The microprocessor forms the core of modern digital and embedded systems and plays a vital role in the functioning of computers, automation systems, and electronic devices. Among early microprocessors, the 8085 Microprocessor holds great educational importance as it provides a strong foundation for understanding microprocessor architecture, programming, and interfacing concepts. This textbook, “EL-223: 8085 Microprocessor,” has been prepared to introduce students to the fundamentals of microprocessor systems in a simple and practical manner.
The book focuses on the architecture and operation of the 8085 Microprocessor. The contents include an introduction to microprocessors, internal architecture of the 8085, instruction set and addressing modes, assembly language programming. The concepts are explained with clear descriptions, diagrams, examples, and step-by-step programs to help students understand both theoretical principles and practical implementation.
This textbook aims to develop analytical thinking, problem-solving ability, and programming skills among undergraduate students. It will be useful for students, teachers, and beginners who wish to gain a clear and systematic understanding of microprocessor fundamentals and applications.
