Download or read book Real time Systems Scheduling 1 written by Maryline Chetto and published by John Wiley & Sons. This book was released on 2014-11-17 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time systems are used in a wide range of applications, including control, sensing, multimedia, etc. Scheduling is a central problem for these computing/communication systems since responsible of software execution in a timely manner. This book provides state of knowledge in this domain with special emphasis on the key results obtained within the last decade. This book addresses foundations as well as the latest advances and findings in Real-Time Scheduling, giving all references to important papers. But nevertheless the chapters will be short and not overloaded with confusing details. Coverage includes scheduling approaches for mono-core as well as multi-core platforms, dependent tasks, networks, and notably very tremendous recent advances in scheduling of energy constrained embedded systems. Other sophisticated issues such as feedback control scheduling and timing analysis of critical applications are also addressed. This volume can serve as a textbook for courses on the topic in bachelor and in more advanced master programs. It also provides a reference for computer scientists and engineers involved in the design or the development of Cyber-Physical Systems which require up-to-date real-time scheduling solutions.
Download or read book Deadline Scheduling for Real Time Systems written by John A. Stankovic and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many real-time systems rely on static scheduling algorithms. This includes cyclic scheduling, rate monotonic scheduling and fixed schedules created by off-line scheduling techniques such as dynamic programming, heuristic search, and simulated annealing. However, for many real-time systems, static scheduling algorithms are quite restrictive and inflexible. For example, highly automated agile manufacturing, command, control and communications, and distributed real-time multimedia applications all operate over long lifetimes and in highly non-deterministic environments. Dynamic real-time scheduling algorithms are more appropriate for these systems and are used in such systems. Many of these algorithms are based on earliest deadline first (EDF) policies. There exists a wealth of literature on EDF-based scheduling with many extensions to deal with sophisticated issues such as precedence constraints, resource requirements, system overload, multi-processors, and distributed systems. Deadline Scheduling for Real-Time Systems: EDF and Related Algorithms aims at collecting a significant body of knowledge on EDF scheduling for real-time systems, but it does not try to be all-inclusive (the literature is too extensive). The book primarily presents the algorithms and associated analysis, but guidelines, rules, and implementation considerations are also discussed, especially for the more complicated situations where mathematical analysis is difficult. In general, it is very difficult to codify and taxonomize scheduling knowledge because there are many performance metrics, task characteristics, and system configurations. Also, adding to the complexity is the fact that a variety of algorithms have been designed for different combinations of these considerations. In spite of the recent advances there are still gaps in the solution space and there is a need to integrate the available solutions. For example, a list of issues to consider includes: preemptive versus non-preemptive tasks, uni-processors versus multi-processors, using EDF at dispatch time versus EDF-based planning, precedence constraints among tasks, resource constraints, periodic versus aperiodic versus sporadic tasks, scheduling during overload, fault tolerance requirements, and providing guarantees and levels of guarantees (meeting quality of service requirements). Deadline Scheduling for Real-Time Systems: EDF and Related Algorithms should be of interest to researchers, real-time system designers, and instructors and students, either as a focussed course on deadline-based scheduling for real-time systems, or, more likely, as part of a more general course on real-time computing. The book serves as an invaluable reference in this fast-moving field.

Download or read book Integrating Best effort Policies Into Hard Real time Systems Based on Fixed Priority Pre emptive Scheduling written by R. I. Davis and published by . This book was released on 1994 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Analysis is provided for fixed priority pre-emptive scheduling enables a priori guarantees to be given regarding the timing requirements of critical tasks. By comparison, Best-Effort scheduling maximises system utility, but at best provides only probabilistic guarantees that time constraints will be met. In this paper, we show how these two schemes can be integrated. A new Adaptive Value-Density Threshold policy is introduced which approximates the Best-Effort policy but incurs much lower overheads. This policy is used to admit optional (utility enhancing) tasks for on-line acceptance testing. If guaranteed such components are assigned a fixed priority and executed when no higher priority tasks are runnable. This approach combines the benefits of guaranteeing hard requirements with increased system utility, resilience to software failures and increased application robustness."

Download or read book Schedulability Criteria for Fixed Priority Scheduling of Real Time Systems written by Dong-Won Park and published by . This book was released on 1992 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "There are two major approaches to guaranteeing hard real-time deadlines for periodic tasks using scheduling algorithms based on fixed priorities: utilization bound checks, which check the total expected processor utilization, and do not require detailed information about the taskset; and exact schedulability checks, which use detailed information. In this work, we present a technique for determining period-specific utilization bounds, which use task period information, generally available at design time, but not task computation time information, which is hard to determine accurately. The technique we use for determining the bound is an innovative approach which makes use of linear programming."

Being APCHDL bi-annual, this book presents a selection of papers from HDLCon'Ol and FDL'OI. HDLCon is the premier HDL event in the United States. It originated in 1999 from the merging of the International Verilog Conference and the Spring VHDL User's Forum. The scope of the conference expanded from specialized languages such as VHDL and Verilog to general purpose languages such as C++ and Java. In 2001 it was held in February in Santa Clara, CA. Presentations from design engineers are technical in nature, reflecting real life experiences in using HDLs. EDA vendors presentations show what is available - and what is planned-for design tools that utilize HDLs, such as simulation and synthesis tools. The Forum on Design Languages (FDL) is the European forum to exchange experiences and learn of new trends, in the application of languages and the associated design methods and tools, to design complex electronic systems. FDL'OI was held in Lyon, France, around seven interrelated workshops, Hardware Description Languages, Analog and Mixed signal Specification, C/C++ HW/SW Specification and Design, Design Environments & Languages, Real-Time specification for embedded Systems, Architecture Modeling and Reuse and System Specification & Design Languages.
