26 Functional Description
3.4 Intel® Turbo Boost Technology
Intel® Turbo Boost Technology is a feature that allows the proces-
sor to opportunistically and automatically run faster than its rated
operating core and/or render clock frequency when there is suffi-
cient power headroom, and the product is within specified temper-
ature and current limits. The Intel Turbo Boost Technology feature
is designed to increase performance of both multi-threaded and
single-threaded workloads. The processor supports a Turbo mode
where the processor can use the thermal capacity associated with
package and run at power levels higher than TDP power for
short durations. This improves the system responsiveness for
short, bursty usage conditions.
Turbo Mode availability is independent of the number of active
cores; however, the Turbo Mode frequency is dynamic and depen-
dent on the instantaneous application power load, the number of
active cores, user configurable settings, operating environment,
and system design. If the power, current, or thermal limit is
reached, the processor will automatically reduce the frequency to
stay with its TDP limit.
3.5 Intel® Hyper-Threading Technology
Intel® Hyper-Threading Technology 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, Vista, and XP, and dis-
abling Hyper-Threading Technology using the BIOS for all previ-
ous versions of Windows operating systems.
3.6 Trusted Platform Module
The cPCI-6530 is optionally equipped with an Atmel AT97SC3204
Trusted Platform Module (TPM). The TPM is a secure controller
with added cryptographic functionality to provide users a secure
environment in e-commerce transactions and Internet communi-
cations.
