Book excerpt: This book collects the research work of leading-edge researchers and practitioners in the areas of analysis, synthesis, design and implementation of real-time systems with applications in various industrial fields. Their works are grouped into six parts, together encompassing twenty chapters. Each part is devoted to a mainstream subject, the chapters therein developing one of the major aspects of real-time system theory, modeling, design, and practical applications. Starting with a general approach in the area of formalization of real-time systems, and setting the foundations for a general systemic theory of those systems, the book covers everything from building modeling frameworks for various types of real-time systems, to verification, and synthesis. Other parts of the book deal with subjects related to tools and applications of these systems. A special part is dedicated to languages used for their modeling and design. The applications presented in the book reveal precious insights into practitioners' secrets.

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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Modeling and Analysis of Real-Time and Embedded Systems with UML and MARTE explains how to apply the complex MARTE standard in practical situations. This approachable reference provides a handy user guide, illustrating with numerous examples how you can use MARTE to design and develop real-time and embedded systems and software. Expert co-authors Bran Selic and Sébastien Gérard lead the team that drafted and maintain the standard and give you the tools you need apply MARTE to overcome the limitations of cyber-physical systems. The functional sophistication required of modern cyber-physical systems has reached a point where traditional code-centric development methods are proving less and less capable of delivering a reliable product in a timely manner. In Modeling and Analysis of Real-Time and Embedded Systems with UML and MARTE, you will learn how to take advantage of modern model-based engineering methods and corresponding industry standards to overcome these limitations. These methods take full advantage of computer-supported automation allowing timely detection of design flaws to reduce engineering risk, leading thereby to better overall product quality and greater productivity. Understand the design rationale behind the MARTE standard needed to take full advantage of its many powerful modeling capabilities Best apply the various MARTE features for the most common use cases encountered in the design of real-time and embedded software Learn how MARTE can be used together with the SysML language for the design of complex cyber-physical systems Discover how MARTE can be used for different kinds of computer-supported engineering analyses to predict key system characteristics early in development Customize MARTE for a specific domain or project

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of both theoretical and pragmatic aspects of resource-allocation and scheduling in multiprocessor and multicore hard-real-time systems. The authors derive new, abstract models of real-time tasks that capture accurately the salient features of real application systems that are to be implemented on multiprocessor platforms, and identify rules for mapping application systems onto the most appropriate models. New run-time multiprocessor scheduling algorithms are presented, which are demonstrably better than those currently used, both in terms of run-time efficiency and tractability of off-line analysis. Readers will benefit from a new design and analysis framework for multiprocessor real-time systems, which will translate into a significantly enhanced ability to provide formally verified, safety-critical real-time systems at a significantly lower cost.

This book was released on 2018-07-05 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful application of software engineering methodologies requires an integrated analysis and design life-cycle in which the various phases flow smoothly 'seamlessly' from analysis through design to implementation. Furthermore, different analysis methodologies often lead to different structuring of the system so that the transition from analysis to design may be awkward depending on the design methodology to be used. This is especially important when object-oriented programming is to be used for implementation when the original specification and perhaps high-level design is non-object oriented. Two approaches to real-time systems analysis which can lead to an object-oriented design are contrasted: (1) modeling the system using structured analysis with real-time extensions which emphasizes data and control flows followed by the abstraction of objects where the operations or methods of the objects correspond to processes in the data flow diagrams and then design in terms of these objects; and (2) modeling the system from the beginning as a set of naturally occurring concurrent entities (objects) each having its own time-behavior defined by a set of states and state-transition rules and seamlessly transforming the analysis models into high-level design models. A new concept of a 'real-time systems-analysis object' is introduced and becomes the basic building block of a series of seamlessly-connected models which progress from the object-oriented real-time systems analysis and design system analysis logical models through the physical architectural models and the high-level design stages. The methodology is appropriate to the overall specification including hardware and software modules. In software modules, the systems analysis objects are transformed into software objects.

Book excerpt: Die Elektronik und die Informatik wird in den nächsten Jahrzehnten einen immer höheren Stellenwert im Bereich der Fahrzeugsicherheit einnehmen. Neue Sensoren zur Umweltwahrnehmung werden die Fahrzeuge in die Lage versetzen angemessen auf die aktuelle Verkehrssituation zu reagieren. Es wird erwartet, dass aktive Sicherheitssysteme, wie beispielsweise die automatische Notbremsung, Fußgänger- und Radfahrererkennung und Funktionen zur Unfallvermeidung, die Anzahl tödlicher Verkehrsunfälle weiter zurückgehen lassen werden. Dabei besteht die Herausforderung darin, die neuen Sicherheitsfunktionen in ein System zu integrieren, dass bereits heute hochkomplex und vernetzt ist. Entstehen werden Echtzeitsysteme, die aus hochintegrierten Subsystemen bestehen werden. In dieser Dissertation werden Methoden entwickelt, um die Auslegung derartiger Steuergeräte in frühen Entwicklungsphasen abzusichern. Mithilfe von Modelltransformationen sowie simulativer und formaler Methoden werden verschiedene Architekturkonzepte aus den Perspektiven eﬀektiver Umfeldwahrnehmung, funktionaler Sicherheit und Echtzeitfähigkeit betrachtet und bewertet. Von besonderer Bedeutung sind hierbei die Echtzeiteigenschaften der Softwareanteile der Sicherheitsfunktionen. Alle entwickelten Methoden wurden im Rahmen einer Forschungskooperation zwischen der Universität Erlangen-Nürnberg und der AUDI AG angewendet. Folgende Erkenntnisse konnten unter Anderem gewonnen werden: • Die Fusion von Objektlisten verschiedenartiger Sensoren ist aus Kosten-Nutzen-Sicht zu bevorzugen. • Modellbasierte Sicherheitsanalysen bieten sich insbesondere in frühen Entwicklungsphasen an, den Entwicklungsprozess zu unterstützen. • Für die Echtzeitanalyse von Steuergeräten sind exakte Algorithmen erforderlich, die in der Lage sind die kritischen Systemzustände zu visualisieren. • Die Simulation der Softwaretasks ist ein wichtiger Bestandteil der Analyse und ist erforderlich, um die dynamischen Effekte des Systems zu verstehen, sowie die Relevanz der kritischen Systemzustände einschätzen zu können. • Der Ansatz der modellgetriebenen Entwicklung ist besonders praktikabel in frühen Phasen der Systementwicklung, wenn man die Verallgemeinerung der Erkenntnisse unter Berücksichtigung des Abstraktionsgrades der Systemmodelle und der Eingabeparametermodelle durchführt. Durch die durchgeführten Analysen wurden Jahre vor der Serienproduktion, und Monate bevor erste Entwicklungsmuster zur Verfügung standen, an verschiedenen Stellen Engpässe in der Leistungsfähigkeit der Architekturkonzepte gefunden. Aufgrund der guten Zusammenarbeit zwischen OEM, Lieferant und Wissenschaft wurden neue Entwicklungsprozesse ins Leben gerufen und implementiert. Sowohl momentane als auch zukünftige Sicherheitssysteme proﬁtieren von den entwickelten Methoden und werden die Basis bieten können um effiziente und effektive Funktionen der Fahrzeugsicherheit umsetzen zu können.
