If I am not mistaken, the book is called Computer Systems: A Programmer&#x27;s Perspective (CS:APP) by Randal E. Bryant and David R. O&#x27;Hallaron. It&#x27;s very nicely written, and 3rd edition just came out this year. Coursera also has an archive of a great course based on this book from University of Washington - &#x27;The Hardware&#x2F;Software Interface&#x27;.
