Application Specific Processors is written for use by engineers who are developing specialized systems (application specific systems). Traditionally, most high performance signal processors have been realized with application specific processors. The explanation is that application specific processors can be tailored to exactly match the (usually very demanding) application requirements. The result is that no `processing power' is wasted for unnecessary capabilities and maximum performance is achieved. A disadvantage is that such processors have been expensive to design since each is a unique design that is customized to the specific application. In the last decade, computer-aided design systems have been developed to facilitate the development of application specific integrated circuits. The success of such ASIC CAD systems suggests that it should be possible to streamline the process of application specific processor design. Application Specific Processors consists of eight chapters which provide a mixture of techniques and examples that relate to application specific processing. The inclusion of techniques is expected to suggest additional research and to assist those who are faced with the requirement to implement efficient application specific processors. The examples illustrate the application of the concepts and demonstrate the efficiency that can be achieved via application specific processors. The chapters were written by members and former members of the application specific processing group at the University of Texas at Austin. The first five chapters relate to specific arithmetic which often is the key to achieving high performance in application specific processors. The next two chapters focus on signal processing systems, and the final chapter examines the interconnection of possibly disparate elements to create systems.

Rapid Prototyping of Application Specific Signal Processors presents leading-edge research that focuses on design methodology, infrastructure support and scalable architectures developed by the 150 million dollar DARPA United States Department of Defense RASSP Program. The contributions to this edited work include an introductory overview chapter that explains the origin, concepts and status of this effort. The RASSP Program is a multi-year DARPA/Tri-Service initiative intended to dramatically improve the process by which complex digital systems, particularly embedded signal processors, are designed, manufactured, upgraded and supported. This program was originally driven by military applications for signal processing. The requirements of military applications for real-time signal processing are typically more demanding than those of commercial applications, but the time gap between technology employed in advanced military prototypes and commercial products is narrowing rapidly. The research on methodologies, infrastructure and architectures presented in this book is applicable to commercial signal processing systems that are in design now, or will be developed before the end of the decade. Rapid Prototyping of Application Specific Signal Processors is a valuable reference for developers of embedded digital systems, particularly systems engineers for signal processing systems (such as digital TV, biomedical image processing systems and telecommunications) and for military contractors who are developing signal processing systems. This book will also be of interest to managers who are charged with responsibility for creating and maintaining environments and infrastructures for developing large embedded digital systems. The chief value for managers will be the defining of methods and processes that reduce development time and cost.

Floating-point computer arithmetic units are used for modern-day computers for 2D/3D graphic and scientific applications due to their wider dynamic range than a fixed-point number system with the same word-length. However, the floating-point arithmetic unit has larger area, power consumption, and latency than a fixed-point arithmetic unit. It has become a big issue in modern low-power processors due to their limited power and performance margins. Therefore, fused architectures have been developed to improve floating-point operations. This dissertation introduces new improved fused architectures for add-subtract, sum-of-squares, and magnitude operations for graphics, scientific, and signal processing. A low-power dual-path fused floating-point add-subtract unit is introduced and compared with previous fused add-subtract units such as the single path and the high-speed dual-path fused add-subtract unit. The high-speed dual-path fused add-subtract unit has less latency compared with the single-path unit at a cost of large power consumption. To reduce the power consumption, an alternative dual-path architecture is applied to the fused add-subtract unit. The significand addition, subtraction and round units are performed after the far/close path. The power consumption of the proposed design is lower than the high-speed dual-path fused add-subtract unit at a cost in latency; however, the proposed fused unit is faster than the single-path fused unit. High-performance and low-power floating-point fused architectures for a two-term sum-of-squares computation are introduced and compared with discrete units. The fused architectures include pre/post-alignment, partial carry-sum width, and enhanced rounding. The fused floating-point sum-of-squares units with the post-alignment, 26 bit partial carry-sum width, and enhanced rounding system have less power-consumption, area, and latency compared with discrete parallel dot-product and sum-of-squares units. Hardware tradeoffs are presented between the fused designs in terms of power consumption, area, and latency. For example, the enhanced rounding processing reduces latency with a moderate cost of increased power consumption and area. A new type of fused architecture for magnitude computation with less power consumption, area, and latency than conventional discrete floating-point units is proposed. Compared with the discrete parallel magnitude unit realized with conventional floating-point squarers, an adder, and a square-root unit, the fused floating-point magnitude unit has less area, latency, and power consumption. The new design includes new designs for enhanced exponent, compound add/round, and normalization units. In addition, a pipelined structure for the fused magnitude unit is shown.

Focusing on an approach of solving rigorous problems and learning how to prove, this volume is concentrated on two specific content themes, elementary number theory and algebraic polynomials. The benefit to readers who are moving from calculus to more abstract mathematics is to acquire the ability to understand proofs through use of the book and the multitude of proofs and problems that will be covered throughout. This book is meant to be a transitional precursor to more complex topics in analysis, advanced number theory, and abstract algebra. To achieve the goal of conceptual understanding, a large number of problems and examples will be interspersed through every chapter. The problems are always presented in a multi-step and often very challenging, requiring the reader to think about proofs, counter-examples, and conjectures. Beyond the undergraduate mathematics student audience, the text can also offer a rigorous treatment of mathematics content (numbers and algebra) for high-achieving high school students. Furthermore, prospective teachers will add to the breadth of the audience as math education majors, will understand more thoroughly methods of proof, and will add to the depth of their mathematical knowledge. In the past, PNA has been taught in a "problem solving in middle school” course (twice), to a quite advanced high school students course (three semesters), and three times as a secondary resource for a course for future high school teachers. PNA is suitable for secondary math teachers who look for material to encourage and motivate more high achieving students.
