Addressing Modes in Computer Organization | Effective Address Calculation With Examples | COA

Addressing Modes in Computer Organization define how the CPU locates operands during instruction execution. In this lecture, you will learn different addressing techniques such as Implied, Immediate, Register, Register Indirect, Direct, Indirect, Relative, Indexed, Base Register, and Auto Increment/Decrement with clear examples and effective address calculations. Understanding addressing modes is essential for mastering instruction formats, CPU organization, and assembly language programming.‪@tvnagarajutechnical9978‬ 📌 Topics Covered Introduction to Addressing Modes Effective Address (EA) calculation Implied Addressing Mode Immediate Addressing Mode Register & Register Indirect Mode Direct & Indirect Addressing Relative Addressing Mode Indexed & Base Register Addressing Auto-Increment / Auto-Decrement Mode Examples and comparisons 🎯 Useful for CSE / IT students, Computer Organization exams, GATE preparation, and interview revision. 📘 Based on Morris Mano – Computer System Architecture syllabus. 👍 Like | 🔔 Subscribe | 💬 Comment for doubts #AddressingModes #ComputerOrganization #COA #EffectiveAddress #InstructionExecution #IndexedAddressing #RelativeAddressing #GateCS #EngineeringLectures #CPUArchitecture
