This document discusses multi-core processors. It begins by defining a multi-core processor as a single computing component with two or more independent processing units, or cores, that work together in parallel. It then covers different multi-core architectures including dual-core, quad-core, and those with shared caches. Performance analysis shows advantages like improved multi-tasking productivity and security due to shorter signal distances, though costs are higher and thermal management is more difficult than single-core processors. Common applications include video editing, encoding, gaming and graphics.

CONTENTS

3. • A Multi-core processor is a single computing component
with two or more independent actual central processing
units .
• They are several mostly independent cores which work
together in parallel.
Introduction

4. •A Multi-core microprocessor is one which combines two or more
independent processors into a single package, often a single integrated
circuit.
• A Dual-core device contains only two independent microprocessors.
Multi core

5. Types of Cores
A Dual-core
processor
contains two
cores.
A Quad-core
processor
contains four
cores.

10. Performance Analysis

11. • Multi-tasking productivity.
• It will work faster for certain programs.
• PC security.
• The signals between different CPUs travel shorter
distances.
Advantages

12. •They get only 60-80% more speed.
•The speed that the computer works at depends on what the
user is doing with it.
•They cost more than single core processors.
•They are more difficult to manage thermally than lower-
density single-core processors.
Disadvantages

13. Applications
• Video editing.
• Encoding .
• 3D gaming.
• Powerful graphics solution.
