Introduction to Microprocessors: Addressing Modes and Interfacing

To build efficient embedded systems or understand low-level computing, you must first grasp how a microprocessor communicates with the external world. This text-based course guides you through the fundamental architecture of microprocessors, focusing on how they organize memory, execute instructions, and interface with peripherals. You will transition from understanding basic hardware pins to conceptualizing complete processor systems. What you'll learn: 1. Understand core microprocessor architecture, registers, and internal bus structures. 2. Analyze various addressing modes to see how processors locate and manipulate data. 3. Explore memory interfacing techniques and decoding schemes to connect RAM and ROM. 4. Learn how input/output (I/O) interfacing works, including programmed I/O and interrupts. 5. Examine timing diagrams and instruction cycles that govern processor execution. 6. Relate classical microprocessor concepts to modern embedded architectures like RISC-V. The course starts with foundational definitions of processor pins and architecture before moving step-by-step into addressing modes, instruction sets, and practical interfacing logic. You will consolidate your learning through detailed written explanations, step-by-step memory mapping exercises, and self-assessment questions. This course is designed for beginners in electrical engineering, computer science, or digital electronics, with no prior microprocessor experience required.
