嵌入式計(jì)算系統(tǒng)設(shè)計(jì)原理

前言

Embedded computing is more important today than it was in 2000．when the first edition of this book appeared．Embedded processors are in even more products，ranging from toys tO airplanes．Systems-on-chips now use up to hundreds of CPUs．The cell phone is on its way to becoming the new standard computing platform．As my column in IEEE Computer in September 2006 indicated．there are at least a half-million embedded systems programmers in the World today,probably closer to 800,000．In mis edition I have tried to both update and revamp．One major change is mat the book now uses the TI TMS320C55xTM(C55x)DSP.I seriously rewrote the discussion of real-time scheduling．I have tried to expand on performance analysis as a theme at as many levels of abstraction as possible．Given the importance of multiorocessors in even the most mundane embedded systems，this edition also talks more genetaUy about hardware／software co-design and muItiorocessors．One ofthe changes in the field is that this material iS taught at lower and lowerlevels of the curriculum．What used to be graduate material is now upper-division undergraduate；some of this material Will percolate down to the sophomore levelin the foreseeable future．I think that you Can use subsets of this book tO cover both more advanced and more basic courses．Some advanced students may not need the background material of the earlier chapters and you Can spend more time on software performance analysis，scheduling，and multiprocessors．Vc'hen teaching introductory courses，software performance analysis is an alternative path to exploroing microprocessor architectures as well as software；such courses can concentrate on the first few chapters．The new Web site for this book and my other books is http：//www．waynewolf．us．On this site，yoU can find overheads for the material in this book，suggestions for labs．a(chǎn)nd links tO more information on embedded systems．

內(nèi)容概要

本書(shū)從組件技術(shù)的視角出發(fā)，介紹了嵌入式系統(tǒng)設(shè)計(jì)技術(shù)和技巧。本書(shū)第l版已被廣泛應(yīng)用于教學(xué)，可以說(shuō)在很大程度上引發(fā)了嵌入式系統(tǒng)課程的創(chuàng)立，并為實(shí)踐設(shè)計(jì)提供了寶貴指南。第2版根據(jù)最先進(jìn)的技術(shù)發(fā)展進(jìn)行了更新。不論是進(jìn)行軟硬件設(shè)計(jì)的研究人員、學(xué)生還是專家，都能從Wayne Wolf的集成化工程設(shè)計(jì)方法中獲益匪淺。    本書(shū)主要特點(diǎn)：    以實(shí)際芯片(ARM芯片和TI C55x DSP)為例，進(jìn)行相關(guān)設(shè)計(jì)技術(shù)和技巧的說(shuō)明，向讀者介紹如何將這些理論付諸于設(shè)計(jì)實(shí)踐。    在所有關(guān)鍵課題討論中都尤為強(qiáng)調(diào)現(xiàn)實(shí)中的設(shè)計(jì)實(shí)踐，從而為學(xué)生和設(shè)計(jì)人員提供了最先進(jìn)技術(shù)的指導(dǎo)。    對(duì)設(shè)計(jì)實(shí)踐中所必需的基本應(yīng)用技術(shù)進(jìn)行重點(diǎn)討論，幫助讀者在實(shí)際工作中熟練地設(shè)計(jì)大型的、復(fù)雜的嵌入式系統(tǒng)。
