Hyper Threading Technology

Introduction

• Hyper-threading is a technology developed by

Intel Corporation for it’s Xeon processors with

a 533 MHz system. It was released in March 2002.

• Hyper-threading technology, commonly referred to

as "HT Technology," enables the processor to

execute two threads, or sets of instructions, at the

same time.

• HT Technology converts a single physical

processor into two virtual processors.

• HT Technology is also present in all Pentium

4 processors with 800MHz CPU bus speed

(2.4 GHz up through 3.8 GHz) as well as

the Pentium 4 Extreme Edition and the

Dual-core Pentium Extreme Edition.

Dual Core Technology

Introduction

• In a Dual core processor each core handles

incoming data strings simultaneously to

improve efficiency.

• When one is executing the other can be

accessing the system bus or executing its own

code.

• To utilize a dual core processor, the operating

system must have simultaneous multi-

threading technology.

• Intel introduced the first dual core processors

(the Pentium D and Pentium Extreme

Edition).
