Description

---

Computers perform countless tasks ranging from the business critical to the recreational, but regardless of how differently they may look and behave, they're all amazingly similar in basic function. Once you understand how the microprocessor—or central processing unit (CPU)—works, you'll have a firm grasp of the fundamental concepts at the heart of all modern computing.

Inside the Machine, from the co-founder of the highly respected Ars Technica website, explains how microprocessors operate—what they do and how they do it. The book uses analogies, full-color diagrams, and clear language to convey the ideas that form the basis of modern computing. After discussing computers in the abstract, the book examines specific microprocessors from Intel, IBM, and Motorola, from the original models up through today's leading processors. It contains the most comprehensive and up-to-date information available (online or in print) on Intel’s latest processors: the Pentium M, Core, and Core 2 Duo. Inside the Machine also explains technology terms and concepts that readers often hear but may not fully understand, such as "pipelining," "L1 cache," "main memory," "superscalar processing," and "out-of-order execution."

Includes discussion of:
–Parts of the computer and microprocessor
–Programming fundamentals (arithmetic instructions, memory accesses, control flow instructions, and data types)
–Intermediate and advanced microprocessor concepts (branch prediction and speculative execution)
–Intermediate and advanced computing concepts (instruction set architectures, RISC and CISC, the memory hierarchy, and encoding and decoding machine language instructions)
–64-bit computing vs. 32-bit computing
–Caching and performance

Inside the Machine is perfect for students of science and engineering, IT and business professionals, and the growing community of hardware tinkerers who like to dig into the guts of their machines.

"This is, by far, the most well written text that I have seen on the subject of computer architecture. The writing is clear, logically organized, well illustrated, and is contemporary . . . A work that will be viewed as essential to any student or professional in need of education on the subject."
—John Stroman, Technical Account Manager, Intel

"Jon's approachable style, the full color diagrams, and his use of modern architectures to give example to theory, continue to delectate. Highly recommended."
—Robert Love, Chief Architect, Linux Desktop, Novell Corporation

"What we like about Inside the Machine is the way the book is constructed, leading the interested reader on to advanced concepts illustrated with some nice graphics . . . will give you a sound grounding in the ideas behind a modern CPU."
—The Inquirer

"Pretty geeky material, certainly, but Stokes knows his stuff, and, better yet, actually makes a lot of it interesting, even to lesser geeks like myself. I've enjoyed a number of his CPU pieces on Ars, dense as they are."
—MacWorld

"Book Tells All On Intel Processors"
—EE Times

"Stokes delves into the details of each design, highlighting their advantages and disadvantages. He gets into the technical aspects without being intimidating and does an excellent job of comparing one chips features versus alternatives taken in others."
—Electronic Design

"You won't get more detailed, in-depth explanations and descriptions of the most famous and popular computer architectures, or such a great introduction into microprocessor architecture as [Inside the Machine]."
—Dev Hardware

"The introduction that will get anyone ready to fully understand and appreciate the very detailed concepts presented in more advanced texts. . . Indeed, if you are at all involved, or simply interested, in the operations of computers, [Inside the Machine] is a must have."
—MacResearch.org

"The diagrams throughout are very clear, and it really lives up to its billing as an 'illustrated guide.'". . . This book may well be the best passport to the otherwise inaccessible city of transistors just below your fingertips."
—Technovelty

"For a complicated subject, the book is very readable with excellent diagrams, if you are a newbie or experienced enthusiast with a strong interest in knowing how microprocessors actually work—this is a great book for your library."
—PC Clubhouse

"It's the textbook you won't be selling back to the bookstore after you've finished the class. It's just that handy to have around. If you aren't going to school, buy a copy anyway. . . Ever wonder what really happens between the keyboard and the monitor? Pick up a copy of Jon Stokes' Inside the Machine and find out for yourself."
—CertForums

"It's a very readable text, which doesn't cross that common boundary between a regular read & the sort of book you have to study line by line to grasp the concepts it's trying to explain . . . full of lovely diagrams, with points explained well."
—Everyday Happenings of a Techie

"This book helped revive in me an interest in CPU architectures and I hope Jon will consider doing a sequel . . . Definitely a good buy."
