5 Special Features
5.1 Hyper-Threading
Hyper-threading (officially termed Hyper-Threading Technology or HTT) is an
Intel-proprietary technology used to improve parallelization of computations
performed on PCs. Hyper-threading works by duplicating certain sections of
the processor—those that store the architectural state -- but not duplicating
the main execution resources. A hyper-threading equipped processor can appear
to be two "logical" processors to the host operating system, thus allowing
the operating system to schedule two threads or processes simultaneously.
Hyper Threading Technology support always depends on the operating system.
5.2 Onboard Hardware Monitor
The microETXexpress®-PV-XT COM has an onboard hardware monitor. The following
table lists the different sensors implemented.

Voltage 1 Module main (12V) input
voltage
A voltage divider is present on
this pin in order to be able to
read the full range of input
voltage. The reading must be
multiplied by 1.5 to have the
real value when using third party
software.
Voltage 2 Module 5V standby input
voltage
-
Voltage 3 RTC battery voltage To read this sensor properly when
using third party software, the HWM
GPIO 1 must be enabled. This feature
prevents unnecessary drainage of the
RTC battery.
