These extensions enhance two areas:
• The launching of the Measured Launched Environment (MLE)
• The protection of the MLE from potential corruption
• The protection of the MLE from potential corruption
The enhanced platform provides these launch and control interfaces using Safer Mode
Extensions (SMX).
Extensions (SMX).
The SMX interface includes the following functions:
• Measured/Verified launch of the MLE
• Mechanisms to ensure the above measurement is protected and stored in a secure
• Mechanisms to ensure the above measurement is protected and stored in a secure
location
• Protection mechanisms that allow the MLE to control attempts to modify itself

Hyper-Threading Technology
The processor supports Intel

Hyper-Threading Technology (Intel

HT Technology),
that allows an execution core to function as two logical processors. While some
execution resources (such as caches, execution units, and buses) are shared, each
logical processor has its own architectural state with its own set of general-purpose
registers and control registers. This feature must be enabled using the BIOS and
requires operating system support.

Intel recommends enabling Hyper-Threading Technology with Microsoft Windows 7*,
Microsoft Windows Vista*, Microsoft Windows* XP Professional/Windows* XP Home,
and disabling Hyper-Threading Technology using the BIOS for all previous versions of
Windows operating systems. For more information on Hyper-Threading Technology, see

Turbo Boost Technology
Intel
®
Turbo Boost Technology is a feature that allows the processor core to
opportunistically and automatically run faster than its rated operating frequency/render
clock if it is operating below power, temperature, and current limits. The Intel Turbo
Boost Technology feature is designed to increase performance of both multi-threaded
and single-threaded workloads. Maximum frequency is dependant on the SKU and
number of active cores. No special hardware support is necessary for Intel Turbo Boost
Technology. BIOS and the OS can enable or disable Intel Turbo Boost Technology.
Compared with previous generation products, Intel Turbo Boost Technology will
increase the ratio of application power to TDP. Thus, thermal solutions and platform
cooling that are designed to less than thermal design guidance might experience
thermal and performance issues since more applications will tend to run at the
maximum power limit for significant periods of time.
