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.
