64 AND IA-32 ARCHITECTURES

2.1.9 The Intel

Pentium

M Processor (2003-Current)

The Intel Pentium M processor family is a high performance, low power mobile

processor family with microarchitectural enhancements over previous generations of

IA-32 Intel mobile processors. This family is designed for extending battery life and

seamless integration with platform innovations that enable new usage models (such

as extended mobility, ultra thin form-factors, and integrated wireless networking).

Its enhanced microarchitecture includes:

• Support for Intel Architecture with Dynamic Execution

• A high performance, low-power core manufactured using Intel’s advanced

process technology with copper interconnect

• On-die, primary 32-KByte instruction cache and 32-KByte write-back data cache

• On-die, second-level cache (up to 2 MByte) with Advanced Transfer Cache Archi-

tecture

• Advanced Branch Prediction and Data Prefetch Logic

• Support for MMX technology, Streaming SIMD instructions, and the SSE2

instruction set

• A 400 or 533 MHz, Source-Synchronous Processor System Bus

• Advanced power management using Enhanced Intel SpeedStep

technology

2.1.10 The Intel

Pentium

Processor Extreme Edition

(2005-Current)

The Intel Pentium processor Extreme Edition introduced dual-core technology. This

technology provides advanced hardware multi-threading support. The processor is

based on Intel NetBurst microarchitecture and supports SSE, SSE2, SSE3, Hyper-

Threading Technology, and Intel 64 architecture.
