不像嵌入式微控制器只執(zhí)行面向工業(yè)應(yīng)用的有限功能，現(xiàn)代嵌入式系統(tǒng)是互連、富媒體的(利用網(wǎng)絡(luò)功能和圖形用戶(hù)接口)。《現(xiàn)代嵌入式計(jì)算(英文版)》講述當(dāng)代嵌入式計(jì)算系統(tǒng)的平臺(tái)架構(gòu)，這些嵌入式系統(tǒng)能夠驅(qū)動(dòng)普適、互連的設(shè)備(如移動(dòng)電話(huà)、數(shù)字照相機(jī)、智能家居系統(tǒng))。
intelatom處理器廣泛用于如電子閱讀器、連網(wǎng)電視、平板電腦、筆記本電腦這樣的設(shè)備，全書(shū)一開(kāi)始就討論嵌入式平臺(tái)架構(gòu)和專(zhuān)用于intelatom處理器的架構(gòu)，接下來(lái)分別討論系統(tǒng)啟動(dòng)、操作系統(tǒng)、功耗優(yōu)化、圖形和多媒體加速、網(wǎng)絡(luò)連通性、平臺(tái)調(diào)試。本書(shū)介紹了如何開(kāi)發(fā)嵌入式片上系統(tǒng)(soc)框架，既適合作為高校嵌入式計(jì)算課程的教材，也適合嵌入式系統(tǒng)設(shè)計(jì)人員及相關(guān)專(zhuān)業(yè)人員閱讀參考。
本書(shū)特色
采用基于主流pc芯片架構(gòu)的intel atom處理器學(xué)習(xí)嵌入式系統(tǒng)設(shè)計(jì)，并提供與其他平臺(tái)的對(duì)比分析。
設(shè)計(jì)面向支持游戲、車(chē)載信息娛樂(lè)系統(tǒng)、醫(yī)療記錄檢索、銷(xiāo)售點(diǎn)購(gòu)買(mǎi)、聯(lián)網(wǎng)、數(shù)字存儲(chǔ)以及其他零售、消費(fèi)和工業(yè)應(yīng)用的嵌入式處理器。
Peter Barry，現(xiàn)任Intel嵌入式與通信事業(yè)部主任工程師。他有20多年的從業(yè)經(jīng)歷，先后供職于Intel、BasicCommunications、 NortelNetworks和Tellabs公司，一直致力于嵌入式系統(tǒng)的研發(fā)工作，研發(fā)的處理器包括Z80、68K、PowerPC、ARM、XScale和Intel架構(gòu)系統(tǒng)，開(kāi)發(fā)了用于proprietaryRTOS、pSOS、VxWorks、WinCE和Linux的多個(gè)板級(jí)支持包。他還開(kāi)發(fā)出主要用于數(shù)據(jù)通信和電信以及工業(yè)應(yīng)用的多個(gè)協(xié)議棧和應(yīng)用程序。
