微处理器 microprocessors

微处理器 microprocessors(中文12000字,英文7000字)
在最初几年的微处理器，有几个工程师的教育和经验，在应用的微处理器技术。现在说，微处理器和微控制器已成为无孔不入的，在这么多设备，能使用它们已经成为几乎每个技术人员的要求。
   如今，微处理器和微控制器已成为两个最有力的工具，提供给科学家和工程师。微控制器已经嵌入在这么多的产品，这是很容易忽视的一个事实是，他们大大超过个人电脑。每年以百万计数量的个人电脑发货，但在过去每年有数10亿的微控制器出售，而且目前大多新设计的个人电脑都是为嵌入式应用。为每一台PC设计师，还有数千设计师用微控制器在嵌入式应用。嵌入式设计，近年来增长很快。这本书是为了让读者基本的设计和分析思路，以设计可靠的微控制器或微处理器为基础的系统。这本书里重点，是对实际问题的接口处理器到内存和输入/输出装置和基本的接口使用装置和扩展。一个主要目标，这本书是为了表明如何使设备本身有可靠的设计。而大多的目光已考虑到"设计质量的提高"。大部分的重点放在了对过程发生后，设计一个产品就完成了。设计缺陷,很困难是的在那些外部的设计。这些类型的质量问题，可以解决在设计阶段就减少相对较少的花费导致后面好多的维护费。不幸的是，有许多硬体设计和组织，由于种种原因，不知道意义和牺牲的是一个不可靠的设计。设计方法论，在这一案文，是为了解决这个问题。

During the early years of microprocessors, there were few engineers witheducation and experience in the applications of microprocessor technology.Now that microprocessors and microcontrollers have become pervasive in somany devices, the ability to use them has become almost a requirement formany technical people.
Today the microprocessor and the microcontroller have become two of themost powerful tools available to the scientist and engineer. Microcontrollershave been embedded in so many products that it is easy to overlook the factthat they greatly outnumber personal computers. Millions of PCs are shippedeach year, but billions of microcontrollers ship annually. While a great deal ofattention is given to personal computers, the vast majority of new designs arefor embedded applications. For every PC designer, there are thousands ofdesigners using microcontrollers in embedded applications. The number ofembedded designs is growing quickly. The purpose of this book is to give thereader the basic design and analysis skills to design reliable microcontroller ormicroprocessor based systems. The emphasis in this book is on the practicalaspects of interfacing the processor to memory and I/O devices, and the basicsof interfacing such a device to the outside world.
