PrefaceWhy publish yet another book on digital design and computer architecture? There are dozens of good books in print on digital design. There are also several good books about computer architecture, especially the classic texts of Patterson and Hennessy. This book is unique in its treatment in that it presents digital logic design from the perspective of computer architecture, starting at the beginning with 1's and 0's, and leading students through the design of a MIPS microprocessor.
We particularly like their coverage of the MIPS architecture and microarchitecture because MIPS is a commercially successful microprocessor architecture, yet it is simple enough to clearly explain and build in an introductory class. Because our class has no prerequisites, the first half of the semester is dedicated to digital design, which is not covered by COD. Other universities have indicated a need for a book that combines digital design and computer architecture.
We have undertaken to prepare such a book. We believe that building a microprocessor is a special rite of passage for engineering and computer science students. The inner workings of a processor seem almost magical to the uninitiated, yet prove to be straightforward when carefully explained. Digital design in itself is a powerful and exciting subject. Assembly language programming unveils the inner language spoken by the processor.
Microarchitecture is the link that brings it all together. This book is suitable for a rapid-paced, single-semester introduction to digital design and computer architecture or for a two-quarter or two-semester sequence giving more time to digest the material and experiment in the lab.
The material is usually taught at the sophomore-or junior-year level, but may also be accessible to bright freshmen who have some programming experience. Instructors from qualified universities can access free Synplicity tools for use in their classroom and laboratories.
More details are available at the instructor site. Details on the sample lab materials are also provided here. We have found that this is immensely useful in the learning and debugging process. Synplicity has generously agreed to donate Synplify Pro to qualified universities and will provide as many licenses as needed to fill university labs.
Instructors should visit the instructor Web page for this text for more information on how to request Synplify Pro licenses. For additional information on Synplicity and its other software, visit www. Links to the user's manual and an example file are available at the companion site textbooks. LABSThe companion site includes links to a series of labs that cover topics from digital design through computer architecture. Both of these powerful and competitively priced boards are available from www.
The boards contain FPGAs that can be programmed to implement student designs. Qualified universities may contact the Xilinx University Program to request a donation of the full Foundation tools.
Instructors may also choose to install the tools on lab machines. The labs include instructions on how to implement the projects on the Digilent's Spartan 3 Starter Board. The implementation step may be skipped, but we have found it of great value. The labs will also work with the XST synthesis tool, but we recommend using Synplify Pro because the schematics it produces give students invaluable feedback. We have tested the labs on Windows, but the tools are also available for Linux.
BUGSAs all experienced programmers know, any program of significant complexity undoubtedly contains bugs. So too do books. We have taken great care to find and squash the bugs in this book. However, some errors undoubtedly do remain. We will maintain a list of errata on the book's Web page.
Please send your bug reports to ddcabugs onehotlogic. Be sure to include your mailing address. We have taught from various editions of their book for many years. We appreciate their gracious support of this book and their permission to build on their microarchitectures.
Duane Bibby, our favorite cartoonist, labored long and hard to illustrate the fun and adventure of digital design. We also appreciate the enthusiasm of Denise Penrose, Nate McFadden, and the rest of the team at Morgan Kaufmann who made this book happen. Numerous reviewers have substantially improved the book. We believe that microprocessors are not only technically, economically, and socially important, but are also an intrinsically fascinating human invention. By the time you finish reading this book, you will know how to design and build your own microprocessor.
The skills you learn along the way will prepare you to design many other digital systems. We assume that you have a basic familiarity with electricity, some prior programming experience, and a genuine interest in understanding what goes on under the hood of a computer. This book focuses on the design of digital systems, which operate on 1's and 0's. We begin with digital logic gates that accept 1's and 0's as inputs and produce 1's and 0's as outputs.
We then explore how to combine logic gates into more complicated modules such as adders and memories. Then we shift gears to programming in assembly language, the native tongue of the microprocessor. Finally, we put gates together to build a microprocessor that runs these assembly language programs.
A great advantage of digital systems is that the building blocks are quite simple: just 1's and 0's. They do not require grungy mathematics or a profound knowledge of physics.
Instead, the designer's challenge is to combine these simple blocks into complicated systems. A microprocessor may be the first system that you build that is too complex to fit in your head all at once.
One of the major themes weaved through this book is how to manage complexity. Modern digital systems are built from millions or billions of transistors. No human being could understand these systems by writing equations describing the movement of electrons in each transistor and solving all of the equations simultaneously. You will need to learn to manage complexity to understand how to build a microprocessor without getting mired in a morass of detail. AbstractionThe critical technique for managing complexity is abstraction: hiding details when they are not important.
A system can be viewed from many different levels of abstraction. For example, American politicians abstract the world into cities, counties, states, and countries. A county contains multiple cities and a state contains many counties. When a politician is running for president, the politician is mostly interested in how the state as a whole will vote, rather than how each county votes, so the state is the most useful level of abstraction.
On the other hand, the Census Bureau measures the population of every city, so the agency must consider the details of a lower level of abstraction. Figure 1. At the lowest level of abstraction is the physics, the motion of electrons.
The behavior of electrons is described by quantum mechanics and Maxwell's equations. Our system is constructed from electronic devices such as transistors or vacuum tubes, once upon a time. These devices have well-defined connection points called terminals and can be modeled by the relationship between voltage and current as measured at each terminal.
By abstracting to this device level, we can ignore the individual electrons. The next level of abstraction is analog circuits, in which devices are assembled to create components such as amplifiers. Analog circuits input and output a continuous range of voltages. Digital circuits such as logic gates restrict the voltages to discrete ranges, which we will use to indicate 0 and 1.
In logic design, we build more complex structures, such as adders or memories, from digital circuits. Microarchitecture links the logic and architecture levels of abstraction. The architecture level of abstraction describes a computer from the programmer's perspective.
For example, the Intel IA architecture used by microprocessors in most personal computers PCs is defined by a set of instructions and registers memory for temporarily storing variables that the programmer is allowed to use.
Microarchitecture involves combining logic elements to execute the instructions defined by the architecture. Moving into the software realm, the operating system handles lowlevel details such as accessing a hard drive or managing memory. Finally, the application software uses these facilities provided by the operating system to solve a problem for the user. Thanks to the power of abstraction, your grandmother can surf the Web without any regard for the quantum vibrations of electrons or the organization of the memory in her computer.
This book focuses on the levels of abstraction from digital circuits through computer architecture. When you are working at one level of abstraction, it is good to know something about the levels of abstraction immediately above and below where you are working. For example, a computer scientist cannot fully optimize code without understanding the architecture for which the program is being written. A device engineer cannot make wise trade-offs in transistor design without understanding the circuits in which the transistors will be used.
We hope that by the time you finish reading this book, you can pick the level of abstraction appropriate to solving your problem and evaluate the impact of your design choices on other levels of abstraction.

Вернулся ли Дэвид. Она помнила его тело, прижавшееся к ее телу, его нежные поцелуи. Неужели все это был сон. Сьюзан повернулась к тумбочке. На ней стояли пустая бутылка из-под шампанского, два бокала… и лежала записка.
