8085 Microprocessor Instruction Set and Assembly Fundamentals

Understanding how a CPU executes instructions at the lowest level is the foundation of computer engineering and embedded systems. This course guides you from the absolute basics of microprocessor architecture to writing and analyzing 8085 assembly language code through clear, written explanations. You will learn to: Understand the internal architecture, registers, and addressing modes of the 8085 microprocessor; Analyze data transfer, arithmetic, logical, branching, and machine control instructions; Write functional 8085 assembly language programs for basic operations; Decipher timing diagrams, machine cycles, and instruction execution phases; Apply your knowledge to solve conceptual multiple-choice questions and debug common code errors; Connect classic 8085 concepts to modern microcontrollers and embedded systems programming. The course begins with essential hardware terminology and register layouts before systematically breaking down each instruction group with clear text examples and review questions. This course is designed for students, hobbyists, and aspiring embedded systems engineers starting with zero prior assembly programming experience.
