The aim of Surviving the SOC Revolution: A Guide to Platform-Based Design is to provide the engineering community with a thorough understanding of the challenges involved when moving to system-on-a-chip and deliver a step-by-step methodology to get them there. Design reuse is most effective in reducing the cost and development time when the components to be shared are close to the final implementation. On the other hand, it is not always possible or desirable to share designs at this level, since minimal variations in specification can result in different, albeit similar, implementations. However, moving higher in abstraction can eliminate the differences among designs, so that the higher level of abstraction can be shared and only a minimal amount of work needs to be carried out to achieve final implementation. The ultimate goal is to create a library of functions and of hardware and software implementations that can be used for all new designs. It is important to have a multilevel library, since it is often the case that the lower levels that are closer to the physical implementation change because of the advances in technology, while the higher levels tend to be stable across product versions. It is most likely that the preferred approaches to the implementation of complex embedded systems will include the following aspects: Design costs and time are likely to dominate the decision-making process for systems designers. Therefore, design reuse in all its shapes and forms will be of paramount importance. Designs have to be captured at the highest level of abstraction to be able to exploit all the degrees of freedom that are available. Next-generation systems will use a few highly complex (Moore's Law Limited) part-types, but many more energy-power-cost-efficient, medium-complexity (10M-100M) gates in 50nm technology chips, working concurrently to implement solutions to complex sensing, computing, and signaling/actuating problems. Such chips will most likely be developed as an instance of a particular platform. That is, rather than being assembled from a collection of independently developed blocks of silicon functionality, they will be derived from a specific `family' of rnicro-architectures, possibly oriented toward a particular class of problems, that can be modified (extended or reduced) by the system developer. These platforms will be highly programmable. Both system and software reuse impose a design methodology that has to leverage existing implementations available at all levels of abstraction. £/LIST£ This book deals with the basic principles of a design methodology that addresses the concerns expressed above. The platform concept is carried throughout the book as a unifying theme to reuse. This is the first book that deals with the platform-based approach to the design of embedded systems and is a stepping stone for anyone who is interested in the real issues facing the design of complex systems-on-chip.

Detective Jack Yu returns in a pulse-pounding fifth investigation in New York's Chinatown Chinatown gang leader "Lucky" Louie was shot outside of a Chinatown off-track betting establishment on the thirteenth of January, and lay in a coma for 88 days, waking on Easter Sunday. The number 88 is a double-helix, double-lucky Chinese number; religion and superstition all lean Lucky's way. But Detective Jack Yu, Lucky's boyhood blood brother, fears his friend's luck is about to run out. When Lucky embarks on a complex and daring series of crimes against the Chinatown criminal underground, Jack races to stop him before his enemies do so--permanently.

Detective Jack Yu grew up in Chinatown. Some of his friends are criminals now; some are dead. Jack has just been transferred to his old neighborhood, where 99 percent of the cops are white. Unlike the others, confused by the residents who speak another language even when they re speaking English, Jack knows what s going on. He is confronted with a serial rapist who preys on young Chinese girls. Then Uncle Four, an elderly and respected leader of the charitable Hip Ching Society and member of the Hong Kong-based Red Circle Triad, is gunned down. Jack learns that benevolent Uncle Four had a gorgeous young mistress imported from Hong Kong. And she is missing. To solve these crimes, Jack turns to an elderly fortune teller, an old friend of his, in addition to employing modern police methods. This debut mystery power-fully conveys the sights, sounds, and smells of Chinatown, as well as the attitudes of its inhabitants."

In "Death Money" novelist Henry Chang returns us to the Chinatown of NYPD Detective Jack Yu, and spins one of his most noir tales yet. When the body of an unidentified Asian man is found in the Harlem River, NYPD Detective Jack Yu is pulled in to investigate. The murder takes Jack from the benevolent associations of Chinatown to the take-out restaurants, strip clubs, and underground gambling establishments of the Bronx, to a wealthy, exclusive New Jersey borough. It's a world of secrets and unclear allegiances, of Chinatown street gangs and major Triad players. With the help of an elderly fortune teller and an old friend, the unpredictable Billy Bow, Jack races to solve his most difficult case yet. "From the Hardcover edition."

Analog circuit design is often the bottleneck when designing mixed analog-digital systems. A Top-Down, Constraint-Driven Design Methodology for Analog Integrated Circuits presents a new methodology based on a top-down, constraint-driven design paradigm that provides a solution to this problem. This methodology has two principal advantages: (1) it provides a high probability for the first silicon which meets all specifications, and (2) it shortens the design cycle. A Top-Down, Constraint-Driven Design Methodology for Analog Integrated Circuits is part of an ongoing research effort at the University of California at Berkeley in the Electrical Engineering and Computer Sciences Department. Many faculty and students, past and present, are working on this design methodology and its supporting tools. The principal goals are: (1) developing the design methodology, (2) developing and applying new tools, and (3) `proving' the methodology by undertaking `industrial strength' design examples. The work presented here is neither a beginning nor an end in the development of a complete top-down, constraint-driven design methodology, but rather a step in its development. This work is divided into three parts. Chapter 2 presents the design methodology along with foundation material. Chapters 3-8 describe supporting concepts for the methodology, from behavioral simulation and modeling to circuit module generators. Finally, Chapters 9-11 illustrate the methodology in detail by presenting the entire design cycle through three large-scale examples. These include the design of a current source D/A converter, a Sigma-Delta A/D converter, and a video driver system. Chapter 12 presents conclusions and current research topics. A Top-Down, Constraint-Driven Design Methodology for Analog Integrated Circuits will be of interest to analog and mixed-signal designers as well as CAD tool developers.
