PREFACE:

In the four years since the eighth edition of this book was published, the field has seen continued innovations and improvements.

 In this new edition, I try to capture these changes while maintaining a broad and comprehensive coverage of the entire field.

 To begin this process of revision, the eighth edition of this book was extensively reviewed by a number of professors who teach the subject and by professionals working in the field.

 The result is that, in many places, the narrative has been clarified and tightened, and illustrations have been improved.

 Beyond these refinements to improve pedagogy and user-friendliness, there have been substantive changes throughout the book.

 Roughly the same chapter organization has been retained, but much of the material has been revised and new material has been added.

This book is about the structure and function of computers. Its purpose is to present, as clearly and completely as possible, the nature and characteristics of modern-day computer systems. This task is challenging for several reasons. 

First, there is a tremendous variety of products that can rightly claim the name of computer, from single-chip microprocessors costing a few dollars to supercomputers costing tens of millions of dollars.

 Variety is exhibited not only in cost but also in size, performance, and application. Second, the rapid pace of change that has always characterized computer technology continues with no letup.

 These changes cover all aspects of computer technology, from the underlying integrated circuit technology used to construct computer components to the increasing use of parallel organization concepts in combining those components.

 In spite of the variety and pace of change in the computer field, certain fundamental concepts apply consistently throughout.

 The application of these concepts depends on the current state of the technology and the price/performance objectives of the designer. 

The intent of this book is to provide a thorough discussion of the fundamentals of computer organization and architecture and to relate these to contemporary design issues.

 The subtitle suggests the theme and the approach taken in this book. It has always been important to design computer systems to achieve high performance, but never has this requirement been stronger or more difficult to satisfy than today. 

All of the basic performance characteristics of computer systems, including processor speed, memory speed, memory capacity, and interconnection data rates, are increasing rapidly. Moreover, they are increasing at different rates. 

This makes it difficult to design a balanced system that maximizes the performance and utilization of all elements. Thus, computer design increasingly becomes a game of changing the structure or function inone area to compensate for a performance mismatch in another area. 

We will see this game played out in numerous design decisions throughout the book. A computer system, like any system, consists of an interrelated set of components. 

The system is best characterized in terms of structure—the way in which components are interconnected, and function—the operation of the individual components. Furthermore, a computer’s organization is hierarchical.

 Each major component can be further described by decomposing it into its major subcomponents and describing their structure and function.
