1.2.1 8086 Microprocessor | BIU Explained | Segment Registers + Examples | Part 1 | EngineeringBytes

Welcome back to our 8086 Microprocessor Full Course! In this video, we focus on the Bus Interface Unit (BIU) of 8086 Microprocessor, which is responsible for memory interfacing, instruction fetching, and address generation. This is a Part 1 lecture, where we deeply explain segment registers and address calculation with examples. In this video, you will learn: * What is Bus Interface Unit (BIU) in 8086 * Functions of BIU * Segment Registers → CS, DS, SS, ES * Role of Instruction Pointer (IP) * Address Generation in 8086 * Physical Address Calculation (Segment : Offset) * Examples of address calculation * Introduction to instruction queue This video is part of our **8086 Microprocessor series**, where we cover: This lecture is very important for understanding segmentation and memory organization, which are key topics in exams.
