, image and video technology - Tập 30 - Trang 89-105 - 2001
Xiaodong Wang, Rong Chen, Jun S. Liu
Many statistical signal processing problems found in wireless communications involves making inference about the transmitted information data based on the received signals in the presence of various unknown channel distortions. The optimal solutions to these problems are often too computationally complex to implement by conventional signal processing methods. The recently emerged Bayesian Monte Ca...... hiện toàn bộ
Error detection in arrays via dependency graphs
Journal of VLSI signal processing systems for signal, image and video technology - Tập 4 - Trang 331-342 - 1992
Edwin Hsing-Mean Sha, Kenneth Steiglitz
This paper describes a methodology based on dependency graphs for doing concurrent run-time error detection in systolic arrays and wavefront processors. It combines the projection method of deriving systolic arrays from dependency graphs with the idea of input-triggered testing. We call the method ITRED, forInput-driven Time-Redundancy Error Detection. Tests are triggered by inserting special symb...... hiện toàn bộ
