基于arm7的嵌入式家电控制系统的设计-------外文翻译,目前，在嵌入式系统应用领域中，不少人对什么是嵌入式系统不甚了解。有些人搞了十多年的单片机应用，不知道单片机就是一个最典型的嵌入式系统；也有些人在解释什么是嵌入式系统时，不是从定义出发，而是列举了嵌入式系统的一些特点，往往不知所云。因此，有必要从现代计算的发展历史，了解嵌入式系统的由来，从学科建设的角度来探讨嵌入式系统较...

目前，在嵌入式系统应用领域中，不少人对什么是嵌入式系统不甚了解。有些人搞了十多年的单片机应用，不知道单片机就是一个最典型的嵌入式系统；也有些人在解释什么是嵌入式系统时，不是从定义出发，而是列举了嵌入式系统的一些特点，往往不知所云。因此，有必要从现代计算的发展历史，了解嵌入式系统的由来，从学科建设的角度来探讨嵌入式系统较为准确的定义。
嵌入式系统诞生于微型机时代，嵌入式系统的嵌入性本质是将一个计算机嵌入到一个对象体系中去，这些是理解嵌入式系统的基本出发点。由于嵌入式计算机系统要嵌入到对象体系中，实现的是对象的智能化控制，因此，它有着与通用计算机系统完全不同的技术要求与技术发展方向。
通用计算机系统的技术要求是高速、海量的数值计算；技术发展方向是总线速度的无限提升，存储容量的无限扩大。 而嵌入式计算机系统的技术要求则是对象的智能化控制能力；技术发展方向是与对象系统密切相关的嵌入性能、控制能力与控制的可靠性。
嵌入式计算机系统则走上了一条完全不同的道路，这条独立发展的道路就是单芯片化道路。它动员了原有的传统电子系统领域的厂家与专业人士，
At present, the application of embedded system in the area, many people of what is not very understanding of embedded system. Some people engage in more than 10 years of SCM application, do not know the SCM is one of the most typical embedded system; also some people in the interpretation of what is the embedded system, not from the definition, it lists some characteristics of embedded systems, often unintelligible. Therefore, it is necessary from the development history of modern computing, embedded system, from a viewpoint of subject construction of embedded system more accurate definition.
Embedded system was born in microcomputer era, embedded systems embedded in nature is a computer into an object system, these are the basic starting point of understanding of embedded system. Because the embedded computer system is embedded into the object system, is the realization of the object of intelligent control, therefore, it has with a general purpose computer system completely different technical requirements and technology development direction.
A general purpose computer system technical requirements are high, massive numerical calculation; the direction of technology development is unlimited upgrade the bus speed, the unlimited expansion of storage capacity. Embedded computer system technical requirements is the object of intelligent control; technology development and the object is closely related to the embedded system performance, control and control of reliability.
Embedded computer system will embark on a completely different path, the
