Introduction to 8085 Microprocessor and Assembly Language

Every modern computing system relies on the core principles of microprocessor architecture. Understanding the classic 8085 processor is the most effective way to build a solid foundation in low-level programming, hardware interfacing, and computer engineering. This text-based course guides you through the inner workings of the 8085 microprocessor. You will transition from understanding basic silicon logic to writing functional assembly language programs and understanding how hardware components communicate. What you'll learn: Understand the internal architecture, registers, and pin diagram of the 8085 microprocessor; Master the 8085 instruction set, including data transfer, arithmetic, logical, and branching operations; Write and debug assembly language programs using clear, step-by-step code walkthroughs; Analyze timing diagrams, machine cycles, and instruction cycles to optimize program execution; Configure basic memory and I/O interfacing techniques to connect external devices; Relate classic 8085 architectural concepts to modern embedded systems and RISC-V architectures. The course begins with foundational definitions of microprocessors and binary logic, moving systematically through register structures, instruction sets, and assembly programming. You will then progress to topics like interrupts and peripheral interfacing, concluding with a look at how these concepts apply to modern microcontrollers. This course is designed for beginners, engineering students, and hobbyists with no prior hardware or assembly programming experience.
