描述

20世紀(jì)90年代后，進(jìn)一步開始了從“集成電路”級設(shè)計不斷轉(zhuǎn)向“集成系統(tǒng)”級設(shè)計。目前已進(jìn)入單片系統(tǒng)SOC(Systemo-nachip)設(shè)計階段，并開始進(jìn)入實用階段。這種設(shè)計方法不是把系統(tǒng)所需要用到的所有集成電路簡單地二次集成到1個芯片上，如果這樣實現(xiàn)單片系統(tǒng)，是不可能達(dá)到單片系統(tǒng)所要求的高密度、高速度、高性能、小體積、低電壓、低功耗等指標(biāo)的，特別是低功耗要求。單片系統(tǒng)設(shè)計要從整個系統(tǒng)性能要求出發(fā)，把微處理器、模型算法、芯片結(jié)構(gòu)、外圍器件各層次電路直至器件的設(shè)計緊密結(jié)合起來，并通過建立在全新理念上的系統(tǒng)軟件和硬件的協(xié)同設(shè)計，在單個芯片上完成整個系統(tǒng)的功能。有時也可能把系統(tǒng)做在幾個芯片上。因為，實際上并不是所有的系統(tǒng)都能在一個芯片上實現(xiàn)的;還可能因為實現(xiàn)某種單片系統(tǒng)的工藝成本太高，以至于失去商業(yè)價值。目前，進(jìn)入實用的單片系統(tǒng)還屬簡單的單片系統(tǒng)，如智能IC卡等。但幾個著名的半導(dǎo)體廠商正在緊鑼密鼓地研制和開發(fā)像單片PC這樣的復(fù)雜單片系統(tǒng)。
