Hennessy and Patterson emphatically demonstrate why they are the doyens of this deep and shifting field. Computer architecture isn't an essential subject in the information age. You don't need the 4th edition of Computer Architecture''. The 4th edition is a classic encore that has been adapted beautifully to meet the rapidly changing constraints of 'late-CMOS-era' technology. The detailed case studies of real processor products are especially educational, and the text reads so smoothly that it is difficult to put down.
This book is a must-read for students and professionals alike! The 4th edition continues the tradition of presenting the latest in innovations with commercial impact, alongside the foundational con- cepts: This book is an excellent resource for anybody interested in learning the architec- tural concepts underlying real commercial products. Students gain unique insight into the factors influencing the shape of computer architecture design and the poten- tial research directions in the computer systems field.
The lessons that this new edition teaches will continue to be as relevant as ever for its readers. John L.

I am honored and privileged to write the foreword for the fourth edition of this most important book in computer architecture. In the first edition, Gordon Bell, my first industry mentor, predicted the book's central position as the definitive text for computer architecture and design.
He was right. I clearly remember the excitement generated by the introduction of this work.
Rereading it now, with significant extensions added in the three new editions, has been a pleasure all over again. No other work in computer architecture—frankly, no other work I have read in any field—so quickly and effortlessly takes the reader from igno- rance to a breadth and depth of knowledge.
This book is dense in facts and figures, in rules of thumb and theories, in examples and descriptions. It is stuffed with acronyms, technologies, trends, for- mulas, illustrations, and tables. And, this is thoroughly appropriate for a work on architecture. The architect's role is not that of a scientist or inventor who will deeply study a particular phenomenon and create new basic materials or tech- niques.
Nor is the architect the craftsman who masters the handling of tools to craft the finest details.
The architect's role is to combine a thorough understand- ing of the state of the art of what is possible, a thorough understanding of the his- torical and current styles of what is desirable, a sense of design to conceive a harmonious total system, and the confidence and energy to marshal this knowl- edge and available resources to go out and get something built. To accomplish this, the architect needs a tremendous density of information with an in-depth understanding of the fundamentals and a quantitative approach to ground his thinking.
That is exactly what this book delivers. As computer architecture has evolved—from a world of mainframes, mini- computers, and microprocessors, to a world dominated by microprocessors, and now into a world where microprocessors themselves are encompassing all the complexity of mainframe computers—Hennessy and Patterson have updated their book appropriately. The later editions focused on the details of the 80x86 and RISC processors, which had come to dominate the landscape.
This lat- est edition expands the coverage of threading and multiprocessing, virtualization. The first chapter, in less than 60 pages, introduces the reader to the taxono- mies of computer design and the basic concerns of computer architecture, gives an overview of the technology trends that drive the industry, and lays out a quan- titative approach to using all this information in the art of computer design.
The next two chapters focus on traditional CPU design and give a strong grounding in the possibilities and limits in this core area. The final three chapters build out an understanding of system issues with multiprocessing, memory hierarchy, and storage. Knowledge of these areas has always been of critical importance to the computer architect. In this era of system-on-a-chip designs, it is essential for every CPU architect.
Finally the appendices provide a great depth of understand- ing by working through specific examples in great detail. In design it is important to look at both the forest and the trees and to move easily between these views. As you work through this book you will find plenty of both.
The result of great architecture, whether in computer design, building design or textbook design, is to take the customer's requirements and desires and return a design that causes that customer to say, "Wow, I didn't know that was possible.

I Introduction C. Through four editions of this book, our goal has been to describe the basic princi- ples underlying what will be tomorrow's technological developments. Our excitement about the opportunities in computer architecture has not abated, and we echo what we said about the field in the first edition: It's a discipline of keen intellectual interest, requiring the balance of marketplace forces to cost-performance-power, leading to glorious failures and some notable successes.
Our primary objective in writing our first book was to change the way people learn and think about computer architecture.
We feel this goal is still valid and important. The field is changing daily and must be studied with real examples and measurements on real computers, rather than simply as a collection of defini- tions and designs that will never need to be realized. We offer an enthusiastic welcome to anyone who came along with us in the past, as well as to those who are joining us now. Either way, we can promise the same quantitative approach to, and analysis of, real systems. As with earlier versions, we have strived to produce a new edition that will continue to be as relevant for professional engineers and architects as it is for those involved in advanced computer architecture and design courses.
As much as its predecessors, this edition aims to demystify computer architecture through an emphasis on cost-performance-power trade-offs and good engineering design.
We believe that the field has continued to mature and move toward the rigorous quantitative foundation of long-established scientific and engineering disciplines. The fourth edition of Computer Architecture: A Quantitative Approach may be the most significant since the first edition. Shortly before we started this revision, Intel announced that it was joining IBM and Sun in relying on multiple proces- sors or cores per chip for high-performance designs.
As the first figure in the book documents, after 16 years of doubling performance every 18 months, sin-. This fork in the computer architecture road means that for the first time in history, no one is building a much faster sequential processor. If you want your program to run significantly faster, say, to justify the addition of new features, you're going to have to parallelize your program.
Hence, after three editions focused primarily on higher performance by exploiting instruction-level parallelism ILP , an equal focus of this edition is thread-level parallelism TLP and data-level parallelism DLP.
This historic shift led us to change the order of the chapters: The changing technology has also motivated us to move some of the content from later chapters into the first chapter.
Because technologists predict much higher hard and soft error rates as the industry moves to semiconductor processes with feature sizes 65 nm or smaller, we decided to move the basics of dependabil- ity from Chapter 7 in the third edition into Chapter 1. As power has become the dominant factor in determining how much you can place on a chip, we also beefed up the coverage of power in Chapter 1.
Of course, the content and exam- ples in all chapters were updated, as we discuss below. In addition to technological sea changes that have shifted the contents of this edition, we have taken a new approach to the exercises in this edition. It is sur- prisingly difficult and time-consuming to create interesting, accurate, and unam- biguous exercises that evenly test the material throughout a chapter.
Alas, the Web has reduced the half-life of exercises to a few months. Rather than working out an assignment, a student can search the Web to find answers not long after a book is published. Hence, a tremendous amount of hard work quickly becomes unusable, and instructors are denied the opportunity to test what students have learned. To help mitigate this problem, in this edition we are trying two new ideas. First, we recruited experts from academia and industry on each topic to write the exercises.
This means some of the best people in each field are helping us to cre- ate interesting ways to explore the key concepts in each chapter and test the reader's understanding of that material. Second, each group of exercises is orga- nized around a set of case studies. Our hope is that the quantitative example in each case study will remain interesting over the years, robust and detailed enough to allow instructors the opportunity to easily create their own new exercises, should they choose to do so.
Key, however, is that each year we will continue to release new exercise sets for each of the case studies. These new exercises will have critical changes in some parameters so that answers to old exercises will no longer apply. Another significant change is that we followed the lead of the third edition of Computer Organization and Design COD by slimming the text to include the material that almost all readers will want to see and moving the appendices that.
There were many reasons for this change:. Students complained about the size of the book, which had expanded from pages in the chapters plus pages of appendices in the first edition to chapter pages plus appendix pages in the second edition and then to chapter pages plus pages in the paper appendices and pages in online appendices.
At this rate, the fourth edition would have exceeded pages both on paper and online! Similarly, instructors were concerned about having too much material to cover in a single course.
As was the case for COD, by including a CD with material moved out of the text, readers could have quick access to all the material, regardless of their ability to access Elsevier's Web site. Hence, the current edition's appendices will always be available to the reader even after future editions appear.
This flexibility allowed us to move review material on pipelining, instruction sets, and memory hierarchy from the chapters and into Appendices A, B, and C. The advantage to instructors and readers is that they can go over the review material much more quickly and then spend more time on the advanced top- ics in Chapters 2, 3, and 5. It also allowed us to move the discussion of some topics that are important but are not core course topics into appendices on the CD.
In this edition we have 6 chapters, none of which is longer than 80 pages, while in the last edition we had 8 chapters, with the longest chapter weighing in at pages.
This package of a slimmer core print text plus a CD is far less expensive to manufacture than the previous editions, allowing our publisher to signifi- cantly lower the list price of the book. With this pricing scheme, there is no need for a separate international student edition for European readers.
Yet another major change from the last edition is that we have moved the embedded material introduced in the third edition into its own appendix, Appen- dix D.
We felt that the embedded material didn't always fit with the quantitative evaluation of the rest of the material, plus it extended the length of many chapters that were already running long. We believe there are also pedagogic advantages in having all the embedded information in a single appendix. This edition continues the tradition of using real-world examples to demon- strate the ideas, and the "Putting It All Together" sections are brand new; in fact, some were announced after our book was sent to the printer.
As before, we have taken a conservative approach to topic selection, for there are many more interesting ideas in the field than can reasonably be covered in a treat- ment of basic principles. We have steered away from a comprehensive survey of every architecture a reader might encounter. Instead, our presentation focuses on core concepts likely to be found in any new machine. The key criterion remains that of selecting ideas that have been examined and utilized successfully enough to permit their discussion in quantitative terms.
Our intent has always been to focus on material that is not available in equiva- lent form from other sources, so we continue to emphasize advanced content wherever possible. Indeed, there are several systems here whose descriptions cannot be found in the literature.
Readers interested strictly in a more basic introduction to computer architecture should read Computer Organization and Design: Chapter 1 has been beefed up in this edition. It includes formulas for static power, dynamic power, integrated circuit costs, reliability, and availability. We go into more depth than prior editions on the use of the geometric mean and the geo- metric standard deviation to capture the variability of the mean.
Our hope is that these topics can be used through the rest of the book. In addition to the classic quantitative principles of computer design and performance measurement, the benchmark section has been upgraded to use the new SPEC suite.
Our view is that the instruction set architecture is playing less of a role today than in , so we moved this material to Appendix B. It still uses the MIPS64 architecture.
Chapters 2 and 3 cover the exploitation of instruction-level parallelism in high-performance processors, including superscalar execution, branch prediction, speculation, dynamic scheduling, and the relevant compiler technology.
As men- tioned earlier, Appendix A is a review of pipelining in case you need it. Chapter 3 surveys the limits of ILR New to this edition is a quantitative evaluation of multi- threading. While the last edition contained a great deal on Itanium, we moved much of this material to Appendix G, indicating our view that this architecture has not lived up to the early claims.
Given the switch in the field from exploiting only ILP to an equal focus on thread- and data-level parallelism, we moved multiprocessor systems up to Chap- ter 4, which focuses on shared-memory architectures. The chapter begins with the performance of such an architecture. It then explores symmetric and distributed-memory architectures, examining both organizational principles and performance.
Topics in synchronization and memory consistency models are. The example is the Sun Tl "Niagara" , a radical design for a commercial product. It reverted to a single-instruction issue, 6-stage pipeline microarchitec- ture. It put 8 of these on a single chip, and each supports 4 threads. Hence, soft- ware sees 32 threads on this single, low-power chip.
As mentioned earlier, Appendix C contains an introductory review of cache principles, which is available in case you need it. This shift allows Chapter 5 to start with 11 advanced optimizations of caches. The chapter includes a new sec- tion on virtual machines, which offers advantages in protection, software man- agement, and hardware management. The example is the AMD Opteron, giving both its cache hierarchy and the virtual memory scheme for its recently expanded bit addresses.
Chapter 6, "Storage Systems," has an expanded discussion of reliability and availability, a tutorial on RAID with a description of RAID 6 schemes, and rarely found failure statistics of real systems.
Rather than go through a series of steps to build a hypothetical cluster as in the last edition, we evaluate the cost, performance, and reliability of a real cluster: Free Computer Architecture Books.
