Sorting networks are cost-effective multistage interconnection networks with sorting capabilities. AKS Sorting networks sort N keys in C(logN) steps, but the constant C is so high as to render these networks impractical. The fastest Sorting networks designed so far use merge-sorting and sort N keys in O((logN)(logN)) steps. A network that sorts 16 keys in 9 steps was discovered by Van Voorhis. This network is faster than the 10-step merge-sorting network for 16 keys. This suggests that networks that are faster than merge-sorting networks can be designed. It is necessary to bridge the gap between the optimal impractical solutions and the practical solutions. This research aims at achieving this goal via finding a technique for designing faster Sorting networks, i.e. networks that require fewer steps than the corresponding merge-sorting networks. A zero/one case is a sequence of N binary keys. Using zero/one cases to help design Sorting networks, is advantageous since it simplifies the sorting task, and helps track the progress of sorting. To help synthesize and analyze Sorting networks, Batcher developed the software tool Sortnet, which utilizes zero/one cases. With the help of Sortnet, a three-phase technique for designing Sorting networks that are faster than the merge-sorting networks was developed. The technique can also be used to design faster sorting programs in parallel processors. This technique is illustrated with two network designs that are faster than the corresponding merge-sorting designs: an 18-key network using only 11 steps and a 22-key network using only 12 steps.

"This project describes some of the basic characteristics of Neural Networks. It then investigates the existing Hopfield network, used to solve the Traveling Salesman Problem and how it has been modified to sort a list of integers. THis project designs, implements, tests and analyzes three different sorting Neural Networks. These networks are based on the existing bubble sort algorithm and the quick sort algorithm. These three networks are then compared to the modified Hopfield Network. Finally, it addresses a number of software engineering issues related to the design, implementation and tesing of Neural Networks."--Author's abstract.

Biology has inspired electronics from the very beginning: the machines that we now call computers are deeply rooted in biological metaphors. Pioneers such as Alan Turing and John von Neumann openly declared their aim of creating arti?cial machines that could mimic some of the behaviors exhibited by natural organisms. Unfortunately, technology had not progressed enough to allow them to put their ideas into practice. The 1990s saw the introduction of programmable devices, both digital (FP- GAs) and analogue (FPAAs). These devices, by allowing the functionality and the structure of electronic devices to be easily altered, enabled researchers to endow circuits with some of the same versatility exhibited by biological entities and sparked a renaissance in the ?eld of bio-inspired electronics with the birth of what is generally known as evolvable hardware. Eversince,the?eldhasprogressedalongwiththetechnologicalimprovements and has expanded to take into account many di?erent biological processes, from evolution to learning, from development to healing. Of course, the application of these processes to electronic devices is not always straightforward (to say the least!), but rather than being discouraged, researchers in the community have shown remarkable ingenuity, as demostrated by the variety of approaches presented at this conference and included in these proceedings.

This book suggests and describes a number of fast parallel circuits for data/vector processing using FPGA-based hardware accelerators. Three primary areas are covered: searching, sorting, and counting in combinational and iterative networks. These include the application of traditional structures that rely on comparators/swappers as well as alternative networks with a variety of core elements such as adders, logical gates, and look-up tables. The iterative technique discussed in the book enables the sequential reuse of relatively large combinational blocks that execute many parallel operations with small propagation delays. For each type of network discussed, the main focus is on the step-by-step development of the architectures proposed from initial concepts to synthesizable hardware description language specifications. Each type of network is taken through several stages, including modeling the desired functionality in software, the retrieval and automatic conversion of key functions, leading to specifications for optimized hardware modules. The resulting specifications are then synthesized, implemented, and tested in FPGAs using commercial design environments and prototyping boards. The methods proposed can be used in a range of data processing applications, including traditional sorting, the extraction of maximum and minimum subsets from large data sets, communication-time data processing, finding frequently occurring items in a set, and Hamming weight/distance counters/comparators. The book is intended to be a valuable support material for university and industrial engineering courses that involve FPGA-based circuit and system design.

THE CONTEXT OF PARALLEL PROCESSING The field of digital computer architecture has grown explosively in the past two decades. Through a steady stream of experimental research, tool-building efforts, and theoretical studies, the design of an instruction-set architecture, once considered an art, has been transformed into one of the most quantitative branches of computer technology. At the same time, better understanding of various forms of concurrency, from standard pipelining to massive parallelism, and invention of architectural structures to support a reasonably efficient and user-friendly programming model for such systems, has allowed hardware performance to continue its exponential growth. This trend is expected to continue in the near future. This explosive growth, linked with the expectation that performance will continue its exponential rise with each new generation of hardware and that (in stark contrast to software) computer hardware will function correctly as soon as it comes off the assembly line, has its down side. It has led to unprecedented hardware complexity and almost intolerable dev- opment costs. The challenge facing current and future computer designers is to institute simplicity where we now have complexity; to use fundamental theories being developed in this area to gain performance and ease-of-use benefits from simpler circuits; to understand the interplay between technological capabilities and limitations, on the one hand, and design decisions based on user and application requirements on the other.
