Download or read book Real Time UML Workshop for Embedded Systems written by Bruce Powel Douglass and published by Elsevier. This book was released on 2011-04-01 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical new book provides much-needed, practical, hands-on experience capturing analysis and design in UML. It holds the hands of engineers making the difficult leap from developing in C to the higher-level and more robust Unified Modeling Language, thereby supporting professional development for engineers looking to broaden their skill-sets in order to become more saleable in the job market. It provides a laboratory environment through a series of progressively more complex exercises that act as building blocks, illustrating the various aspects of UML and its application to real-time and embedded systems. With its focus on gaining proficiency, it goes a significant step beyond basic UML overviews, providing both comprehensive methodology and the best level of supporting exercises available on the market. Each exercise has a matching solution which is thoroughly explained step-by-step in the back of the book. The techniques used to solve these problems come from the author's decades of experience designing and constructing real-time systems. After the exercises have been successfully completed, the book will act as a desk reference for engineers, reminding them of how many of the problems they face in their designs can be solved. - Tutorial style text with keen focus on in-depth presentation and solution of real-world example problems - Highly popular, respected and experienced author

Download or read book Specification and Design Methodology for Real Time Embedded Systems written by Randall S. Janka and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book is an essential reading for advanced undergraduates and graduate students in a wide range of disciplines impacted by embedded computing and software. Its conceptual clarity, the style of explanations and the examples make the abstract concepts accessible for a wide audience." Janos Sztipanovits, Director E. Bronson Ingram Distinguished Professor of Engineering Institute for Software Integrated Systems Vanderbilt University Real-Time Systems focuses on hard real-time systems, which are computing systems that must meet their temporal specification in all anticipated load and fault scenarios. The book stresses the system aspects of distributed real-time applications, treating the issues of real-time, distribution and fault-tolerance from an integral point of view. A unique cross-fertilization of ideas and concepts between the academic and industrial worlds has led to the inclusion of many insightful examples from industry to explain the fundamental scientific concepts in a real-world setting. Compared to the first edition, new developments in complexity management, energy and power management, dependability, security, and the internet of things, are addressed. The book is written as a standard textbook for a high-level undergraduate or graduate course on real-time embedded systems or cyber-physical systems. Its practical approach to solving real-time problems, along with numerous summary exercises, makes it an excellent choice for researchers and practitioners alike.

Download or read book Analysis and Synthesis of Distributed Real Time Embedded Systems written by Paul Pop and published by Springer Science & Business Media. This book was released on 2004-12-21 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embedded computer systems are now everywhere: from alarm clocks to PDAs, from mobile phones to cars, almost all the devices we use are controlled by embedded computers. An important class of embedded computer systems is that of hard real-time systems, which have to fulfill strict timing requirements. As real-time systems become more complex, they are often implemented using distributed heterogeneous architectures. Analysis and Synthesis of Distributed Real-Time Embedded Systems addresses the design of real-time applications implemented using distributed heterogeneous architectures. The systems are heterogeneous not only in terms of hardware components, but also in terms of communication protocols and scheduling policies. Regarding this last aspect, time-driven and event-driven systems, as well as a combination of the two, are considered. Such systems are used in many application areas like automotive electronics, real-time multimedia, avionics, medical equipment, and factory systems. The proposed analysis and synthesis techniques derive optimized implementations that fulfill the imposed design constraints. An important part of the implementation process is the synthesis of the communication infrastructure, which has a significant impact on the overall system performance and cost. Analysis and Synthesis of Distributed Real-Time Embedded Systems considers the mapping and scheduling tasks within an incremental design process. To reduce the time-to-market of products, the design of real-time systems seldom starts from scratch. Typically, designers start from an already existing system, running certain applications, and the design problem is to implement new functionality on top of this system. Supporting such an incremental design process provides a high degree of flexibility, and can result in important reductions of design costs. STRONGAnalysis and Synthesis of Distributed Real-Time Embedded Systems will be of interest to advanced undergraduates, graduate students, researchers and designers involved in the field of embedded systems.
