Introduction to Microprocessors: 8085, 8086, and Computer Architecture

Have you ever wondered how computers process instructions at the lowest level of hardware? Understanding the foundational architecture of microprocessors is the key to mastering both hardware design and low-level software development. In this text-based course, you will journey from the basic definitions of mini and microcomputers to the inner workings of the classic 8085 and 8086 microprocessors. You will gain a solid mental model of registers, memory addressing, instruction sets, and how these legacy architectures laid the groundwork for modern computing systems. What you'll learn: - Define and distinguish between mini, micro, and mainframe computer systems. - Understand the internal architecture, registers, and bus structures of the 8085 microprocessor. - Explore the 8086 microprocessor, focusing on its 16-bit architecture and memory segmentation. - Analyze assembly language instruction sets and basic assembly programming models. - Compare classic CISC architectures with modern RISC-V and ARM processors. - Practice tracing instruction execution and memory mapping through written exercises. The course begins with foundational definitions and hardware concepts before diving deep into the specific register configurations and instruction sets of the 8085 and 8086. You will then explore how these classic designs transition into the modern era of processor architecture. This course is designed for absolute beginners, computer science students, and hardware enthusiasts with no prior experience in assembly language or computer engineering.
