Computer Organization & Architecture (COA) - YouTube

Computer Organization & Architecture Course Overview

• Core Definitions:
  • Computer Organization: Focuses on the structural relationship of computer systems.
  • Computer Architecture: Focuses on the functional behavior of computer systems.
• Course Purpose: Designed for college/university students and exam aspirants (specifically targeting high weightage in the GATE exam).
• Key Curriculum Topics:
  • Architecture & Classification: Introduction to computer architecture types.
  • Memory: Interfacing, hierarchy, cache mapping (direct, associative, set-associative), and secondary memory.
  • Organization: Machine instructions, addressing modes, ALU, data-path, and control units (hard-wired vs. microprogrammed).
  • I/O Interfacing: Isolated vs. memory-mapped I/O; transmission modes (programmed, interrupt-driven, DMA).
  • Instruction Pipelining: Hazards, branch prediction, and speculative execution.
  • Number Systems: Bases, complementary systems, signed representation (overflow, sign bit extension), error detection/correction codes, and floating-point representation (IEEE standards).
  • Arithmetic Operations: Booth’s multiplication, restoring and non-restoring division.
• Study Materials: Includes numerical problems from previous year questions (PYQs) to assist exam preparation.
