嵌入式系统应用现状及发展趋势概述

The Application and Development Trend of Embedded Systems

嵌入式系统自上世纪七十年代问世以来，先后经历了单芯片可编程控制器、嵌入式CPU结合简单操作系统、专用嵌入式操作系统三个标志性发展阶段．现在正朝着与Internet相结合的方向发展。嵌入式系统具有高效性、稳定性、可靠性、节能性等特点，其应用目前主要集中在消费类电子、通信、医疗、安全等行业。随着嵌入式系统进一步的系统化、人性化、网络化，嵌入式产品必将渗入到人们生活的更多方面中，在科技进步以及人民生活中发挥更加重要的作用。

Embedded systems which came out at 1970＇s, successively live with three indicated seedtimes： single chip programming controller,embedded CPU with simple OS, operating systems especially for embedded systems. Now, they are developing on the way of banded with Internet.The embedded systems,which are high efficient, steady, credible and less consuming, are now mostly used in consumption electronic,communications,medical treatment, security and so on. As the embedded systems are becoming more systematic, available,network banded,they will full of our life and play a more important pole in advancement of science and technology.
