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.

"Real-time Systems’ Quality of Service" examines the attainability of efficiency, economy, and ease of use, which make up the quality of service of technologically advanced products. "Real-time Systems’ Quality of Service" reviews the state of the art in quality of service evaluation for real-time systems. It gives a classification of the relevant parameters for quality of service evaluation and also determines the critical points in the design and development process of real-time systems – where performance criteria should be applied or checked. Then, software development and certification standards are assessed, and finally the authors elaborate on how the suggested criteria should be applied to the design, development, and certification process of real-time systems. "Real-time Systems’ Quality of Service" will guide researchers and postgraduates in embedded and real-time systems through the process of introducing quality of service parameters into real-time systems.
This volume contains the lectures given in honor to Georg Färber as tribute to his contributions in the area of real-time and embedded systems. The chapters of many leading scientists cover a wide range of aspects, like robot or automotive vision systems or medical aspects.
Real-time systems are computer systems that are designed to respond to external events within a specified time constraint. These systems are used in a variety of applications, including control systems, communication systems, multimedia systems, and embedded systems. Real-time systems must be able to respond to events in a timely and deterministic manner, meaning that the response time must be guaranteed and consistent. One of the main challenges in designing real-time systems is ensuring that they are predictable and reliable. Real-time systems must be able to handle a wide range of input conditions, from normal operation to extreme conditions, without crashing or failing to meet their deadlines. This requires careful design and implementation, as well as testing and verification to ensure that the system behaves as intended. Real-time systems often have unique requirements that differ from those of traditional computer systems. For example, real-time systems may need to operate in harsh environments, such as extreme temperatures or high radiation levels. They may also need to communicate with other systems in real-time, which requires low-latency communication protocols and high bandwidth. In addition to these technical challenges, there are also legal and ethical considerations when designing real-time systems. For example, systems used in safety-critical applications, such as medical devices or transportation systems, must meet strict regulatory requirements and undergo rigorous testing and certification processes. Overall, the design and implementation of real-time systems is a complex and challenging task that requires a deep understanding of the system's requirements, its environment, and the technologies available. In this textbook, we will explore the key concepts, principles, and techniques used in the design and analysis of real-time systems. We will cover topics such as scheduling, synchronization, communication, fault-tolerance, and performance analysis, and provide examples and case studies to illustrate these concepts. By the end of this book, readers will have a solid understanding of real-time systems and the skills needed to design and implement them effectively.
"This book is a comprehensive text for the design of safety critical, hard real-time embedded systems. It offers a splendid example for the balanced, integrated treatment of systems and software engineering, helping readers tackle the hardest problems of advanced real-time system design, such as determinism, compositionality, timing and fault management. 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 Second Edition, new developments in communication standards for time-sensitive networks, such as TSN and Time-Triggered Ethernet are addressed. Furthermore, this edition includes a new chapter on real-time aspects in cloud and fog computing. 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.
This book presents high-quality original contributions on new software engineering models, approaches, methods, and tools and their evaluation in the context of defence and security applications. In addition, important business and economic aspects are discussed, with a particular focus on cost/benefit analysis, new business models, organizational evolution, and business intelligence systems. The contents are based on presentations delivered at SEDA 2018, the 6th International Conference in Software Engineering for Defence Applications, which was held in Rome, Italy, in June 2018. This conference series represents a targeted response to the growing need for research that reports and debates the practical implications of software engineering within the defence environment and also for software performance evaluation in real settings through controlled experiments as well as case and field studies. The book will appeal to all with an interest in modeling, managing, and implementing defence-related software development products and processes in a structured and supportable way.
IMPORTANT: This is a rebadged version of Real-time Operating Systems, Book 1, The Theory which (so far) has received eleven 5-star, one 4-star and one 3-star reviews.This book deals with the fundamentals of operating systems for use in real-time embedded systems. It is aimed at those who wish to develop RTOS-based designs, using either commercial or free products. It does not set out to give you a knowledge to design an RTOS; leave that to the specialists. The target readership includes:- Students.- Engineers, scientists and mathematicians moving into software systems.- Professional and experienced software engineers entering the embedded field.- Programmers having little or no formal education in the underlying principles of software-based real-time systems.The material covers the key 'nuts and bolts' of RTOS structures and usage (as you would expect, of course). In many cases it shows how these are handled by practical real-time operating systems. It also places great emphasises on ways to structure the application software so that it can be effectively implemented using an RTOS. After studying this even the absolute beginner will see that it isn't particularly difficult to implement RTOS-based designs and should be confident to take on such work.
This volume contains the 37 papers presented at the 9th International Con- rence on Real-Time and Embedded Computing Systems and Applications (RT- CSA 2003). RTCSA is an international conference organized for scientists and researchers from both academia and industry to hold intensive discussions on advancing technologies topics on real-time systems, embedded systems, ubiq- tous/pervasive computing, and related topics. RTCSA 2003 was held at the Department of Electrical Engineering of National Cheng Kung University in Taiwan. Paper submissions were well distributed over the various aspects of real-time computing and embedded system technologies. There were more than 100 participants from all over the world. The papers, including 28 regular papers and 9 short papers are grouped into thecategoriesofscheduling,networkingandcommunication,embeddedsystems, pervasive/ubiquitous computing, systems and architectures, resource mana- ment, ?le systems and databases, performance analysis, and tools and de- lopment. The grouping is basically in accordance with the conference program. Earlier versions of these papers were published in the conference proceedings. However, some papers in this volume have been modi?ed or improved by the authors, in various aspects, based on comments and feedback received at the conference. It is our sincere hope that researchers and developers will bene?t from these papers. We would like to thank all the authors of the papers for their contribution. We thank the members of the program committee and the reviewers for their excellent work in evaluating the submissions. We are also very grateful to all the members of the organizing committees for their help, guidance and support.
The introduction of the microprocessor in computer and system engineering has motivated the development of many new concepts and has simplified the design of many modern industrial systems. During the first decade of their life. microprocessors have shown a tremendous evolution in all possible directions (technology. power. functionality. I/O handling. etc). Of course putting the microprocessors and their environmental devices into properly operating systems is a complex and difficult task requiring high skills for melding and integrating hardware. and systemic components. software This book was motivated by the editors' feeling that a cohesive reference is needed providing a good coverage of modern industrial applications of microprocessor-based real time control, together with latest advanced methodological issues. Unavoidably a single volume cannot be exhaustive. but the present book contains a sufficient number of important real-time applications. The book is divided in two sections. Section I deals with general hardware. software and systemic topics. and involves six chapters. Chapter 1. by Gupta and Toong. presents an overview of the development of microprocessors during their first twelve years of existence. Chapter 2. by Dasgupta. deals with a number of system software concepts for real time microprocessor-based systems (task scheduling. memory management. input-output aspects. programming language reqUirements.
