GATE CS - COMPUTER ORGANIZATION:Introduction to Computer Organization

Introduction to Computer Organization for GATE CS

GATE COA marks sit in instruction formats / addressing, pipelining hazards, and cache numericals. This page is the map; later chapters do the math.

Hardware vs architecture

ISA = programmer-visible instructions, registers, addressing. Organization = how a machine implements that ISA (datapath, pipeline, memory hierarchy).

Topics and where to go

1. Instruction Set Architecture — formats, addressing modes
2. CPU Design and Pipelining — hazards, speedup
3. Memory Hierarchy and Cache — tag/index/offset

Performance vocabulary: latency vs throughput; CPI; speedup = $T_{old}/T_{new}$.
