This is something of a curious, atypical book for the technical genre (and as the author, I should know). I say this because this tome is intended to be of interest to an unusually broad and diverse readership. The primary audience comprises fully fledged engineers who are currently designing with field programmable gate arrays (FPGAs) or who are planning to do so in the not-so-distant future. Thus, Section 2: Creating FPGABased Designs introduces a wide range of different design flows, tools, and concepts with lots of juicy technical details that only an engineer could love. By comparison, other areas of the book—such as Section 1: Fundamental Concepts—cover a variety of topics at a relatively low technical level. The reason for this dichotomy is that there is currently a tremendous amount of interest in FPGAs, especially from people who have never used or considered them before. The first FPGA devices were relatively limited in the number of equivalent logic gates they supported and the performance they offered, so any “serious” (large, complex, high-performance) designs were automatically implemented as application-specific integrated circuits (ASICs) or application-specific standard parts (ASSPs). However, designing and building ASICs and ASSPs is an extremely time-consuming and expensive hobby, with the added disadvantage that the final design is “frozen in silicon” and cannot be easily modified without creating a new version of the device. By comparison, the cost of creating an FPGA design is much lower than that for an ASIC or ASSP. At the same time, implementing design changes is much easier in FPGAs and the time-to-market for such designs is much faster. Of particular interest is the fact that new FPGA architectures Preface

How This Book Is Organized While waiting for chapters to trickle in, we were afraid we would end up with different versions of “this is how you test” or “keep the bar green.” Much to our relief, we ended up with a diverse mixture. Manifestos, detailed case studies, touching experience reports, and war stories from the trenches—Beautiful Testing has a bit of each. The chapters themselves almost seemed to organize themselves naturally into sections. Part I, Beautiful Testers Testing is an inherently human activity; someone needs to think of the test cases to be automated, and even those tests can’t think, feel, or get frustrated. Beautiful Testing therefore starts with the human aspects of testing, whether it is the testers themselves or the interactions of testers with the wider world. Chapter 1, Was It Good for You? Linda Wilkinson brings her unique perspective on the tester’s psyche. Chapter 2, Beautiful Testing Satisfies Stakeholders Rex Black has been satisfying stakeholders for 25 years. He explains how that is beautiful. Chapter 3, Building Open Source QA Communities Open source projects live and die by their supporting communities. Clint Talbert and Martin Schröder share their experiences building a beautiful community of testers.

Presenting the fundamental principles of cooperative communications and networking, this book treats the concepts of space, time, frequency diversity, and MIMO, with a holistic approach to principal topics where significant improvements can be obtained. Beginning with background and MIMO systems, Part I includes a review of basic principles of wireless communications, space–time diversity and coding, and broadband space–time–frequency diversity and coding. Part II then goes on to present topics on physical layer cooperative communications, such as relay channels and protocols, performance bounds, optimum power control, multi-node cooperation, distributed space–time and space–frequency coding, relay selection, differential cooperative transmission, and energy efficiency. Finally, Part III focuses on cooperative networking including cooperative and content–aware multiple access, distributed routing, source– channel coding, source–channel diversity, coverage expansion, broadband cooperative communications, and network lifetime maximization. With end-of-chapter review questions included, this text will appeal to graduate students of electrical engineering and is an ideal textbook for advanced courses on wireless communications. It will also be of great interest to practitioners in the wireless communications industry.

With the great advances in digital data compression (coding) technologies and the rapid growth in the use of IP-based Internet, along with the quick deployment of last-mile wireline and wireless broadband access, networked multimedia applications have created a tremendous impact on computing and network infrastructures. The four most critical and indispensable components involved in a multimedia networking system are: (1) data compression (source encoding) of multimedia data sources, e.g., speech, audio, image, and video; (2) quality of service (QoS) streaming architecture design issues for multimedia delivery over best-effort IP networks; (3) effective dissemination multimedia over heterogeneous IP wireless broadband networks, where the QoS is further degraded owing to the dynamic changes in end-to-end available bandwidth caused by wireless fading or shadowing and link adaptation; (4) effective digital rights management and adaptation schemes, which are needed to ensure proper intellectual property management and protection of networked multimedia content. This book has been written to provide an in-depth understanding of these four major considerations and their critical roles in multimedia networking. More specifically, it is the first book to provide a complete system design perspective based on existing international standards and state-of-the-art networking and infrastructure technologies, from theoretical analyses to practical design considerations. The book also provides readers with learning experiences in multimedia networking by offering many development-software samples for multimedia data capturing, compression, and streaming for PC devices, as well as GUI designs for multimedia applications. The coverage of the material in this book makes it appropriate as a textbook for a one-semester or two-quarter graduate course. Moreover, owing to its balance of theoretical knowledge building and practical design integration, it can serve also as a reference guide for researchers working in this subject or as a handbook for practising engineers.

Linux is a relatively new operating system that has begun to enjoy a lot of attention from the business and academic worlds. As the operating system matures, its feature set, capabilities and performance grow but so does its size and complexity. The table in Figure 1.1 shows the size of the kernel source code and size in bytes

I've been working with Windows CE for almost as long as it's been in existence. A Windows programmer for many years, I'm amazed by the number of different, typically quite small, systems to which I can apply my Windows programming experience. These Windows CE systems run the gamut from PC-like mini-laptops to embedded devices buried deep in some large piece of industrial equipment. The use of the Win32 API in Windows CE enables tens of thousands of Windows programmers to write applications for an entirely new class of systems. The subtle differences, however, make writing Windows CE code somewhat different from writing for the desktop versions of Windows. It's those differences that I'll address in this book
