The arrival and popularity of multi-core processors has sparked a renewed interest in the development of parallel programs. Similarly, the availability of low-cost microprocessors and sensors has generated a great interest in embedded real-time programs. This book provides students and programmers whose backgrounds are in traditional sequential programming with the opportunity to expand their capabilities into parallel, embedded, real-time and distributed computing. It also addresses the theoretical foundation of real-time scheduling analysis, focusing on theory that is useful for actual applications. Written by award-winning educators at a level suitable for undergraduates and beginning graduate students, this book is the first truly entry-level textbook in the subject. Complete examples allow readers to understand the context in which a new concept is used, and enable them to build and run the examples, make changes, and observe the results.

Ada is the only ISO-standard, concurrent, real-time programming language. It is intended for use in big, long-lived applications where reliability & efficiency are essential, particularly real-time & embedded systems. In this book, the authors give a thorough account of how the Ada tasking model can be used to build a wide range of systems.

Ada is the programming language of choice for high integrity software systems and is used extensively in industries such as transportation and aerospace. Special features of the book include: Object-oriented programming, concurrency, and embedded and real-time systems are emphasized. Ada for Software Engineers explains the language concepts and the terminology of the standards document, the Ada Reference Manual (ARM). Extracts from the ARM are used throughtout and there are extensive cross references to the ARM. A comprehensive glossary and technical quizzes assist the reader in developing the ability to use the ARM as a practical reference. Comparisons with familiar languages like C and Java are given to facilitate the transition to Ada. The features of Ada 2005 are used routinely, but they are carefully identified, so that programmers using Ada 95 will also find the textbook useful. The companion website contains the full source code of nearly 100 case studies and 100 technical quizzes.

The concept of concurrency presents a real difficulty to many programmers. In this book Dr Burns introduces the topic and shows how the Ada programming language, which had as a main design specification that it should contain the features necessary for concurrent programming, deals with it. The need to produce software that models inherent parallelism is important in many applications, including embedded real time systems, process control and general purpose multi-processor system software. Although for many other applications of Ada, knowledge of the Tasking Model is not necessary the full power of the language can only really be obtained if this model is understood.

A major feature of the Ada programming language is the facilities it provides for concurrent programming. Alan Burns and Andy Wellings provide here a thorough and self-contained account of concurrent programming in Ada, and so show users, even beginners, how to harness the full power of the whole language. After giving an overview of the non-concurrent features of Ada, the authors proceed to examine in detail the uses of concurrent programming and the inherent difficulties in providing inter-process communication. The Ada tasking model is then introduced; the way it deals with these and related matters is explained in a number of separate chapters, covering system programming, real-time issues, distribution, object-oriented programming and re-use. This is the first book which deals with concurrent features in the new Ada standard, and it offers practical advice to the programmer needing to use it for embedded systems, while those interested more broadly in the development of programming languages will find many otherwise inaccessible issues probed in depth. It will thus be of value to professional software engineers and advanced students of programming alike; indeed, every Ada programmer will find it essential reading and a primary reference work. For the paperback edition the authors have made revisions throughout the text, updating and correcting where appropriate.

The Ada programming language was created by the U.S. Department of Defense (DOD) nearly two decades ago to provide a general-purpose programming language for defense and commercial use, but has evolved into a niche solution for safety-critical systems, primarily in defense applications. Ada and Beyond presents an approach for the DOD to move beyond the debate over its policy that requires the use of Ada for all new software development. It describes the importance of the software engineering process and recommends to DOD mechanisms for more effective review of software development and improved collection of data on software project outcomes. The volume also analyzes the technical, empirical, and business cases for using Ada and other programming languages, makes recommendations regarding the appropriate conditions under which DOD should continue to require the use of Ada, and details activities that require funding by DOD in order for Ada to remain a viable programming language.

This book constitutes the proceedings of the 14th Ada-Europe International Conference on Reliable Software Technologies, Ada-Europe 2009, held in Brest, France, on June 8-12, 2009. The 19 papers presented were carefully reviewed and selected from numerous submissions. Topics of interest to the conference are methods and techniques for software development and maintenance; software architecture; enabling technology; software quality; theory and practice of high-integrity systems; embedded systems; mainstream and emerging applications; ada language and technology; ada and education.
