Download or read book HRT HOODTM A Structured Design Method for Hard Real Time Ada Systems written by A. Burns and published by Elsevier. This book was released on 1995-04-07 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing use of computers for real-time control on board spacecrafts has brought with it a greater emphasis on the development methodology used for such systems. By their nature, spacecraft control computers have to operate unattended for long periods and because of the programmatics of space, systems are subject to a long development cycle. As a result, there are two distinct concerns, the first being that the development approach guarantees functional and timing correctness, the second being that problems, particularly those associated with timing, are considered as early as possible in the spacecraft development life cycle.The European Space Agency has, for a number of years, encouraged the development of software using HOOD. It was thus a natural next step to investigate the incorporation of time within the existing HOOD framework. This has proven to be very beneficial and this book describes the approach developed by the authors for handling Hard Real-Time applications. It describes both the background scheduling theory, provides practical examples of its application to real life problems, and demonstrates how it is used in the various phases of the development of Hard Real-Time systems.

Download or read book Distributed Computer Control Systems 1997 written by I.M. MacLeod and published by Pergamon. This book was released on 1998-01-15 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is increasingly accepted that future dependable, real-time digital computer control systems will have distributed architectures. Advantages of distributed computer control systems include the possibility of composing large systems out of pre-tested components with minimal integration effort, their well-defined fault containment properties and their capacity to make effective use of mass-produced silicon chips. The IFAC Workshop series on Distributed Computer Control Systems (DCCS) focuses on design requirements and fundamental principles encountered in such systems and highlights and traces the growth of key concepts at their various stages of development. Theoretical and application-oriented viewpoints receive equal emphasis. These Workshops also provide an excellent forum for the exchange of information on recent technological advances and practices in the distributed computer control field. The 1997 DCCS Workshop was notable for the attention given to practical implementations of ideas that have been under discussion for decades and maintained the high technical standard set by previous Workshops in the series - the policy of concentrating on a specific topic, inviting a number of key authors and of accepting only a limited number of papers paid dividends.

This book was released on 2012-12-06 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Practitioner's Handbook for Real-Time Analysis: Guide to Rate Monotonic Analysis for Real-Time Systems contains an invaluable collection of quantitative methods that enable real-time system developers to understand, analyze, and predict the timing behavior of many real-time systems. The methods are practical and theoretically sound, and can be used to assess design tradeoffs and to troubleshoot system timing behavior. This collection of methods is called rate monotonic analysis (RMA). The Handbook includes a framework for describing and categorizing the timing aspects of real-time systems, step-by-step techniques for performing timing analysis, numerous examples of real-time situations to which the techniques can be applied, and two case studies. A Practitioner's Handbook for Real-Time Analysis: Guide to Rate Monotonic Analysis for Real-Time Systems has been created to serve as a definitive source of information and a guide for developers as they analyze and design real-time systems using RMA. The Handbook is an excellent reference, and may be used as the text for advanced courses on the subject.

Download or read book Real Time Object Oriented Modeling written by Bran Selic and published by New York ; Toronto : Wiley. This book was released on 1994-05-06 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are you looking for a more effective approach to real-time systems development? Real-Time Object-Oriented Modeling The development of real-time distributed systems is one of the most difficult engineering problems ever faced, taxing the capabilities of traditional real-time software development approaches. Real-Time Object-Oriented Modeling is the first book that brings together, in a single harmonious approach, the power of object-oriented concepts tailored specifically for real-time systems, with an iterative and incremental process based on the use of executable models. Developed by practitioners, the proven methodology described here is becoming a leader in the industry. Using a learn-by-example approach, this book offers: * A single consistent set of graphical modeling concepts, chosen to improve developer effectiveness, which apply uniformly to analysis, design, and implementation. This reduces the learning curve to master the entire method and eliminates expensive discontinuities across different stages of development. * An approach to the object paradigm that is easy to learn and that applies to the construction of reusable architectural design components, not just low-level language elements. This unleashes the true power of the object paradigm. * Techniques for constructing executable models to gain early confidence in specifications and design decisions. * Approaches to project management that deliver the benefits of the object paradigm and executable models.
Download or read book The Difference Engine written by William Gibson and published by Spectra. This book was released on 2011-07-26 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1855: The Industrial Revolution is in full and inexorable swing, powered by steam-driven cybernetic Engines. Charles Babbage perfects his Analytical Engine and the computer age arrives a century ahead of its time. And three extraordinary characters race toward a rendezvous with history—and the future: Sybil Gerard—a fallen woman, politician’s tart, daughter of a Luddite agitator Edward “Leviathan” Mallory—explorer and paleontologist Laurence Oliphant—diplomat, mystic, and spy. Their adventure begins with the discovery of a box of punched Engine cards of unknown origin and purpose. Cards someone wants badly enough to kill for…. Part detective story, part historical thriller, The Difference Engine is the collaborative masterpiece by two of the most acclaimed science fiction authors writing today. Provocative, compelling, intensely imagined, it is a startling extension of Gibson’s and Sterling’s unique visions—and the beginning of movement we know today as “steampunk!”

Download or read book Strategies for Real Time System Specification written by Derek Hatley and published by Addison-Wesley. This book was released on 2013-07-19 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the digital version of the printed book (Copyright © 1987). Here is a casebook, a practical reference, and an indispensable guide for creating a systematic, formal methodology for large, real-time, software-based systems. The book introduces the widely implemented Hatley/Pirbhai methods, a major extension of the DeMarco analysis method describing how external events control the system's operating behavior. The techniques are used in major avionics and electronics companies worldwide, and are automated by most major CASE tools, including TurboCASE/Sys by StructSoft, Inc. Large software-based systems, especially those for real-time applications, require multi-mode operation, direct interaction with a rapidly changing physical environment, and fast response times. In the past, the development of such systems was prone to massive cost and schedule overruns, and to inadequate performance and reliability. Strategies for Real-Time System Specification addresses these problems by integrating a finite-state machine structure into classical analysis methods. The book contains nearly 200 diagrams, many of which illustrate the requirements specification of a flight management system for a major avionics developer.
Download or read book A Review of Ada Tasking written by Alan Burns and published by Springer Science & Business Media. This book was released on 1987-06-24 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ada* is unquestionably one of the most significant programming languages to emerge in the last decade. The manner of its inception and support by the US Department of Defense (DoD) ensures that it will be used extensively for the indefinite future in programming large and complex systems. The growing availability of compilers means that many organisations are already committed to using the language for sizable and significant applications. As a perhaps inevitable result of its design goals, Ada is a "large" language. It has Pascal-like control and type constructs; a mechanism for exception handling; a package structure for information hiding, decomposition and separate compilation; facilities for low-level programming; and a tasking model of concurrency. It is perhaps this last area that has generated most debate, criticism and disagreement. The purpose of this book is to review the tasking model in the light of the extensive analysis and comment which has appeared in the literature. The review is necessarily wide-ranging, including discussion of - Ada as a general purpose concurrent programming language, - Ada as a language for embedded and distributed systems, - implementation issues, with particular reference to distributed systems, - formal semantics, specification and verification, - proposed language modifications. By consolidating this discussion within the confines of a single review, potential users of the tasking facility are enabled to familiarise themselves with all the factors which may impinge upon the performance, reliability and correctness of their software. The book also provides a focus for any debate on modifications to the Ada language, or developments from it.
