Distributed Real Time Systems

Distributed Real-Time Systems

This classroom-tested textbook describes the design and implementation of software for distributed real-time systems, using a bottom-up approach. The text addresses common challenges faced in software projects involving real-time systems, and presents a novel method for simply and effectively performing all of the software engineering steps. Each chapter opens with a discussion of the core concepts, together with a review of the relevant methods and available software. This is then followed with a description of the implementation of the concepts in a sample kernel, complete with executable code. Topics and features: introduces the fundamentals of real-time systems, including real-time architecture and distributed real-time systems; presents a focus on the real-time operating system, covering the concepts of task, memory, and input/output management; provides a detailed step-by-step construction of a real-time operating system kernel, which is then used to test various higher level implementations; describes periodic and aperiodic scheduling, resource management, and distributed scheduling; reviews the process of application design from high-level design methods to low-level details of design and implementation; surveys real-time programming languages and fault tolerance techniques; includes end-of-chapter review questions, extensive C code, numerous examples, and a case study implementing the methods in real-world applications; supplies additional material at an associated website. Requiring only a basic background in computer architecture and operating systems, this practically-oriented work is an invaluable study aid for senior undergraduate and graduate-level students of electrical and computer engineering, and computer science. The text will also serve as a useful general reference for researchers interested in real-time systems.

Distributed Real-Time Systems

Distributed real-time systems (DRTSs) are used in a wide range of applications, including command and control systems, flight control systems, robotics, patient monitoring systems, and many others. This volume provides an overview of various systematic approaches to the testing and debugging of DRTSs—tasks that typically consume 50% to 70% of a new system's development costs. Distributed Real-Time Systems covers both the theoretical and practical issues involved in monitoring, visualization, and analysis methodology for verifying and debugging DRTSs. It describes in detail how to overcome timing verification difficulties and improve system performance and reliability. Complete with many carefully worked-out examples, as well as dozens of illustrations, this timely and accessible work Explains real-world debugging approaches—proposed or tested—using static analysis or dynamic analysis with or without monitoring Features step-by-step instructions for design implementation in hardware and software, detecting timing errors and their causes, graphical debugging methods, and more Covers numerous analytical techniques, including timed Petri nets, temporal logic, timed state transition systems, timed process algebra, and synchronous programming languages Makes distributed systems analysis accessible through examples such as a distributed telephone switching system and a fault-tolerant distributed system Reviews many relevant professional papers and current research work The joint product of four leaders in the field, Distributed Real-Time Systems is an important text and reference for electrical and software engineers, graduate students, and anyone involved in computer and data processing technology.
