Specification And Design Methodology For Real Time Embedded Systems

Specification and design methodology has seen significant growth as a research area over the last decade, tracking but lagging behind VLSI design technology in general and the CAD industry in particular. The commercial rush to market tries to leverage existing technology which fuels CAD design tool development. Paralleling this is very active basic and applied research to investigate and move forward rational and effective methodologies for accomplishing digital design, especially in the field of hardware/software codesign. It is this close relationship between industry and academia that makes close cooperation between researchers and practitioners so important-and monographs like this that combine both abstract concept and pragmatic implementation deftly bridge this often gaping chasm. It was at the IEEE/ACM Eighth International Symposium on Hardware/Software Codesign where I met the author of this monograph, Dr. Randall Janka, who was presenting some of his recent dissertation research results on specification and design methodology, or as he has so succinctly defined this sometimes ambiguous concept, "the tools and rules." Where so many codesign researchers are trying to prove out different aspects of codesign and using toy applications to do so, Dr. Janka had developed a complete specification and design methodology and prototyped the infrastructure-and proven its viability, utility, and effectiveness using a demanding real-world application of a real-time synthetic aperture radar imaging processor that was implemented with embedded parallel processors.

Offers a comprehensive overview of real-time system design procedures and techniques for industrial and manufacturing processes plus an introduction to MCSE methodology. Includes case studies and end-of-chapter summaries of the key points covered.

This is the first book on embedded systems to offer a unified approach to hardware and software specification and design issues -- and the first to outline a new specify-explore-refine paradigm that is presently being used in industry in an ad-hoc manner, but until now has not been formally described. The book addresses the system design methodology from conceptualization to manufacturing using this new paradigm, and shows how this methodology can result in 10x improvement in productivity. Addresses two of the most significant topics in the design of digital systems -- executable system specification and a methodology for system partitioning and refinement into system-level components. Covers models and architectures; specification languages; a specification example; translation to VHDL; system partitioning; design quality estimation; specification refinement into synthesizable models; and system-design methodology and environment. Contains a complete specification of a model product (telephone answering machine), and demonstrates how to write the specification from an English description. For RISC design methodologists and VHDL methodologists; and CAD software developers.

As almost no other technology, embedded systems is an essential element of many innovations in automotive engineering. New functions and improvements of already existing functions, as well as the compliance with traffic regulations and customer requirements, have only become possible by the increasing use of electronic systems, especially in the fields of driving, safety, reliability, and functionality. Along with the functionalities that increase in number and have to cooperate, the complexity of the entire system will increase. Synergy effects resulting from distributed application functionalities via several electronic control devies, exchanging information through the network brings about more complex system architectures with many different sub-networks, operating with different velocities and different protocol implementations. To manage the increasing complexity of these systems, a deterministic behaviour of the control units and the communication network must be provided for, in particular when dealing with a distributed functionality. From Specification to Embedded Systems Application documents recent approaches and results presented at the International Embedded Systems Symposium (IESS 2005), which was held in August 2005 in Manaus (Brazil) and sponsored by the International Federation for Information Processing (IFIP). The topics which have been chosen for this working conference are very timely: design methodology, modeling, specification, software synthesis, power management, formal verification, testing, network, communication systems, distributed control systems, resource management and special aspects in system design.

This book is the latest contribution to the Chip Design Languages series and it consists of selected papers presented at the Forum on Specifications and Design Languages (FDL'07), in September 2007. The book represents the state-of-the-art in research and practice, and it identifies new research directions. It highlights the role of specification and modelling languages, and presents practical experiences with specification and modelling languages

The complexity of most real-time and embedded systems often exceeds that of other types of systems since, in addition to the usual spectrum of problems inherent in software, they need to deal with the complexities of the physical world. That world—as the proverbial Mr. Murphy tells us—is an unpredictable and often unfriendly place. Consequently, there is a very strong motivation to investigate and apply advanced design methods and technologies that could simplify and improve the reliability of real-time software design and implementation. As a result, from the first versions of UML issued in the mid 1990’s, designers of embedded and real-time systems have taken to UML with vigour and enthusiasm. However, the dream of a complete, model-driven design flow from specification through automated, optimised code generation, has been difficult to realise without some key improvements in UML semantics and syntax, specifically targeted to the real-time systems problem. With the enhancements in UML that have been proposed and are near standardisation with UML 2. 0, many of these improvements have been made. In the Spring of 2003, adoption of a formalised UML 2. 0 specification by the members of the Object Management Group (OMG) seems very close. It is therefore very appropriate to review the status of UML as a set of notations for embedded real-time systems - both the state of the art and best practices achieved up to this time with UML of previous generations - and where the changes embodied in the 2.

As electronic technology reaches the point where complex systems can be integrated on a single chip, and higher degrees of performance can be achieved at lower costs, designers must devise new ways to undertake the laborious task of coping with the numerous, and non-trivial, problems that arise during the conception of such systems. On the other hand, shorter design cycles (so that electronic products can fit into shrinking market windows) put companies, and consequently designers, under pressure in a race to obtain reliable products in the minimum period of time. New methodologies, supported by automation and abstraction, have appeared which have been crucial in making it possible for system designers to take over the traditional electronic design process and embedded systems is one of the fields that these methodologies are mainly targeting. The inherent complexity of these systems, with hardware and software components that usually execute concurrently, and the very tight cost and performance constraints, make them specially suitable to introduce higher levels of abstraction and automation, so as to allow the designer to better tackle the many problems that appear during their design. Advanced Techniques for Embedded Systems Design and Test is a comprehensive book presenting recent developments in methodologies and tools for the specification, synthesis, verification, and test of embedded systems, characterized by the use of high-level languages as a road to productivity. Each specific part of the design process, from specification through to test, is looked at with a constant emphasis on behavioral methodologies. Advanced Techniques for Embedded Systems Design and Test is essential reading for all researchers in the design and test communities as well as system designers and CAD tools developers.
