Clements has a gift for conveying highly complex, technical information in an exceptionally clear and readable manner. Clements writing style is very student oriented, and stresses the basics of 68000 ASL while also covering the latest information on ASL later generation chips.

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.

Microprocessors and Microcomputer-Based System Design, Second Edition, builds on the concepts of the first edition. It discusses the basics of microprocessors, various 32-bit microprocessors, the 8085 microprocessor, the fundamentals of peripheral interfacing, and Intel and Motorola microprocessors. This edition includes new topics such as floating-point arithmetic, Program Array Logic, and flash memories. It covers the popular Intel 80486/80960 and Motorola 68040 as well as the Pentium and PowerPC microprocessors. The final chapter presents system design concepts, applying the design principles covered in previous chapters to sample problems.

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
