Baldwin Toombs and my uncle, Carl E Langenhop both of whom encouraged me to become a scholar Preface A computer can be viewed from many different levels Many people are interested only in using applications such as word processing or games A computer programmer, however, often sees the computer as an instrument to create new applications software A high-level language programmer's image of the computer is provided by the language compiler, which gives the impression that the computer stores object types like integer, real, and array of char in named memory locations, calculates values of expressions, calls procedures, executes while loops, and so forth However, an actual computer works at even lower levels This book emphasizes the architectural level, that is, the level defined by the machine instructions that the processor can execute Assembly-language instructions translate directly into machinelanguage instructions, so that when you write an assembly-language program, you gain an understanding of how the computer works at the machine-language level Although this book emphasizes the assembly-language/machinelanguage level of computer operations, it also looks at other levels For instance, it describes how high-level language concepts such as if statements are realized at the machine level It discusses some of the functions of the operating system It briefly describes the logic gates that are used at the hardware level It also looks at how assembly language is translated into machine language To program effectively at any level, programmers must understand certain fundamental principles at the machine level These apply to most computer architectures Introduction to 80x86 Assembly Language and Computer Architecture teaches these fundamental concepts: memory addressing, CPU registers and their uses representation of data in a computer in numeric formats and as character strings instructions to operate on 2's complement integers instructions to operate on individual bits instructions to handle strings of characters instructions for branching and looping coding of procedures: transfer of control, parameter passing, local variables, and preserving the environment for the calling program The primary architecture covered is the Intel 80x86 CPU family used in many personal computers However, almost every chapter includes information about other architectures, or about different computer levels Programming in assembly language and studying related concepts in Introduction to 80x86 Assembly Language and Computer Architecture prepares the student to program effectively in any programming language, to pursue advanced studies in computer design and architecture, or to learn more about system details for specific computers Text Organization and Content Much of the material in this book is based on my previous book, Fundamentals of Assembly Language Programming Using the IBM PC and Compatibles While teaching this material through the years, I have increasingly come to the conclusion that an assembly language course is the best place to introduce computer architecture to most students This book reflects a stronger emphasis on architecture than on programming It also concentrates on general concepts as opposed to the details of a particular computer system The minimal prerequisite for my assembly language class is a good understanding of a structured high-level language Chapters 3 through 6 and Chapter 8 form the core of my one-semester course I normally cover Chapters 1-8 thoroughly, Chapter 9 quickly, and then choose topics from Chapters 10-12 depending on time and resources available For instance, I sometimes introduce floating-point operations via in-line assembly statements in a C++ program Style and Pedagogy The text primarily teaches by example A complete assembly-language program is presented very early, in Chapter 3, and its components are carefully examined at a level that the student is able to understand Subsequent chapters include many examples of assembly language code along with appropriate explanations of new or difficult concepts The text uses numerous figures and examples Many series of "before" and "after" examples are given for instructions Examples are included that illustrate the use of a debugger These examples give the student a stronger sense of what is happening inside the computer Exercises appear at the end of each section Short-answer exercises reinforce understanding of the material just covered, and programming exercises offer an opportunity to apply the material to assembly-language programs Chapter 11: Decimal Arithmetic Figure 11.1: Packed BCD to ASCII conversion Figure 11.2: ASCII to packed BCD conversion Figure 11.3:
