"Relaxed and informal, almost conversational, this writing style makes for comfortable reading that should appeal to everyone while breaking the tension of diving into the complexities of a modern multi-purpose microcontroller."
-Andrew Mason, Michigan State University, East Lansing, USA

"The authors are obviously authorities on the subject, and this shows clearly. The text is clearly written and easy to follow, with examples and analogies used to make understanding easier. Using Keil and the Tiva Launchpad should make it pretty easy to get the examples up and running on an actual Cortex-M as well as using a simulator."
-Craig A. Evans, University of Leeds, UK

"This book fills a void in the computer science literature."
-Don Evans, Southern Methodist University, Dallas, Texas, USA

"This text retains the ease of using the ARM7TDMI while moving the student [or reader] into the more capable Cortex-M4. ...The addition of the Cortex-M4 makes this a much stronger text."
-Ralph Tanner, Western Michigan University, Kalamazoo, USA

"Assembly language programming is still the best way to learn about the internals of processors and this is one of a very few books that teaches that skill for ARM processors. It covers the necessary material in a well-organized manner. Updated for newer versions of ARM processors, it adds good material on floating-point arithmetic that was missing from the first edition."
-Ronald W. Mehler, California State University, Northridge, USA

"In general, this book contains most of the content that I generally cover in my introduction to computer organization course. It contains very nice exercises at the end of each chapter, and that is a plus when generating questions to help students grasp the concepts. ...I look forward to a second edition, because I plan to continue using this book."
-Rose M. Lowe, Clemson University, South Carolina, USA
