Datasheet

Introduction

• Functional operation — Refers to normal operating conditions in which all

processor specifications, including DC, AC, system bus, signal quality, mechanical

and thermal are satisfied.

• Execute Disable Bit — Allows memory to be marked as executable or non-

executable, when combined with a supporting operating system. If code attempts

to run in non-executable memory the processor raises an error to the operating

system. This feature can prevent some classes of viruses or worms that exploit

buffer over run vulnerabilities and can thus help improve the overall security of the

system. See the Intel® Architecture Software Developer's Manual for more detailed

information.

• Intel® 64 Architecture — An enhancement to Intel's IA-32 architecture, allowing

the processor to execute operating systems and applications written to take

advantage of Intel 64 architecture. Further details on Intel 64 architecture and

programming model can be found in the Intel® Extended Memory 64 Technology

Software Developer Guide at http://www.intel.com/technology/intel64/index.htm.

• Enhanced Intel SpeedStep® Technology — Enhanced Intel Speedstep®

technology allows trade-offs to be made between performance and power

consumptions, based on processor utilization. This may lower average power

consumption (in conjunction with OS support).

• Intel® Virtualization Technology (Intel VT) — Intel Virtualization Technology

provides silicon-based functionality that works together with compatible Virtual

Machine Monitor (VMM) software to improve upon software-only solutions. Because

this virtualization hardware provides a new architecture upon which the operating

system can run directly, it removes the need for binary translation. Thus, it helps

eliminate associated performance overhead and vastly simplifies the design of the

VMM, in turn allowing VMMs to be written to common standards and to be more

robust. See the Intel® Virtualization Technology Specification for the IA-32 Intel®

Architecture for more details.

• Intel® Trusted Execution Technology (Intel® TXT)— Intel® Trusted Execution

Technology (Intel® TXT) is a security technology under development by Intel and

requires for operation a computer system with Intel® Virtualization Technology, a

Intel Trusted Execution Technology-enabled Intel processor, chipset, BIOS,

Authenticated Code Modules, and an Intel or other Intel Trusted Execution

Technology compatible measured virtual machine monitor. In addition, Intel Trusted

Execution Technology requires the system to contain a TPMv1.2 as defined by the

Trusted Computing Group and specific software for some uses.
