ABSTRACT In the last few years, power dissipation has become an important design constraint, on par with performance, in the design of new computer systems. Whereas in the past, the primary job of the computer architect was to translate improvements in operating frequency and transistor count into performance, now power efficiency must be taken into account at every step of the design process. While for some time, architects have been successful in delivering 40% to 50% annual improvement in processor performance, costs that were previously brushed aside eventually caught up. The most critical of these costs is the inexorable increase in power dissipation and power density in processors. Power dissipation issues have catalyzed new topic areas in computer architecture, resulting in a substantial body of work on more power-efficient architectures. Power dissipation coupled with diminishing performance gains, was also the main cause for the switch from single-core to multi-core architectures and a slowdown in frequency increase. This book aims to document some of the most important architectural techniques that were invented, proposed, and applied to reduce both dynamic power and static power dissipation in processors and memory hierarchies. A significant number of techniques have been proposed for a wide range of situations and this book synthesizes those techniques by focusing on their common characteristics.

自己花了老多时间画的PCB封装库，包含了目前全部STC单片机封装类型。注意是Altium Designer Summer 2008格式模式的。

现在网上找到的pcb规则约束解释都不太全面，当然了，我的也不是全的，但是如果仅仅进行PCB的设计的话已经够用了。其中部分规则是在altium官网上面自己翻译下来的，如有翻译不周的地方尽情谅解。 最后声明！不喜勿下！不要下了之后觉得不值这么多分！
