The Motorola MC 68000 family of microprocessors is used in many microcomputers ranging from single board development systems up to professional workstations. It continues to be employed in business and industrial applications. The second edition of this introduction has been totally revised to cover the latest advances in microprocessor technology.

Covering routines for the most popular machines - ATT computer, the Atari 68000, the Commodore Amiga and the Macintosh - this book takes readers through all aspects of assembly language programming in a step-by-step fashion. It provides a complete, graduated approach to the entire line of 68000's, giving examples and exercises for each step so that readers can acquire all of the necessary skills. Topics include the 68000 programmer's model, explanations of number systems, subroutines and advanced assembler concepts, such as external references, linking, debugging and macros.

A vast increase in running speed can be obtained when using programs written in assembly language, which in essence entails direct programming of the computer without using a high level built-in language such as BASIC. However, this can only be undertaken by someone who has a reasonable understanding of the microprocessor and some of the other hardware used in the computer, but it is not as difficult as one might think and this book tells the story

MICROPROCESSOR THEORY AND APPLICATIONS WITH 68000/68020 AND PENTIUM A SELF-CONTAINED INTRODUCTION TO MICROPROCESSOR THEORY AND APPLICATIONS This book presents the fundamental concepts of assembly language programming and system design associated with typical microprocessors, such as the Motorola MC68000/68020 and Intel® Pentium®. It begins with an overview of microprocessors—including an explanation of terms, the evolution of the microprocessor, and typical applications—and goes on to systematically cover: Microcomputer architecture Microprocessor memory organization Microprocessor Input/Output (I/O) Microprocessor programming concepts Assembly language programming with the 68000 68000 hardware and interfacing Assembly language programming with the 68020 68020 hardware and interfacing Assembly language programming with Pentium Pentium hardware and interfacing The author assumes a background in basic digital logic, and all chapters conclude with a Questions and Problems section, with selected answers provided at the back of the book. Microprocessor Theory and Applications with 68000/68020 and Pentium is an ideal textbook for undergraduate- and graduate-level courses in electrical engineering, computer engineering, and computer science. (An instructor’s manual is available upon request.) It is also appropriate for practitioners in microprocessor system design who are looking for simplified explanations and clear examples on the subject. Additionally, the accompanying Website, which contains step-by-step procedures for installing and using Ide 68k21 (68000/68020) and MASM32 / Olly Debugger (Pentium) software, provides valuable simulation results via screen shots.

For freshman/sophomore-level courses in Assembly Language Programming, Introduction to Computer Organization, and Introduction to Computer Architecture. Students using this text will gain an understanding of how the functional components of modern computers are put together and how a computer works at the machine language level. MIPS architecture embodies the fundamental design principles of all contemporary RISC architectures. By incorporating this text into their courses, instructors will be able to prepare their undergraduate students to go on to upper-division computer organization courses.

Using an integrated applications format, this book provides novice computer users a solid and complete foundation in both language programming and interfacing techniques. KEY TOPICS: The book explains each new idea and concept with a set of step-by-step instructions for its application in real life situations. Coverage is aimed at readers with no previous computer or digital experience.
