This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years, the demand for high speed Digital Signal Proces sing (DSP) has increased dramatically. New applications in real-time image processing, satellite communications, radar signal processing, pattern recogni tion, and real-time signal detection and estimation require major improvements at several levels; algorithmic, architectural, and implementation. These perfor mance requirements can be achieved by employing parallel processing at all levels. Very Large Scale Integration (VLSI) technology supports and provides a good avenue for parallelism. Parallelism offers efficient sohitions to several problems which can arise in VLSI DSP architectures such as: 1. Intermediate data communication and routing: several DSP algorithms, such as FFT, involve excessive data routing and reordering. Parallelism is an efficient mechanism to minimize the silicon cost and speed up the pro cessing time of the intermediate middle stages. 2. Complex DSP applications: the required computation is almost doubled. Parallelism will allow two similar channels processing at the same time. The communication between the two channels has to be minimized. 3. Applicatilm specific systems: this emerging approach should achieve real-time performance in a cost-effective way. 4. Testability and fault tolerance: reliability has become a required feature in most of DSP systems. To achieve such property, the involved time overhead is significant. Parallelism may be the solution to maintain ac ceptable speed performance.

This book was released on 2012-09-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite five decades of research, parallel computing remains an exotic, frontier technology on the fringes of mainstream computing. Its much-heralded triumph over sequential computing has yet to materialize. This is in spite of the fact that the processing needs of many signal processing applications continue to eclipse the capabilities of sequential computing. The culprit is largely the software development environment. Fundamental shortcomings in the development environment of many parallel computer architectures thwart the adoption of parallel computing. Foremost, parallel computing has no unifying model to accurately predict the execution time of algorithms on parallel architectures. Cost and scarce programming resources prohibit deploying multiple algorithms and partitioning strategies in an attempt to find the fastest solution. As a consequence, algorithm design is largely an intuitive art form dominated by practitioners who specialize in a particular computer architecture. This, coupled with the fact that parallel computer architectures rarely last more than a couple of years, makes for a complex and challenging design environment. To navigate this environment, algorithm designers need a road map, a detailed procedure they can use to efficiently develop high performance, portable parallel algorithms. The focus of this book is to draw such a road map. The Parallel Algorithm Synthesis Procedure can be used to design reusable building blocks of adaptable, scalable software modules from which high performance signal processing applications can be constructed. The hallmark of the procedure is a semi-systematic process for introducing parameters to control the partitioning and scheduling of computation and communication. This facilitates the tailoring of software modules to exploit different configurations of multiple processors, multiple floating-point units, and hierarchical memories. To showcase the efficacy of this procedure, the book presents three case studies requiring various degrees of optimization for parallel execution.

Book excerpt: The Burg algorithm is a widely applied and extensively studied signal processing procedure having a structure typical of a class of important batch signal processing algorithms. Its implementation and performance on four different parallel machines were reported in the 1990 Journal of Parallel and Distributed Computing Special Issue on Massively Parallel Computation. The machines were: the Intel iPSC/2, the Denelcor HEP, the NASA/Goodyear MPP, and the Cray X-MP/48. The objective of the work reported here was to extend that study to two new parallel machines: the nCUBE 2 and the MasPar MP-1. These computers are related to the distributed memory systems above (i.e., the iPSC and the MPP, respectively), but use newer technology. In addition to achieving significant performance gains on the new machines compared to machines in the same architectural class, we found that the original study underestimated the scaleability of the algorithm. That is, the algorithm maps efficiently to small-scale as well as large-scale computers, including both SIMD and MIMD distributed memory systems. Improvements in the parallel algorithm are highlighted. Of special import is the use of appropriate performance metrics and performance visualization to characterize the parallelism of the algorithm and lend insight toward understanding and evaluating its performance. 14 refs., 9 figs.

Download or read book Microprocessor-Based Parallel Architecture for Reliable Digital Signal Processing Systems written by Alan D. George and published by CRC Press. This book was released on 2018-01-18 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a distributed multiprocessor architecture that is faster, more versatile, and more reliable than traditional single-processor architectures. It also describes a simulation technique that provides a highly accurate means for building a prototype system in software. The system prototype is studied and analyzed using such DSP applications as digital filtering and fast Fourier transforms. The code is included as well, which allows others to build software prototypes for their own research systems. The design presented in Microprocessor-Based Parallel Architecture for Reliable Digital Signal Processing Systems introduces the concept of a dual-mode architecture that allows users a dynamic choice between either a conventional or fault-tolerant system as application requirements dictate. This volume is a "must have" for all professionals in digital signal processing, parallel and distributed computer architecture, and fault-tolerant computing.

This book was released on 2012-12-06 with total page 717 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical linear algebra, digital signal processing, and parallel algorithms are three disciplines with a great deal of activity in the last few years. The interaction between them has been growing to a level that merits an Advanced Study Institute dedicated to the three areas together. This volume gives an account of the main results in this interdisciplinary field. The following topics emerged as major themes of the meeting: - Singular value and eigenvalue decompositions, including applications, - Toeplitz matrices, including special algorithms and architectures, - Recursive least squares in linear algebra, digital signal processing and control, - Updating and downdating techniques in linear algebra and signal processing, - Stability and sensitivity analysis of special recursive least squares problems, - Special architectures for linear algebra and signal processing. This book contains tutorials on these topics given by leading scientists in each of the three areas. A consider- able number of new research results are presented in contributed papers. The tutorials and papers will be of value to anyone interested in the three disciplines.

Jamali and published by . This book was released on 1993 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of today's problems in signal processing is the identification of direction-of-arrival (DOA) for multiple broad-band sources. Many algorithms have been proposed in the literature, however, the algorithms are highly complex and require a lot of computing power. New technologies in the past two decades have decreased the cost of digital hardware, and its speed has increased to such an extent that digital signal processing has replaced a great deal of analog signal processing. This thesis presents a digital-domain parallel-pipelined architecture capable of computing the DOA of multiple broad-band sources in real-time. Broad-Band Signal-Subspace Spatial-Spectrum (BASS-ALE) Estimation algorithm has been selected for DOA estimation and has been simulated and verified through computer software programs. The BASS-ALE algorithm has been modified and parallelized. The parallel algorithm has been mapped on an architecture which is suitable for real-time computation.
