Processor Performance Control
Intel
®
Atom™ processor E6xx/E6xxT series run at different voltage/frequency states (performance states), which is referred to as Enhanced
Intel
®
SpeedStep
®
technology (EIST). Operating systems that support performance control take advantage of microprocessors that use several
different performance states in order to efficiently operate the processor when it’s not being fully utilized. The operating system will determine
the necessary performance state that the processor should run at so that the optimal balance between performance and power consumption
can be achieved during runtime.
The Windows family of operating systems links its processor performance control policy to the power scheme setting. You must ensure that
your power scheme setting you choose has the ability to support Enhanced Intel
®
SpeedStep
®
technology.

Virtualization Technology
Virtualization solutions enhanced by Intel
®
VT will allow Atom™ processor E6xx/E6xxT series to run multiple operating systems and applications
in independent partitions. When using virtualization capabilities, one computer system can function as multiple “virtual” systems. With
processor and I/O enhancements to Intel
®
’s various platforms, Intel
®
Virtualization Technology can improve the performance and robustness of
today’s software-only virtual machine solutions.
Intel
®
VT is a multi-generational series of extensions to Intel
®
processor and platform architecture that provides a new hardware foundation for
virtualization, establishing a common infrastructure for all classes of Intel
®
based systems. The broad availability of Intel
®
VT makes it possible
to create entirely new applications for virtualization in servers, clients as well as embedded systems thus providing new ways to improve system
reliability, manageability, security, and real-time quality of service.
The success of any new hardware architecture is highly dependent on the system software that puts its new features to use. In the case of
virtualization technology, that support comes from the virtual machine monitor (VMM), a layer of software that controls the underlying physical
platform resources sharing them between multiple “guest” operating systems. Intel
®
VT is already incorporated into most commercial and
open-source VMMs including those from VMware, Microsoft, XenSource, Parallels, Virtual Iron, Jaluna and TenAsys.

Note
congatec does not offer virtual machine monitor (VMM) software. All VMM software support questions and queries should be directed to the
VMM software vendor and not congatec technical support.
