深入理解计算机系统 英文版 第3版
作者：（美）兰德尔·E.布莱恩特（Randal E.Bryant），（美）大卫·R.奥哈拉伦
出版时间：2017年版
内容简介
本书是一本将计算机软件和硬件理论结合讲述的经典教材，内容涵盖计算机导论、体系结构和处理器设计等多门课程。本书*大的特点是为程序员描述计算机系统的实现细节，通过描述程序是如何映射到系统上，以及程序是如何执行的，使读者更好地理解程序的行为，找到程序效率低下的原因。和第2版相比，本版内容上*大的变化是，从以IA32和x86-64为基础转变为完全以x86-64为基础。主要更新如下：· 基于x86-64，大量地重写代码，首次介绍对处理浮点数据的程序的机器级支持。· 处理器体系结构修改为支持64位字和操作的设计。· 引入更多的功能单元和更复杂的控制逻辑，使基于程序数据流表示的程序性能模型预测更加可靠。· 扩充关于用GOT和PLT创建与位置无关代码的讨论，描述了更加强大的链接技术（比如库打桩）。· 增加了对信号处理程序更细致的描述，包括异步信号安全的函数等。· 采用*新函数，更新了与协议无关和线程安全的网络编程。
