Description

This book is organized into three parts. Part I deals with the software experiments - addition, subtraction, multiplication, code conversion etc. All the software programs are written in assembly language. Part II describes the hardware experiments. Some of the hardware experiments are designed with microcontroller kits and many are discussed with 89C51 microcontroller alone. Every experiment is written in such way that an experimenter need not require additional information to perform the experiment. In most of the experiments both assembly language and embedded ‘C’ programs are given. Part III deals with the complete projects.
