嵌入式系统编程

嵌入式系统编程(中文3900字,英文2100字)
介绍
我认为全球市场上可能只有五类计算机。
——托马斯•华盛顿，IBM董事长，1943。
每个人都想家里有一台电脑，这是不需要理由的。
——肯•奥森，DEC总裁，1977。
令人吃惊的是，在最近的几十年内，电脑在人们的日常事务中使用的越来越多。如今在我们的家庭和办公室中，电脑的使用越来越多，比那些以电脑为生和工作的人的使用率还高。但计算机不会因此识别其用户。在这一章中，我们将解释什么是嵌入式系统以及他们的用处。我们还将介绍嵌入式编程的主题，并讨论什么使得软件编程的一种唯一形式。我们将解释为什么我们选择了C语言作为本书的编程语言，并且将描述示例中使用的一些硬件。
Programming Embedded Systems
Introduction
I think there is a world market for maybe five computers.
―—Thomas Watson, Chairman of IBM, 1943
There is no reason anyone would want a computer in their home.
―—Ken Olson, President of Digital Equipment Corporation, 1977
One of the more surprising developments of the last few decades has been the ascendance of computers to a position of prevalence in human affairs. Today there are more computers in our homes and offices than there are people who live and work in them. Yet many of these computers are not recognized as such by their users. In this chapter, we'll explain what embedded systems are and where they are found. We will also introduce the subject of embedded programming and discuss what makes it a unique form of software programming. We'll explain why we have selected C as the language for this book and describe the hardware used in the examples.
