On Multi-core Processors

Introduction Multi core Multi core architecture Comparison of Different Architectures Performance analysis Advantages & Disadvantages Application

CONTENTS

• 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

•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

Types of Cores

A Dual-core processor contains two cores.

A Quad-core processor contains four cores.

Performance Analysis

• Multi-tasking productivity.

• It will work faster for certain programs.

• PC security.

• The signals between different CPUs travel shorter distances.

Advantages

•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

Applications

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