Book Description
The size of the VLSI circuit is increasing at a very rapid pace, and soon the sequential algorithms running on a uniprocessor will be inadequate to handle such large circuits. Parallel processing can be used to reduce the computation time considerably with almost no degradation in the quality. Most of the parallel algorithms developed for VLSI CAD applications, however, are designed for one specific parallel architecture. As a result, considerable effort and expense are needed to port them to different parallel machines. The ongoing ProperCAD project at the University of Illinois offers a bright solution to that problem by allowing the user to develop parallel algorithms on the top of a portable framework such that the programs developed will run unchanged on a variety of parallel machines, both shared and distributed memory machines. In this thesis, parallel algorithms for combinational logic synthesis using two approaches are developed: (1) the Transduction method, which uses the concept of a set of permissible functions to perform various logic transformations to reduce the size of logic circuit, and (2) the MIS approach, which uses algebraic factoring and node simplification for the purpose of logic minimization. The parallel algorithms developed in this thesis offer three major contributions. First, the parallel algorithms use an asynchronous, message-driven computing model with no synchronizing barriers separating phases of parallel computation. Second, these algorithms are portable across a wide variety of parallel architectures, shared memory machines such as Encore Multimax and Sequent Symmetry, distributed memory machines such as Intel/860, and networks of workstations. Finally, these algorithms are built around well defined sequential algorithm interfaces, so that the parallel algorithms can benefit from the future improvements and expansions of the sequential algorithms. Very large circuits, however, can not he handled as a whole by any synthesis algorithm. Those circuits are partitioned, and then the partitions are synthesized independently in parallel. A parallel synthesis system based on the partitioning approach is also described in this thesis.

Book Description
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 Description
Logic Synthesis and Verification Algorithms is a textbook designed for courses on VLSI Logic Synthesis and Verification, Design Automation, CAD and advanced level discrete mathematics. It also serves as a basic reference work in design automation for both professionals and students. Logic Synthesis and Verification Algorithms is about the theoretical underpinnings of VLSI (Very Large Scale Integrated Circuits). It combines and integrates modern developments in logic synthesis and formal verification with the more traditional matter of Switching and Finite Automata Theory. The book also provides background material on Boolean algebra and discrete mathematics. A unique feature of this text is the large collection of solved problems. Throughout the text the algorithms covered are the subject of one or more problems based on the use of available synthesis programs.

Book Description
This book is an introduction to the field of parallel algorithms and the underpinning techniques to realize the parallelization. The emphasis is on designing algorithms within the timeless and abstracted context of a high-level programming language. The focus of the presentation is on practical applications of the algorithm design using different models of parallel computation. Each model is illustrated by providing an adequate number of algorithms to solve some problems that quite often arise in many applications in science and engineering.The book is largely self-contained, presuming no special knowledge of parallel computers or particular mathematics. In addition, the solutions to all exercises are included at the end of each chapter.The book is intended as a text in the field of the design and analysis of parallel algorithms. It includes adequate material for a course in parallel algorithms at both undergraduate and graduate levels.
