Foundations of Microprocessors 8085/8086 and Microcontroller 8051

Understanding how hardware and software interact at the lowest level is the key to mastering modern embedded systems. This course introduces you to the foundational architectures that shaped computing: the 8085 and 8086 microprocessors, and the 8051 microcontroller. By reading through these structured text lessons, you will transition from a complete beginner to confidently reading assembly language, understanding memory organization, and explaining how CPUs execute instructions. You will gain a clear mental model of registers, buses, and hardware interfacing that applies directly to modern chip design. What you'll learn: - Understand the fundamental differences between microprocessors and microcontrollers. - Analyze the internal architectures, registers, and pin configurations of the 8085, 8086, and 8051. - Write and interpret basic Assembly language instructions for arithmetic and logical operations. - Explain memory segmentation, addressing modes, and data transfer schemes. - Explore peripheral interfacing concepts, interrupts, and input/output programming. - Relate these classic architectures to modern computing paradigms and embedded systems. The course begins with core terminology and the basic physics of computing before guiding you step-by-step through CPU cycles, memory mapping, and practical assembly examples. Designed specifically for beginners, engineering students, and electronics enthusiasts, this course requires no prior background in hardware programming.
