8085 Microprocessor Fundamentals: Architecture and Assembly Programming

Understanding how computers process information at the hardware level is the key to becoming an exceptional low-level programmer or hardware engineer. The 8085 microprocessor serves as the perfect educational gateway to mastering hardware architecture and assembly language. This text-based course guides you from absolute hardware basics to writing your own assembly programs and understanding memory interfacing. You will build a strong mental model of CPU registers, timing diagrams, and instruction execution that applies directly to modern microcontrollers. What you'll learn: - Understand the internal architecture of the 8085 microprocessor, including registers, ALU, and control units. - Master the core 8085 instruction set to write efficient assembly language programs. - Analyze timing diagrams and machine cycles to understand how instructions execute step-by-step. - Explore memory and I/O interfacing techniques to connect microprocessors with external devices. - Map traditional 8085 concepts to modern embedded system architectures like ARM and RISC-V. - Practice debugging and writing assembly routines through structured written exercises and code walk-throughs. You will start with fundamental terminology, binary logic, and hardware definitions before exploring the core architecture. From there, you will progress through instruction categories, assembly programming techniques, and physical interfacing concepts. Designed for beginners in computer science, electrical engineering, or hobby programming, this course requires no prior hardware or assembly experience.
