Indexed Register Addressing Mode | Computer Architecture

In this lecture, we explain the Indexed Register Addressing Mode in Computer Architecture and Organization (CAO) with clear concepts and examples. In indexed addressing mode, the effective address is calculated by adding the index register value to the address field of the instruction. This addressing mode is widely used for accessing arrays, tables, and sequential data structures efficiently in computer systems. The lecture includes step-by-step explanation and numerical examples for better understanding. 📘 Topics Covered: What is Indexed Register Addressing Mode Formula for Effective Address Role of Index Register Indexed addressing with examples Accessing arrays using index register Advantages of indexed addressing mode 🎓 Best For: BSCS / BSIT / Software Engineering students Computer Architecture & Organization learners University and competitive exam preparation 🗣️ Language: Urdu / Hindi 📌 Learn how processors use index registers for efficient memory access.
