From the Foreword: "...the presentation of real-time scheduling is probably the best in terms of clarity I have ever read in the professional literature. Easy to understand, which is important for busy professionals keen to acquire (or refresh) new knowledge without being bogged down in a convoluted narrative and an excessive detail overload. The authors managed to largely avoid theoretical-only presentation of the subject, which frequently affects books on operating systems. ... an indispensable [resource] to gain a thorough understanding of the real-time systems from the operating systems perspective, and to stay up to date with the recent trends and actual developments of the open-source real-time operating systems." —Richard Zurawski, ISA Group, San Francisco, California, USA Real-time embedded systems are integral to the global technological and social space, but references still rarely offer professionals the sufficient mix of theory and practical examples required to meet intensive economic, safety, and other demands on system development. Similarly, instructors have lacked a resource to help students fully understand the field. The information was out there, though often at the abstract level, fragmented and scattered throughout literature from different engineering disciplines and computing sciences. Accounting for readers’ varying practical needs and experience levels, Real Time Embedded Systems: Open-Source Operating Systems Perspective offers a holistic overview from the operating-systems perspective. It provides a long-awaited reference on real-time operating systems and their almost boundless application potential in the embedded system domain. Balancing the already abundant coverage of operating systems with the largely ignored real-time aspects, or "physicality," the authors analyze several realistic case studies to introduce vital theoretical material. They also discuss popular open-source operating systems—Linux and FreRTOS, in particular—to help embedded-system designers identify the benefits and weaknesses in deciding whether or not to adopt more traditional, less powerful, techniques for a project.

The emergence of new soft real-time applications such as DVRs (Digital Video Recorders) and other multimedia devices has caused an explosion in the number of embedded real-time systems in use and development. Many engineers working on these emergent products could use a practical and in depth primer on how to apply real-time theory to get products to market quicker, with fewer problems, and better performance. Real-Time Embedded Systems and Components introduces practicing engineers and advanced students of engineering to real-time theory, function, and tools applied to embedded applications. The first portion of the book provides in-depth background on the origins of real-time theory including rate monotonic and dynamic scheduling. From there it explores the use of rate monotonic theory for hard real-time applications commonly used in aircraft flight systems, satellites, telecommunications, and medical systems. Engineers also learn about dynamic scheduling for use in soft real-time applications such as video on demand, VoIP (Voice over Internet Protocol), and video gaming. Sample code is presented and analyzed based upon Linux and VxWorks operating systems running on a standard Intel architecture PC. Finally, readers will be able to build working robotics, video, machine vision, or VoIP projects using low-cost resources and approaches to gain hands on real-time application experience. Real-Time Embedded Systems and Components is the one single text that provides an in-depth introduction to the theory along with real world examples of how to apply it.

Specification and design methodology has seen significant growth as a research area over the last decade, tracking but lagging behind VLSI design technology in general and the CAD industry in particular. The commercial rush to market tries to leverage existing technology which fuels CAD design tool development. Paralleling this is very active basic and applied research to investigate and move forward rational and effective methodologies for accomplishing digital design, especially in the field of hardware/software codesign. It is this close relationship between industry and academia that makes close cooperation between researchers and practitioners so important-and monographs like this that combine both abstract concept and pragmatic implementation deftly bridge this often gaping chasm. It was at the IEEE/ACM Eighth International Symposium on Hardware/Software Codesign where I met the author of this monograph, Dr. Randall Janka, who was presenting some of his recent dissertation research results on specification and design methodology, or as he has so succinctly defined this sometimes ambiguous concept, "the tools and rules." Where so many codesign researchers are trying to prove out different aspects of codesign and using toy applications to do so, Dr. Janka had developed a complete specification and design methodology and prototyped the infrastructure-and proven its viability, utility, and effectiveness using a demanding real-world application of a real-time synthetic aperture radar imaging processor that was implemented with embedded parallel processors.
