2.0 Technologies
This chapter provides a high-level description of Intel technologies implemented in the
processor.
The implementation of the features may vary between the processor SKUs.
Details on the different technologies of Intel processors and other relevant external
notes are located at the Intel technology web site: http://www.intel.com/technology/
NOTE
The last section of this chapter is dedicated to deprecated technologies. These
technologies are not supported in this processor but were supported in previous
generations.
Platform Environmental Control Interface
Platform Environmental Control Interface (PECI) is an Intel proprietary interface that
provides a communication channel between Intel processors and external components
such as Super IO (SIO) and Embedded Controllers (EC) to provide processor
temperature, Turbo, Assured Power (cTDP), and Memory Throttling Control
mechanisms and many other services. PECI is used for platform thermal management
and real-time control and configuration of processor features and performance.
NOTE
• PECI over eSPI is supported.
PECI Bus Architecture
The PECI architecture is based on a wired-OR bus that the clients (as processor PECI)
can pull up (with the strong drive).
The idle state on the bus is ‘0’ (logical low) and near zero (Logical voltage level).
NOTE
PECI supported frequency range is 3.2 kHz - 1 MHz.
The following figures demonstrate PECI design and connectivity:
• PECI Host-Clients Connection: While the host/originator can be third party PECI
host and one of the PECI client is a processor PECI device.
• PECI EC Connection.

Virtualization Technology
Intel
®
Virtualization Technology (Intel
®
VT) makes a single system appear as multiple
independent systems to software. This allows multiple, independent operating systems
to run simultaneously on a single system. Intel
®
VT comprises technology components
to support Virtualization of platforms based on Intel
®
architecture microprocessors
and chipsets.
Intel
®
Virtualization Technology (Intel
®
VT) Intel
®
64 and Intel
®
Architecture (Intel
®
VT-x) added hardware support in the processor to improve the Virtualization
performance and robustness. Intel
®
Virtualization Technology for Directed I/O (Intel
®
VT-d) extends Intel
®
VT-x by adding hardware assisted support to improve I/O device
Virtualization performance.
Intel
®
VT-x specifications and functional descriptions are included in the Intel
®
64
Architectures Software Developer’s Manual, Volume 3. Available at:
http://www.intel.com/products/processor/manuals
The Intel
®
VT-d specification and other VT documents can be referenced at:
