基于arm7的嵌入式家電控制系統(tǒng)的設計-------外文翻譯,目前，在嵌入式系統(tǒng)應用領域中，不少人對什么是嵌入式系統(tǒng)不甚了解。有些人搞了十多年的單片機應用，不知道單片機就是一個最典型的嵌入式系統(tǒng)；也有些人在解釋什么是嵌入式系統(tǒng)時，不是從定義出發(fā)，而是列舉了嵌入式系統(tǒng)的一些特點，往往不知所云。因此，有必要從現代計算的發(fā)展歷史，了解嵌入式系統(tǒng)的由來，從學科建設的角度來探討嵌入式系統(tǒng)較...

目前，在嵌入式系統(tǒng)應用領域中，不少人對什么是嵌入式系統(tǒng)不甚了解。有些人搞了十多年的單片機應用，不知道單片機就是一個最典型的嵌入式系統(tǒng)；也有些人在解釋什么是嵌入式系統(tǒng)時，不是從定義出發(fā)，而是列舉了嵌入式系統(tǒng)的一些特點，往往不知所云。因此，有必要從現代計算的發(fā)展歷史，了解嵌入式系統(tǒng)的由來，從學科建設的角度來探討嵌入式系統(tǒng)較為準確的定義。
嵌入式系統(tǒng)誕生于微型機時代，嵌入式系統(tǒng)的嵌入性本質是將一個計算機嵌入到一個對象體系中去，這些是理解嵌入式系統(tǒng)的基本出發(fā)點。由于嵌入式計算機系統(tǒng)要嵌入到對象體系中，實現的是對象的智能化控制，因此，它有著與通用計算機系統(tǒng)完全不同的技術要求與技術發(fā)展方向。
通用計算機系統(tǒng)的技術要求是高速、海量的數值計算；技術發(fā)展方向是總線速度的無限提升，存儲容量的無限擴大。 而嵌入式計算機系統(tǒng)的技術要求則是對象的智能化控制能力；技術發(fā)展方向是與對象系統(tǒng)密切相關的嵌入性能、控制能力與控制的可靠性。
嵌入式計算機系統(tǒng)則走上了一條完全不同的道路，這條獨立發(fā)展的道路就是單芯片化道路。它動員了原有的傳統(tǒng)電子系統(tǒng)領域的廠家與專業(yè)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
