Core GATE CSE Subjects 25 topics Moderate to high

Computer Organization

GATE CSE Computer Organization and Architecture — CPU, memory hierarchy, pipelining, and I/O.

Learning outcomes

  • Explain instruction cycle and addressing modes
  • Compute cache hits and AMAT at a basic level
  • Analyze a simple pipeline and stall
  • Name I/O and interrupt concepts asked in GATE

Overview

COA (Computer Organization) covers instruction sets, datapath, control, cache, pipelining, and I/O.

GATE loves numerical questions on cache mapping, pipeline speedup, and addressing modes.

Study this hub together with Digital Logic — many cache and ALU ideas assume that background.
