"This text is designed to provide 'hands-on' experience to students to help them develop an understanding of the hardware components of a microprocessor and the role of software in programming and interfacing aspects of the microprocessor. An 8-bit microprocessor, due to its simpler instruction set and architecture, is an ideal IC chip for providing the students with a solid foundation for micro-processors, their principles and applications. The concepts of all state-of-the-art processors can be understood easily, once the basics of the 8085 are understood. Today's sophisticated microprocessors have a semblance of 8085. The presentation style adopted in this book in a way is unique. It is a student-friendly text, written as conversation between the teacher and the students. The book lucidly explains the various programming examples in assembly language with a view to enabling students to develop microprocessor-based industrial application projects. Application programs developed in the book are based on the popular microprocessor kit, namely SDA-85. The book is suitable for both diploma and degree level students pursuing courses in Electronics and Electrical Engineering, Electronics and Communication Engineering and Information and Communication Technology."
