Mc68000 16 Bit Microprocessor

For Design Engineers, Software Architects & Computer Designers, a Guide to Completing Software Systems Using Motorola's MC68000 Family of Microprocessors

This important revision introduces both students and practicing computer professionals to the characteristics of the Motorola 68000 family of processors. It has been widely applauded in previous editions as a text that is practical, easy to read, and designed to educate readers on the concepts as well as applied theory. In addition to its use as a learning aid, the text serves as a valuable reference in which topics are organized according to function and importance for the design of programs, interfaces or systems. This Second Edition has been updated to cover the most recent, relevant advances and developments affecting the MC68000 family of microprocessors.

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.

In the last few years, a large number of books on microprocessors have appeared on the market. Most of them originated in the context of the 4-bit and the 8-bit microprocessors and their comparatively simple structure. However, the techno-logical development from 8-bit to 16-bit microprossors led to processor components with a substantially more complex structure and with an expanded functionality and also to an increase in the system architecture's complexity. This books takes this advancement into account. It examines 16-bit micro-processor systems and descrihes their structure, their behavior and their programming. The principles of computer or ganization are treated at the component level. This is done by means of a detailed examination of the characteristic functionali ty of microprocessors. Furthermore the interactions between hardware and software, that are typical of microprocessor technology, are introduced. Interfacing techniques are one of the focal points of these considerations. This puplication is organized as a textbook and is intended as a self-teaching course on 16-bit microprocessors for students of computer science and communications, design engineers and users in a wide variety of technical and scientific fields. Basic knowledge of boolean algebra is assumed. The choice of material is based on the 16-bit microprocessors that are currently available on the market; on the other hand, the presentation is not bound to anyone of these microprocessors.
