内容简介
In the early days of computer science, the interactions of hardware, software, compilers, and operating system were simple enough to allow students to see an overall picture of how computers worked. With the increasing complexity of computer technology and the resulting specialization of knowledge, such clarity is often lost. Unlike other texts that cover only one aspect of the field, The Elements of Computing Systems gives students an integrated and rigorous picture of applied computer science, as its comes to play in the construction of a simple yet powerful computer system.Indeed, the best way to understand how computers work is to build one from scratch, and this textbook leads students through twelve chapters and projects that gradually build a basic hardware platform and a modern software hierarchy from the ground up. In the process, the students gain hands-on knowledge of hardware architecture, operating systems, programming languages, compilers, data structures, algorithms, and software engineering. Using this constructive approach, the book exposes a significant body of computer science knowledge and demonstrates how theoretical and applied techniques taught in other courses fit into the overall picture.Designed to support one- or two-semester courses, the book is based on an abstraction-implementation paradigm; each chapter presents a key hardware or software abstraction, a proposed implementation that makes it concrete, and an actual project. The emerging computer system can be built by following the chapters, although this is only one option, since the projects are self-contained and can be done or skipped in any order. All the computer science knowledge necessary for completing the projects is embedded in the book, the only pre-requisite being a programming experience.The book's web site provides all tools and materials necessary to build all the hardware and software systems described in the text, including two hundred test programs for the twelve projects. The projects and systems can be modified to meet various teaching needs, and all the supplied software is open-source.
作者简介
本书通过展现简单但功能强大的计算机系统之构建过程，为读者呈现了一幅完整、严格的计算机应用科学大图景。本书作者认为，理解计算机工作原理的最好方法就是亲自动手，从零开始构建计算机系统。
通过12个章节和项目来引领读者从头开始，本书逐步地构建一个基本的硬件平台和现代软件阶层体系。在这个过程中，读者能够获得关于硬件体系结构、操作系统、编程语言、编译器、数据结构、算法以及软件工程的详实知识。通过这种逐步构造的方法，本书揭示了计算机科学知识中的重要成分，并展示其它课程中所介绍的理论和应用技术如何融入这幅全局大图景当中去。全书基于“先抽象再实现”的阐述模式，每一章都介绍一个关键的硬件或软件抽象，一种实现方式以及一个实际的项目。完成这些项目所必要的计算机科学知识在本书中都有涵盖，只要求读者具备程序设计经验。本书配套的支持网站提供了书中描述的用于构建所有硬件和软件系统所必需的工具和资料，以及用于12个项目的200个测试程序。
全书内容广泛、涉猎全面，适合计算机及相关专业本科生、研究生、技术开发人员、教师以及技术爱好者参考和学习。
The Elements of Computing Systems是2005年由TheMITPress出版,作者NoamNisan。
