Microprocessor Fundamentals: 8085 and 8086 Architecture

Understanding how computers process instructions at the hardware level is essential for anyone interested in low-level programming or electronics. This text-based course guides you through the foundational concepts of microprocessor design, instruction execution, and system interfacing. By studying these classic architectures, you will gain a deep appreciation of how software interacts directly with physical silicon. You will transition from basic digital logic concepts to reading and writing assembly language instructions, understanding register structures, and grasping how 8-bit and 16-bit chips paved the way for modern computing systems. What you'll learn: - Understand the core architecture, register organization, and internal structure of the 8085 microprocessor. - Write and analyze basic assembly language programs to perform arithmetic, logical, and data transfer operations. - Explain memory interfacing, timing diagrams, and interrupt handling mechanisms. - Compare the 8-bit 8085 design with the 16-bit 8086 architecture, noting key advancements in memory segmentation. - Connect foundational microprocessor concepts to modern computing paradigms and embedded systems. The course begins with fundamental terminology, binary logic, and basic CPU operations before diving into detailed architectural breakdowns. You will then explore instruction sets, memory mapping, and practical assembly programming through clear written explanations and structured code walk-throughs. This course is designed for absolute beginners, computer science students, and electronics enthusiasts. No prior experience with hardware programming or assembly language is required.
