Microprocessor 2

Calculation is the main function of a computer. The central unit is responsible for executing the programs. The microprocessor is its integrated form. This component, since the announcement of its marketing in 1971, has not stopped breaking records in terms of computing power, price reduction and integration of functions (calculation of basic functions, storage with integrated controllers). It is present today in most electronic devices. Knowing its internal mechanisms and programming is essential for the electronics engineer and computer scientist to understand and master the operation of a computer and advanced concepts of programming. This first volume focuses more particularly on the first generations of microprocessors, that is to say those that handle integers in 4 and 8-bit formats. The first chapter presents the calculation function and reminds the memory function. The following is devoted to notions of calculation model and architecture. The concept of bus is then presented. Chapters 4 and 5 can then address the internal organization and operation of the microprocessor first in hardware and then software. The mechanism of the function call, conventional and interrupted, is more particularly detailed in a separate chapter. The book ends with a presentation of architectures of the first microcomputers for a historical perspective. The knowledge is presented in the most exhaustive way possible with examples drawn from current and old technologies that illustrate and make accessible the theoretical concepts. Each chapter ends if necessary with corrected exercises and a bibliography. The list of acronyms used and an index are at the end of the book.

Recent advances in LSI technology and the consequent availability of inexpensive but powerful microprocessors have already affected the process control industry in a significant manner. Microprocessors are being increasingly utilized for improving the performance of control systems and making them more sophisticated as well as reliable. Many concepts of adaptive and learning control theory which were considered impractical only 20 years ago are now being implemented. With these developments there has been a steady growth in hardware and software tools to support the microprocessor in its complex tasks. With the current trend of using several microprocessors for performing the complex tasks in a modern control system, a great deal of emphasis is being given to the topic of the transfer and sharing of information between them. Thus the subject of local area networking in the industrial environment has become assumed great importance. The object of this book is to present both hardware and software concepts that are important in the development of microprocessor-based control systems. An attempt has been made to obtain a balance between theory and practice, with emphasis on practical applications. It should be useful for both practicing engineers and students who are interested in learning the practical details of the implementation of microprocessor-based control systems. As some of the related material has been published in the earlier volumes of this series, duplication has been avoided as far as possible.

I am writing this book for my fellow students who are preparing for NET/GATE. This book contains to the point information about the microprocessor 8085 without going through the unnecessary details that are not relevant to your exam. I hope it will help you to go through the concepts and then apply these concepts to solve problems at the end.

The Book Is Aimed At Providing The Students A Detailed Knowledge Of Programming And Interfacing Of Intel 8085 And Peripherals. It Is Intended For Students Of Electrical / Electronics Engineering As Well As For Working Professionals Who Wish To Acquire Knowledge In This Area. Apart From Providing The Necessary Theoretical Details, Programming Examples Are Also Included For Most Of The Topics. The Text Also Contains Details Of Many Microprocessor Applications So As To Orient The Reader To Design His Own Microprocessor Based Solutions For Practical Problems. A Set Of Review Question Are Also Provided For Each Chapter.

This comprehensive and thoroughly updated text now in its second edition continues to provide the complete knowledge about the Intel's 8085 microprocessors, its programming and concept of interfacing of memory, input/output devices and programmable peripheral chips. Organized in four parts, Part I (Chapters 1-9) covers a review of the analog and digital signals as well as hardware and software related aspects of microprocessor 8085. Part II (Chapters 10 and 11) discusses memory and input-output concepts, analog to digital and digital to analog converters and various memory and IO address decoding techniques. Part III (Chapters 12-17) explains the programmable interfacing chips with extensive interfacing examples. Part IV (Chapters 18 and 19) presents a brief discussion on other 8-bit microprocessors along with 16 and 32-bit Intel Processors. Each topic has been supported with numerous examples that will help students apply the concepts to other microprocessors in the course at advanced level. This book is designed specifically for the undergraduate students of electronics and communication engineering, computer science and engineering, and information technology. New to this Edition: Chapters on "Architecture and Organization of Microprocessor" and "Instruction Set of 8085 Microprocessor" have been revised and modified substantially. Multiple choice questions have been added to all the chapters.

The Motorola MC68000 family of microprocessors is undoubtedly a revolu tionary set of devices. The MC68000 is the first advanced 16-bit microprocessor with a 32-bit internal architecture and the first with 16-megabyte, nonsegment ed, direct memory addressing. The processor's six basic addressing modes are equivalent to 14, when one considers all of the variations among these modes. Combined with the device's data and instruction types, the modes provide more than 1000 useful instructions. The book you are about to study has been developed as an aid to the hard ware designer and as a supplement to the Motorola seminars on the 68000 microprocessor. The text includes a detailed description of the MC68000 and two complete systems that show how this processor can be interfaced to the outside world. The book follows a "top-down" approach. A brief history of microprocessors is provided first. Chapter 2 details the MC68000 by describing its registers, control lines, and capabilities. Chapter 3 introduces a small MC68000-based system. Although this system is characterized in the book as hypothetical, it is indeed the Educational Computer Board, used in the various Motorola seminars. The addressing modes and instructions are explained in Chapter 4, which includes helpful hints on how instructions can be used. Chapter 5 provides an in-depth description of additional instructions and numerous examples. Chapter 6 discusses exception handling and interrupts.
