PREFACE Ce Microcomputers are found in all areas of modern society. They have become the workhorse of systems designers for products that range from simple special purpose systems to very complex networks. The range of applications varies from toys to advanced home and business computers. As a result, there is a critical need for a basic and thorough understand- ing of microcomputer principles on the part of everyone involved in any aspect of modern technical products, whether that involvement is in product development, manufacturing, or sales. It is the purpose of this book to provide this understanding to students, regardless of background or profession. While such an objective might seem impossible with some sub- jects, the microcomputer approach can [~ understood by anyone of average intelligence and reasoning ability. This is one of the principal advantages of microcomputer systems: they can be easily designed, built, and used. The organization of the book is built around information modules so that study can be tailored to the individual student s needs. It is divided into two major sections to correspond to the two major aspects of microcomputers: the first seven chapters are devoted to software development while the remaining chapters are devoted to hardware design. In these general categories, the early chapters of a section deal with fundamental information while the last two or three chapters of a section provide information for more advanced students. These sections can be read either together or independently to fit the student s information needs. These sections are described along with their information objectives as follows: Software Development Section Chapter 1. Basic Microcomputer Concepts. An introduction into the terminology, coding, structure, and operation of microcomputer systems. Chapter 2. Software Features of Microprocessors. An introduction to microcomputer elements, instructions, languages, and programs. Chapter 3. Microprocessor Instruction Sets. The meaning and use of a set of microproces- sor instructions. Chapter 4. Programming Methods. The basic techniques used in writing microcomputer programs. Chapter 5. Microcomputer Programs. The development and operation of typical micro- computer programs. Chapter 6. Advanced Software Techniques. The concepts of standard programming methodology and system data and file management techniques. Chapter 7. High-Level Language Programming. Covers BASIC as an example of pro- gramming in a high-level problem-oriented language. FUNDAMENTALS OF MICROCOMPUTER DESIGN V
