How do real-time systems differ from normal information processing systems? How can real-time systems be analysed to ensure they satisfy their temporal constraints? Which features are needed in programming languages to implement real-time systems? This latest book from Burns and Wellings answers these and other key questions about real-time systems. It provides an in-depth analysis of the requirements for designing and implementing real-time, embedded, cyber-physical systems, and discusses how these requirements are supported by the Ada programming language. No other book on real-time (or concurrent) programming covers the same breadth of material. Topics covered in this book include: The definition of real-time, its necessary characteristics and desirable properties. Scheduling schemes, including fixed priority scheduling, Earliest Deadline First and Value-based scheduling. Analysis methods, including response-time analysis and processor demand analysis. Introduction to the Ada programming language. Programming adaptive and predictable real-time systems in Ada. Programming reliable and fault-tolerant systems in Ada. Analysing and programming for multiprocessor and multicore platforms. Mixed-criticality systems The book is aimed at Final Year and Masters students in Computer Science and related disciplines. It has also been written with the professional software engineer, and real-time systems engineer, in mind. The material presented reflects the content of courses developed over a number of years by the authors at the University of York.

Started on the inspired initiative of Prof. Alfred Strohmeier back in 1996, and spawned from the annual Ada-Europe conference that had previously run for 16 consecutive years, the International Conference on Reliable Software Technologies celebrated this year its tenth anniversary by going to York, UK, where the ?rst series of technical meetings on Ada were held in the 1970s. Besides being a beautiful and historical place in itself, York also hosts the Depa- ment of Computer Science of the local university, whose Real-Time Group has been tremendously in?uential in shaping the Ada language and in the progress on real-time computing worldwide. This year's conference was therefore put together under exc- lent auspices, in a very important year for the Ada community in view of the forthc- ing completion of the revision process that is upgrading the language standard to face the challenges of the new millennium. The conference took place on June 20-24, 2005. It was as usual sponsored by Ada-Europe, the European federation of national Ada societies, in cooperation with ACM SIGAda. The conference was organized by selected staff of the University of York teamed up with collaborators from various places in Europe, in what turned out to be a very effective instance of distributed collaborative processing. The conference also enjoyed the generous support of 11 industrial sponsors.
