I understand that these authors may be "living legends" in their fields - the text absolutely conveys a superior knowledge of the subject. However, the information is poorly organized and, overall, poorly conveyed.
The reading is extremely dense and difficult to follow. While information density is never a bad thing - dissecting vast knowledge that is organized and described poorly is a terrible exercise in frustration. In the creation of this text, the authors set themselves up for a magnificent challenge: to convey their superlative knowledge of computer architecture in a way others may learn from effectively. I believe the authors ultimately failed this challenge.
As a student, attempting to extract information from this book is extremely frustrating. Nearly every, single sentence reads somewhat like a vocabulary exercise - only the vocabulary and language is entirely relative to other densely worded and entirely relative bits of information within the text. If the authors intended this book to be stored within a piece of RAM and read by a machine I'm sure the text would be entirely useful. Unfortunately, this book is intended for human beings to construct a framework of knowledge. We do so by connecting new information with frameworks already established in reality. This text fails miserably to serve that purpose.
I do not wish to disrespect the authors' authority on the subject, nor do I wish to undermine their writing ability. Nevertheless, after quickly realizing complete frustration with this text I feel compelled, as well as obligated, to share my experience with it.
