Worst Case Execution Time Aware Compilation Techniques For Real Time Systems

Download or read book Worst-Case Execution Time Aware Compilation Techniques for Real-Time Systems written by Paul Lokuciejewski and published by Springer Science & Business Media. This book was released on 2010-09-24 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: For real-time systems, the worst-case execution time (WCET) is the key objective to be considered. Traditionally, code for real-time systems is generated without taking this objective into account and the WCET is computed only after code generation. Worst-Case Execution Time Aware Compilation Techniques for Real-Time Systems presents the first comprehensive approach integrating WCET considerations into the code generation process. Based on the proposed reconciliation between a compiler and a timing analyzer, a wide range of novel optimization techniques is provided. Among others, the techniques cover source code and assembly level optimizations, exploit machine learning techniques and address the design of modern systems that have to meet multiple objectives. Using these optimizations, the WCET of real-time applications can be reduced by about 30% to 45% on the average. This opens opportunities for decreasing clock speeds, costs and energy consumption of embedded processors. The proposed techniques can be used for all types real-time systems, including automotive and avionics IT systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest research findings, as well as innovative theoretical and practical research results, methods and development techniques related to P2P, grid, cloud and Internet computing. It also reveals the synergies among such large scale computing paradigms. P2P, Grid, Cloud and Internet computing technologies have rapidly become established as breakthrough paradigms for solving complex problems by enabling aggregation and sharing of an increasing variety of distributed computational resources on a large scale. Grid computing originated as a paradigm for high-performance computing, offering an alternative to expensive supercomputers through different forms of large-scale distributed computing. P2P computing emerged as a new paradigm following on from client-server and web-based computing and has proved useful in the development of social networking, B2B (Business to Business), B2C (Business to Consumer), B2G (Business to Government), and B2E (Business to Employee). Cloud computing has been described as a “computing paradigm where the boundaries of computing are determined by economic rationale rather than technical limits”. Cloud computing has fast become the computing paradigm with applicability and adoption in all domains and providing utility computing at large scale. Lastly, Internet computing is the basis of any large-scale distributed computing paradigm; it has very quickly developed into a vast and flourishing field with enormous impact on today’s information societies and serving as a universal platform comprising a large variety of computing forms such as grid, P2P, cloud and mobile computing.

Download or read book Embedded Software written by Jérôme Dern and published by BoD - Books on Demand. This book was released on 2015-07-21 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the various types of software, Embedded Software is a class of its own: it ensures critical missions and if wrongly designed it can disturb the human organization, lead to large losses, injure or kill many people. Updates are difficult and rather expensive or even impossible. Designing Embedded Software needs to include quality in the development process, but economic competition requires designing less expensive products. This book addresses Embedded Software developers, Software Quality Engineers, Team Leaders, Project Managers, and R&D Managers. The book we will introduce Embedded Software, languages, tools and hardware. Then, we will discuss the challenges of Software Quality. Software Development life cycles will be presented with their advantages and disadvantages. Main standards and norms related to software and safety will be discussed. Next, we will detail the major development processes and propose a set of processes compliant with CMMI-DEV, SPICE, and SPICE- HIS. Agile methods as well as DO-178C and ISO 26262 will have specific focus when necessary. To finish, we will promote quality tools needed for capitalization and reaching software excellence.

Download or read book High-Performance and Time-Predictable Embedded Computing written by Pinho, Luis Miguel and published by River Publishers. This book was released on 2018-07-04 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, the prevalence of computing systems in our lives is so ubiquitous that we live in a cyber-physical world dominated by computer systems, from pacemakers to cars and airplanes. These systems demand for more computational performance to process large amounts of data from multiple data sources with guaranteed processing times. Actuating outside of the required timing bounds may cause the failure of the system, being vital for systems like planes, cars, business monitoring, e-trading, etc. High-Performance and Time-Predictable Embedded Computing presents recent advances in software architecture and tools to support such complex systems, enabling the design of embedded computing devices which are able to deliver high-performance whilst guaranteeing the application required timing bounds. Technical topics discussed in the book include: Parallel embedded platformsProgramming modelsMapping and scheduling of parallel computationsTiming and schedulability analysisRuntimes and operating systems The work reflected in this book was done in the scope of the European project P‑SOCRATES, funded under the FP7 framework program of the European Commission. High-performance and time-predictable embedded computing is ideal for personnel in computer/communication/embedded industries as well as academic staff and master/research students in computer science, embedded systems, cyber-physical systems and internet-of-things.

Download or read book Time-Predictable Architectures written by Christine Rochange and published by John Wiley & Sons. This book was released on 2014-01-17 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building computers that can be used to design embedded real-time systems is the subject of this title. Real-time embedded software requires increasingly higher performances. The authors therefore consider processors that implement advanced mechanisms such as pipelining, out-of-order execution, branch prediction, cache memories, multi-threading, multicorearchitectures, etc. The authors of this book investigate the timepredictability of such schemes.
