Introduction
memory and I/O transactions as well as interrupt messages pass between the
processor and chipset over the FSB.
• Storage conditions — Refers to a non-operational state. The processor may be
installed in a platform, in a tray, or loose. Processors may be sealed in packaging or
exposed to free air. Under these conditions, processor lands should not be
connected to any supply voltages, have any I/Os biased, or receive any clocks.
Upon exposure to "free air"(i.e., unsealed packaging or a device removed from
packaging material) the processor must be handled in accordance with moisture
sensitivity labeling (MSL) as indicated on the packaging material.
• 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
information.
• Intel
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 Software Developer Guide at http://
developer.intel.com/technology/64bitextensions/.
• 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
enhancements to Intel server and client platforms that can improve virtualization
solutions. Intel VT will provide a foundation for widely-deployed virtualization
solutions and enables more robust hardware assisted virtualization solutions. More

• Intel
Technology (Intel
a computer system with Intel
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.
• Platform Environment Control Interface (PECI) — A proprietary one-wire bus
interface that provides a communication channel between the processor and
chipset components to external monitoring devices.
