2、機(jī)相比始終沒(méi)有太大優(yōu)勢(shì),成本上與32位系統(tǒng)相比也沒(méi)有什么優(yōu)勢(shì),未來(lái)一段時(shí)間嵌入式微控制器的發(fā)展方向必然是32位系統(tǒng)?;贏RM體系結(jié)構(gòu)的32位系統(tǒng)占領(lǐng)了32位嵌入式系統(tǒng)的大部分分額,但長(zhǎng)期以來(lái),基于ARM體系結(jié)構(gòu)的32位系統(tǒng)僅在嵌入式式系統(tǒng)的高端(通訊領(lǐng)域、PDA)等場(chǎng)合使用,要么以專用芯片的面貌出現(xiàn),要么以位處理器的廟貌出現(xiàn),并沒(méi)有出現(xiàn)性價(jià)比高的通用的微控制器。PHILIPS發(fā)現(xiàn)了這個(gè)空當(dāng),推出了性價(jià)比很高LPC2000系列微控制器,讓更多的嵌入式系統(tǒng)具有32位的處理能力。這也預(yù)示著32位系統(tǒng)
3、即將成為嵌入式系統(tǒng)的主流?;贏RM體系結(jié)構(gòu)的芯片在中國(guó)推廣已經(jīng)有好幾年了,關(guān)于ARM的圖書(shū)也出了不少。關(guān)于ARM的圖書(shū)主要有以下幾類:1.關(guān)于ARM內(nèi)核的圖書(shū),主要讀者是芯片設(shè)計(jì)者,內(nèi)容主要是介紹芯片設(shè)計(jì)的。2.芯片應(yīng)用類圖書(shū),主要是芯片的生產(chǎn)商或代理商編寫(xiě),主要讀者為應(yīng)用工程師。3.開(kāi)發(fā)板類圖書(shū),主要介紹相應(yīng)的ARM開(kāi)發(fā)板,給應(yīng)用者一些參考。以上3類圖書(shū)的側(cè)重點(diǎn)都不是ARM應(yīng)用開(kāi)發(fā)教學(xué),用于大學(xué)本科教學(xué)不太適合。為了方便高等院校教學(xué)方便,筆者編寫(xiě)了這本教材。不過(guò),因?yàn)榍度胧较到y(tǒng)牽涉的知識(shí)太廣
4、,一本教材無(wú)法深入論述。為此,筆者還會(huì)推出多本被套圖書(shū)以便學(xué)生知識(shí)擴(kuò)展。--1廣州周立功單片機(jī)發(fā)展有限公司Tel:(020)38730916387309173873097638730977Fax:38730925目錄第1章嵌入式系統(tǒng)概述·······························································································11.1嵌入式系統(tǒng)····························
