Fundamentals of Digital Logic and Microcontrollers, 6th Edition

Preface

The fifth edition of the book covered basics of computer engineering and science from digital logic to the design of a complete microcomputer system using Intel 8086 and Motorola 68000. With the growing popularity of microcontrollers, it is now necessary to have a clear understanding of the basic principles of microcontrollers at the undergraduate level. Microcontrollers play an important role in the design of digital systems. They are found in a wide range of applications including office automation systems such as copiers and fax machines, consumer electronics such as microwave ovens, digital instruments, and robotics.

Hence, a typical microcontroller such as Microchip Technology's PIC18F is used to replace the 8086 and 68000 in this edition. Several PIC18F-based simple practical applications using C-language are provided. The sixth edition covers an enhanced version of both combinational and sequential logic design, basics of computer organization and microcontrollers.

Like the fifth edition, emphasis is given on the basic concepts. To cite an example, we clearly point out that computers understand only 0's and 1's. It is, therefore, important that students be familiar with binary numbers. Furthermore, we focus on the fact that computers can normally only add. Hence, all other arithmetic operations such as subtraction are performed via addition. This can be accomplished using two's-complement arithmetic for binary numbers. This topic is, therefore, also included along ...
