This book was released on 2013 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time embedded systems need to be analyzed at an early stage in order to detect temporal vulnerabilities. Indeed, software development costs are sharply impacted by wrong design choices made in the early stages of development, in particular during the design phase, but often detected after the implementation. The schedulability analysis is one of the main analyses required to ensure the timing correctness of a real-time system. Indeed, the real-time scheduling theory has been devoted to propose different models providing several levels of expressiveness, and different analytical methods with different levels of accuracy. The utilization of the real-time scheduling theory in practical cases could be profitable. Unfortunately, it is not sufficiently applied and research results have been exploited in an industrial context only to amodest extent to date. Actually, a difficulty faced by the real-time designers is to find the appropriate analysis test shelping to validate properly the system and also to reduce the over-dimensioning. This thesis is interested in the chasmexisting between real-time design community and real-time analysis community. The purpose of our work is to fill the gap between the modeling of real-time systems and the scheduling analysis. Then, we propose a decision aiding solution based on model-driven engineering. Our solution is dedicated (i) to increase the usage of the real-time scheduling theory,(ii) to facilitate the scheduling analysis tests choice and (iii) to reduce the pessimism during the design phase of real-time systems. Our proposal is embodied as a framework unifying the designers and analysts efforts. The framework called MoSaRT offers a design language very close to the taxonomy of real-time scheduling theory. Moreover, MoSaRT provides ananalysis repository concept to enhance the applicability of the scheduling theory and also to improve the way designers check their designs.

Available in PDF, EPUB and Kindle. Book excerpt: The Computer Aided Prototyping System (CAPS) and the Prototype system Description Language (PSDL) represent a pioneering effort in the field of software development. Execution Support System (ESS) within the framework of CAPS. The Static Scheduler is one of the critical elements of the ESS which extracts critical timing constraints and precedence constraints for operators and schedules the time-critical operators to guarantee that their timing constraints will be met. The Static Scheduler uses the information of timing constraints and precedence constraints to determine whether a feasible schedule can be built. This construction provides the foundation for handling the execution for Real-Time systems. The goal of this thesis is to provide improved versions of the Static Scheduler. (Author) (kr).

Download or read book Distributed Hard Real time Scheduling for a Software Prototyping Environment written by Mauricio de Menezes Cordeiro and published by . This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scheduling analysis is one of the most important activities in hard real-time systems development since the correctness of hard real-time systems depends not only on the logical results of computation, but also on the time at which the results are produced. This dissertation aimed at the development of both fundamental theory and software tools to support efficiently and reliably the scheduling of distributed hard real-time systems. The major work of this dissertation focuses on non-preemptive hard real-time scheduling, for periodic and sporadic task sets, although some of the results are also applicable to the Preemptive case. Several theorems for checking the schedulability of non-preemptive task sets are developed. Previous results on necessary and sufficient conditions for scheduling non-preemptive task sets are extended to cover the case when the task deadlines can be smaller or equal to their periods. The concept of transient and cyclic schedules is introduced to overcome the weakness of the traditional methods, which restrict the construction of a cyclic schedule to a fixed interval of length equal to the least common multiple of the periods.
Download or read book Co design Approaches to Dependable Networked Control Systems written by Daniel Simon and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networked Control Systems (NCS) is a growing field of application and calls for the development of integrated approaches requiring multidisciplinary skills in control, real-time computing and communication protocols. This book describes co-design approaches, and establishes the links between the QoC (Quality of Control) and QoS (Quality of Service) of the network and computing resources. The methods and tools described in this book take into account, at design level, various parameters and properties that must be satisfied by systems controlled through a network. Among the important network properties examined are the QoC, the dependability of the system, and the feasibility of the real-time scheduling of tasks and messages. Correct exploitation of these approaches allows for efficient design, diagnosis, and implementation of the NCS. This book will be of great interest to researchers and advanced students in automatic control, real-time computing, and networking domains, and to engineers tasked with development of NCS, as well as those working in related network design and engineering fields.

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.
Download or read book Introduction to Embedded Systems Second Edition written by Edward Ashford Lee and published by MIT Press. This book was released on 2017-01-06 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the engineering principles of embedded systems, with a focus on modeling, design, and analysis of cyber-physical systems. The most visible use of computers and software is processing information for human consumption. The vast majority of computers in use, however, are much less visible. They run the engine, brakes, seatbelts, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They command robots on a factory floor, power generation in a power plant, processes in a chemical plant, and traffic lights in a city. These less visible computers are called embedded systems, and the software they run is called embedded software. The principal challenges in designing and analyzing embedded systems stem from their interaction with physical processes. This book takes a cyber-physical approach to embedded systems, introducing the engineering concepts underlying embedded systems as a technology and as a subject of study. The focus is on modeling, design, and analysis of cyber-physical systems, which integrate computation, networking, and physical processes. The second edition offers two new chapters, several new exercises, and other improvements. The book can be used as a textbook at the advanced undergraduate or introductory graduate level and as a professional reference for practicing engineers and computer scientists. Readers should have some familiarity with machine structures, computer programming, basic discrete mathematics and algorithms, and signals and systems.
