PXI Features
Benefits of PXI
The PXI (PCI eXtensions for Instrumentation) industry standard, an open specification
governed by the PXI Systems Alliance (PXISA), defines a compact modular PC platform for
test, measurement, and control systems. Because PXI leverages the PCI bus, PXI users receive
all the benefits of PCI within an architecture that supports mechanical, electrical, and software
features tailored to industrial instrumentation, data acquisition, industrial automation, and
control applications.
Well-suited for industrial applications, PXI leverages from the CompactPCI specification,
which defines a rugged form factor for PCI that offers superior mechanical integrity and easy
installation and removal of hardware components. PXI products offer higher and more
carefully defined levels of environmental performance required by the vibration, shock,
temperature, and humidity extremes of industrial environments. PXI adds mandatory
environmental testing and active cooling to the CompactPCI mechanical specification to ease
system integration and ensure multivendor interoperability.
Additionally, PXI meets the more specific needs of instrumentation users by adding an
integrated trigger bus and reference clock for multiple-board synchronization, a star trigger
bus for very precise timing, and local buses for side-band communication between adjacent
peripherals.

control in Linux has been improved by the NI-VISA driver for Linux, and NI modular
instruments are partially supported. For more information, visit ni.com/linux.
Configuration
BIOS Setup Utility
You can change the NI PXI-8840 configuration settings in the BIOS setup program. The BIOS
is the low-level interface between the hardware and operating system software that configures
and tests your hardware when you boot the system. The BIOS setup program includes menus
for configuring settings and enabling NI PXI-8840 controller features.
Most users do not need to use the BIOS setup program, as the NI PXI-8840 controller ships
with default settings that work well for most configurations.
Caution Changing BIOS settings may lead to incorrect controller behavior and
possibly an unbootable controller. If this happens, follow the instructions for
restoring default settings in the System CMOS section. In general, do not change a
setting unless you are absolutely certain what it does.

can increase application jitter, so be careful when enabling this setting on a Real Time
system. To achieve maximum possible Turbo Boost frequencies, also enable the C-States
setting. When the BIOS is configured to boot LabVIEW Real-Time, Turbo Boost is
disabled automatically. To manually enable Turbo Boost performance when in LabVIEW
Real-Time mode, refer to the LabVIEW RT Configuration Overrides Submenu.
•C-States—This setting enables or disables CPU power management. The default value is
Enabled. Enabling C-States allows the processor to put idle CPU cores to sleep, allowing
active cores to run at higher than base frequencies when Turbo Boost is enabled. Enabling
C-States can increase application jitter, so be careful when enabling this setting on a Real
Time system. When the BIOS is configured to boot LabVIEW Real-Time, C-States are
disabled automatically. To manually enable C-States when in LabVIEW Real-Time mode,
refer to the LabVIEW RT Configuration Overrides Submenu.
•Hardware Prefetcher—This setting enables or disables CPU cache hardware
prefetching. The default value is Disabled when booting LabVIEW Real-Time and
Enabled when booting other OSs. Enabling hardware prefetching can increase system
performance for some applications, but can cause control algorithms to behave less
deterministically.
•Adjacent Cache Line Prefetch—This setting enables or disables prefetching of adjacent
cache lines from memory to the CPU cache. The default value is Disabled when booting
LabVIEW Real-Time and Enabled when booting other OSs. Enabling adjacent cache
