Inside the Machine: An Illustrated Introduction to Microprocessors and Computer Architecture

Here are the few I've really enjoyed. Inside the Machine: An Illustrated Introduction to Microprocessors and Computer Architecture Explains how Microprocessors operate, going from operands and building up a lot of the execution tricks used, all whilst going through popular examples of CPUs (thee pentium chips, PowerPCs, etc), discussing their history, their specs, their capabilities, etc. Hardware and Support Support for Virtualization This one corners on useful, but it's short and it's free and unless you work in virtualization it probably won't be much use but I found it helpful in getting a grasp on what is actually happening. ------ Edit: Removed history books but, for anyone interested, the ones I listed previously were The Idea Factory, Valley of Genius, and Android: The Team that Built the Android OS
