This paper presents power management guidelines for PCI Express links on Intel-based Mobile platforms. It describes the mapping from platform sleeping states and device power states to link power states, including the procedure to support Mobile-specific S1/POS and CPU C3/C4 scenarios. Device and platform power saving opportunities are identified for each link power state. L1 entry policy is also recommended to optimize device power. Several power optimization techniques are described, including minimizing flow control updates and acknowledgement packets to improve bandwidth efficiency, and pipelining packets to increase opportunities for active state link power management. These power management guidelines enable architectural innovation to achieve power-optimized interconnect performance.

Device drivers literally drive everything you're interested in--disks, monitors, keyboards, modems--everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge. For years now, programmers have relied on the classic Linux Device Drivers from O'Reilly to master this critical subject. Now in its third edition, this bestselling guide provides all the information you'll need to write drivers for a wide range of devices. Over the years the book has helped countless programmers learn: * how to support computer peripherals under the Linux operating system * how to develop and write software for new hardware under Linux * the basics of Linux operation even if they are not expecting to write a driver The new edition of Linux Device Drivers is better than ever. The book covers all the significant changes to Version 2.6 of the Linux kernel, which simplifies many activities, and contains subtle new features that can make a driver both more efficient and more flexible. Readers will find new chapters on important types of drivers not covered previously, such as consoles, USB drivers, and more. Best of all, you don't have to be a kernel hacker to understand and enjoy this book. All you need is an understanding of the C programming language and some background in Unix system calls. And for maximum ease-of-use, the book uses full-featured examples that you can compile and run without special hardware. Today Linux holds fast as the most rapidly growing segment of the computer market and continues to win over enthusiastic adherents in many application areas. With this increasing support, Linux is now absolutely mainstream, and viewed as a solid platform for embedded systems. If you're writing device drivers, you'll want this book. In fact, you'll wonder how drivers are ever written without it.

This book is a beginner’s guide, but it assumes a familiarity with programming basics. And it concentrates on explaining the aspects of C++/CLI that make it the most powerful and fun language of the .NET Framework. As such, this book is ideal if you’re thinking of migrating to C++/CLI from another language. By the end of this book, you’ll have a thorough grounding in the core language elements together with the confidence to explore further that comes from a solid understanding of a language’s syntax and grammar.

Book Description Learn how to harness the power of delta-sigma data converters Understanding Delta-Sigma Data Converters brings readers a clear understanding of the principles of delta-sigma (ΔΣ) converter operation—analog to digital and digital to analog. It introduces the best computer-aided analysis and design techniques available. With an understanding of the great versatility of the ΔΣ converter, readers can apply their new knowledge to a wide variety of applications, including digital telephony, digital audio, wireless and wired communications, medical electronics, and industrial and scientific instrumentation. The authors make the material accessible to all design engineers by focusing on developing an understanding of the physical operation rather than getting mired in complex mathematical treatments and derivations. Written for entry-level readers, the publication has a natural flow that begins with basic concepts, enabling the readers to develop a solid foundation for the book's more complex material. The text, therefore, starts with a general introduction to the ΔΣ converter, including a brief historical overview to place it in context. Next, the publication introduces the first-order ΔΣ modulator, covering oversampling, noise-shaping, decimation filtering and other key concepts. Then, using the first-order modulator as a foundation, second and higher-order modulators are presented and analyzed. Finally, the authors delve into implementation considerations and present several design examples using the Delta-Sigma Toolbox. Everything needed to facilitate quick comprehension and help readers apply their newly learned principles is provided: Simplified methods to understand complicated concepts such as spectral estimation and switched noise References that lead to in-depth analysis of specialized topics Figures and charts that illustrate complex design issues Conclusion section at the end of each chapter that highlights the key points Reference manual for the Delta-Sigma Toolbox, along with numerous practical examples that illustrate the use of the Toolbox This is essential reading for all design engineers who want to learn and fully harness the powerful capabilities of ΔΣ data converters. Upper-level undergraduates and graduate students will find the book's logical organization and clear style, coupled with numerous practical examples, a great entry into the field.

C++/CLI is Microsoft's latest extension to C++ that targets the heart of .NET 2.0, the common language runtime. Expert Visual C++/CLI is written by visual C++ MVP Marcus Heege, who examines the core of the C++/CLI language. He explains both how the language elements work and how Microsoft intends them to be used. Even if you're new to C++/CLI but are planning to migrate to it from another language, this book will ground you in the core language elements and give you the confidence to explore further and migrate effectively. It provides concise, yet in-depth coverage of all major C++/CLI features: short code examples succinctly illustrate syntax and concepts, and more elaborate examples show how C++/CLI should be used
