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.
