Book Description
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.

Book Description
This thesis defines a methodology for rapid prototyping custom VLSI processor. The rapid prototyping methodology is based upon the specification of a general purpose architecture customized via microcode to solve unique applications. Since processing requirements will vary, the designer chooses appropriate macrocells from a design library to provide the best hardware support. A high-level language description of the problem is then translated into microcode. The microcode is automatically assembled and designed into a ROM (read-only memory), resulting in a processor customized to solve the given application. By allowing the designer to quickly convert ideas into implementations, the rapid prototyping methodology frees the designer to be creative rather than becoming mired in implementation details. A general purpose VLSI architecture was designed to support the rapid prototyping methodology. The control section of the architecture centers on the micromode ROM (read-only memory) and a microcode sequencer, which provides proper addressing to the ROM. The datapath section (I/O path, registers, and arithmetic hardware) uses the control signals from the ROM to perform the required processing. The datapath macrocells were designed in a bit slice fashion, allowing easy configuration to different data types and widths.

Book Description
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.

Book Description
This report discusses the results of the TI RASSP study efforts to identify a development process consistent with the RASSP program methodology. In this study, we defined the concept of a library based system design approach with in-cycle and out-of-cycle development of library elements. This report discusses this approach and the issues associated with system, hardware, and software design tools, and manufacturing foundry interfaces required to support a library based system development approach. The library based development concept is defined and the modularity and partitioning of a domain specific architecture is discussed. A description of the library elements supporting a library based system design approach is provided. Requirements, issues, and approaches to signal processing system design analyses and tradeoffs, and system simulation and validation are discussed. Data base representation issues, frame- words, and interfaces required to provide a seamless RASSP development environment are identified. Reusable software and library element development issues are addressed. Hardware CAD issues associated with library element development, system analyses, simulation, and validation are discussed. Manufacturing foundry CAD, CIM, design tool interfaces, and test issues are also discussed. A summary of the effort and recommendations for implementation are also included.

Book Description
This document provides, for each of the computer-aided design (CAD) tools in the initial baseline RAASP design environment, a description of its role in the environment, an assessment of strengths and weaknesses, and manufacturer's contact information. This RASSP initial design environment is summarized in Table 1 which specified the tool name, the manufacturer, and a short description of each tool. The detailed description and assessment of each tool comprises the remainder of this document following the introduction.

Book Description
After a brief introduction to low-power VLSI design, the design space of ASIP instruction set architectures (ISAs) is introduced with a special focus on important features for digital signal processing. Based on the degrees of freedom offered by this design space, a consistent ASIP design flow is proposed: this design flow starts with a given application and uses incremental optimization of the ASIP hardware, of ASIP coprocessors and of the ASIP software by using a top-down approach and by applying application-specific modifications on all levels of design hierarchy. A broad range of real-world signal processing applications serves as vehicle to illustrate each design decision and provides a hands-on approach to ASIP design. Finally, two complete case studies demonstrate the feasibility and the efficiency of the proposed methodology and quantitatively evaluate the benefits of ASIPs in an industrial context.
