PROCESSOR TECHNOLOGIES
Intel® Hyper-Threading (Intel® HT):
This processor technology allows simultaneous
multithreading of CPU tasks to enable parallel system operations. An operating system that is
hyper-threading aware can address each core as a logical processor in order to spread out
execution tasks to improve application software efficiency and overall system speed.
Intel Virtualization Technology (Intel® VT-x):
Enabled in the SHB’s BIOS, this technology
enables multiple operating systems to run in specific processor cores thereby creating virtual
machines (VMs) on a single SHB.
Intel Virtualization Technology for Directed I/O (Intel® VT-d):
This is a sub-set of Intel VT-x and
enables I/O device assignments to specific processor cores or VMs. Intel VT-d also supports DMA
remapping, interrupt remapping and software DMA and interrupt status reporting. Intel VT-d is an
optional extension to the Intel VT-x technology.
Intel® VT-x with Extended Page Tables (EPT):
This feature is enabled in the Skylake-S
microarchitecture to supports the processor’s “real mode” or unrestricted guest feature.
Intel Trusted Execution Technology (Intel® TXT):
This processor feature works in conjunction
with the SHB’s on-board Trusted Platform Module or TPM to allow the system designer to create
multiple and separated execution environments or partitions with multiple levels of protection
and security. The TPM provides for a way to generate and store an encrypted access key for
authenticated access to sensitive applications and data. This private key never leaves the TPM, is
generally available only to authorized system administrators, and enables remote assurance of a
system’s security state.
Intel Turbo Boost Technology 2.0:
The higher performance Skylake-S processors may run above
the processors stated clock speed via a new dynamic processor speed control technology called
Intel Turbo Boost 2.0. The processor enters the boost mode when the operating system requests
the highest possible performance state as defined by the Advanced Configuration and Power
Interface or ACPI.
