Introduction
1 Introduction
The Intel® Core
TM
2 Extreme quad-core processor and Intel® Core
TM
2 quad processor
on 45-nanometer process technology for platforms based on Mobile Intel® 4 Series
Express Chipset Family is the first low-power, mobile quad-core processor based on the
Intel® Core™ microarchitecture.
In this document, the Intel Core
2 Extreme quad-core processor and Intel Core
2 quad
processor are referred to as the processor or quad-core processor and the Mobile Intel
4 Series Express Chipset is referred to as the (G)MCH.
Key features of the processor include:
• Quad-core mobile processor for mobile with enhanced performance
• Supports Intel® architecture with Intel® Wide Dynamic Execution
• Supports L1 cache-to-cache (C2C) transfer
• On-die, primary 32-kB instruction cache and 32-kB write-back data cache in each
core
• 12-MB second-level shared cache with Advanced Transfer Cache architecture
• Streaming SIMD extensions 2 (SSE2), streaming SIMD extensions 3 (SSE3),
supplemental streaming SIMD extensions 3 (SSSE3) and SSE4.1 instruction sets
• Processors are offered at 1066-MHz source-synchronous front side bus (FSB)
• Advanced power management features including Enhanced Intel SpeedStep®
Technology
• Digital thermal sensor (DTS)
• Intel® 64 architecture
• Supports Enhanced Intel® Virtualization Technology
• Supports PSI2 functionality
• Execute Disable Bit support for enhanced security
• Half ratio support (N/2) for core to bus ratio
1.1 Terminology
Term Definition
#
A “#” symbol after a signal name refers to an active low signal, indicating a
signal is in the active state when driven to a low level. For example, when
RESET# is low, a reset has been requested. Conversely, when NMI is high,
a nonmaskable interrupt has occurred. In the case of signals where the
name does not imply an active state but describes part of a binary
sequence (such as address or data), the “#” symbol implies that the signal
is inverted. For example, D[3:0] = “HLHL” refers to a hex ‘A’, and D[3:0]#
= “LHLH” also refers to a hex “A” (H= High logic level, L= Low logic level).
Front Side Bus
(FSB)
Refers to the interface between the processor and system core logic (also
known as the chipset components).
AGTL+
Advanced Gunning Transceiver Logic. Used to refer to Assisted GTL+
signaling technology on some Intel processors.
