8085 Microprocessor Foundations: Architecture and Assembly Language

Understanding how a computer works at the silicon level is the key to becoming a better software engineer or hardware designer. This text-based course guides you through the foundational concepts of the 8085 microprocessor, demystifying how CPUs execute instructions. You will transition from seeing hardware as a black box to understanding registers, memory mapping, and timing diagrams. By reading detailed explanations and tracing code step-by-step, you will learn to write, debug, and optimize assembly language programs. What you'll learn: - Understand the internal architecture of the 8085 microprocessor, including registers, the ALU, and control units. - Analyze the 8085 instruction set to perform arithmetic, logical, and data transfer operations. - Write functional assembly language programs using systematic low-level programming techniques. - Map memory addresses and understand how the microprocessor interfaces with external devices. - Trace timing diagrams and machine cycles to see exactly how instructions execute over clock cycles. - Relate 8085 concepts to modern CPU design principles, including RISC-V and ARM architectures. The course begins with fundamental terminology and hardware concepts before moving into the core architecture of the 8085. From there, you will progress through the instruction set, step-by-step assembly programming exercises, and timing analysis. This course is designed for beginners, computer science students preparing for academic exams, and aspiring embedded systems engineers with no prior hardware experience.
