Book Synopsis Synchronization in Real-Time Systems by : Ragunathan Rajkumar
Download or read book Synchronization in Real-Time Systems written by Ragunathan Rajkumar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time computing systems are vital to a wide range of applications. For example, they are used in the control of nuclear reactors and automated manufacturing facilities, in controlling and tracking air traffic, and in communication systems. In recent years, real-time systems have also grown larger and become more critical. For instance, advanced aircraft such as the space shuttle must depend heavily on computer sys tems [Carlow 84]. The centralized control of manufacturing facilities and assembly plants operated by robots are other examples at the heart of which lie embedded real-time systems. Military defense systems deployed in the air, on the ocean surface, land and underwater, have also been increasingly relying upon real-time systems for monitoring and operational safety purposes, and for retaliatory and containment measures. In telecommunications and in multi-media applications, real time characteristics are essential to maintain the integrity of transmitted data, audio and video signals. Many of these systems control, monitor or perform critical operations, and must respond quickly to emergency events in a wide range of embedded applications. They are therefore required to process tasks with stringent timing requirements and must perform these tasks in a way that these timing requirements are guaranteed to be met. Real-time scheduling al gorithms attempt to ensure that system timing behavior meets its specifications, but typically assume that tasks do not share logical or physical resources. Since resource-sharing cannot be eliminated, synchronization primitives must be used to ensure that resource consis tency constraints are not violated.

Book Synopsis Soft Real-Time Systems: Predictability vs. Efficiency by : Giorgio C Buttazzo
Download or read book Soft Real-Time Systems: Predictability vs. Efficiency written by Giorgio C Buttazzo and published by Springer Science & Business Media. This book was released on 2006-07-02 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hard real-time systems are very predictable, but not sufficiently flexible to adapt to dynamic situations. They are built under pessimistic assumptions to cope with worst-case scenarios, so they often waste resources. Soft real-time systems are built to reduce resource consumption, tolerate overloads and adapt to system changes. They are also more suited to novel applications of real-time technology, such as multimedia systems, monitoring apparatuses, telecommunication networks, mobile robotics, virtual reality, and interactive computer games. This unique monograph provides concrete methods for building flexible, predictable soft real-time systems, in order to optimize resources and reduce costs. It is an invaluable reference for developers, as well as researchers and students in Computer Science.
Book Synopsis Fault-Tolerant Real-Time Systems by : Stefan Poledna
Download or read book Fault-Tolerant Real-Time Systems written by Stefan Poledna and published by Springer Science & Business Media. This book was released on 2007-11-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time computer systems are very often subject to dependability requirements because of their application areas. Fly-by-wire airplane control systems, control of power plants, industrial process control systems and others are required to continue their function despite faults. Fault-tolerance and real-time requirements thus constitute a kind of natural combination in process control applications. Systematic fault-tolerance is based on redundancy, which is used to mask failures of individual components. The problem of replica determinism is thereby to ensure that replicated components show consistent behavior in the absence of faults. It might seem trivial that, given an identical sequence of inputs, replicated computer systems will produce consistent outputs. Unfortunately, this is not the case. The problem of replica non-determinism and the presentation of its possible solutions is the subject of Fault-Tolerant Real-Time Systems: The Problem of Replica Determinism. The field of automotive electronics is an important application area of fault-tolerant real-time systems. Systems like anti-lock braking, engine control, active suspension or vehicle dynamics control have demanding real-time and fault-tolerance requirements. These requirements have to be met even in the presence of very limited resources since cost is extremely important. Because of its interesting properties Fault-Tolerant Real-Time Systems gives an introduction to the application area of automotive electronics. The requirements of automotive electronics are a topic of discussion in the remainder of this work and are used as a benchmark to evaluate solutions to the problem of replica determinism.

Book Synopsis Foundations of Real-Time Computing: Scheduling and Resource Management by : André M. van Tilborg
Download or read book Foundations of Real-Time Computing: Scheduling and Resource Management written by André M. van Tilborg and published by Springer Science & Business Media. This book was released on 1991-07-31 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of papers that focus on the state-of the-art in real-time scheduling and resource management. Preliminary versions of these papers were presented at a workshop on the foundations of real-time computing sponsored by the Office of Naval Research in October, 1990 in Washington, D.C. A companion volume by the title Foundations of Real-Time Computing: Fonnal Specifications and Methods complements this book by addressing many of the most advanced approaches currently being investigated in the arena of formal specification and verification of real-time systems. Together, these two texts provide a comprehensive snapshot of current insights into the process of designing and building real-time computing systems on a scientific basis. Many of the papers in this book take care to define the notion of real-time system precisely, because it is often easy to misunderstand what is meant by that term. Different communities of researchers variously use the term real-time to refer to either very fast computing, or immediate on-line data acquisition, or deadline-driven computing. This text is concerned with the very difficult problems of scheduling tasks and resource management in computer systems whose performance is inextricably fused with the achievement of deadlines. Such systems have been enabled for a rapidly increasing set of diverse end-uses by the unremitting advances in computing power per constant-dollar cost and per constant-unit-volume of space. End-use applications of deadline-driven real-time computers span a spectrum that includes transportation systems, robotics and manufacturing, aerospace and defense, industrial process control, and telecommunications.

Book Synopsis Bounding the End-to-end Response Times of Tasks in a Distributed Real-time System Using the Direct Synchronization Protocol by : Jun Sun
Download or read book Bounding the End-to-end Response Times of Tasks in a Distributed Real-time System Using the Direct Synchronization Protocol written by Jun Sun and published by . This book was released on 1996 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In a distributed real-time system, a task may consist of a chain of subtasks which execute on different processors. In order to guarantee that all timing constraints are met in such a system, it is imperative to be able to determine the end-to-end response time for each task. This report focuses on distributed systems where tasks are periodic and scheduled according to fixed priority scheduling algorithms. Moreover, if a subtask has predecessors, every instance of the subtask is released as soon as the corresponding instance of the immediate predecessor subtask completes. This report describes an algorithm that can be used to find upper bounds on the end-to-end response times of tasks in such a distributed real-time system."
