PXI Express Features

Benefits of PXI Express

The PXI (PCI eXtensions for Instrumentation) industry standard, an open specification

governed by the PXI Systems Alliance (PXISA), has quickly gained adoption and grown in

prevalence in test, measurement, and control systems since its release in 1998. One of the key

elements driving the rapid adoption of PXI is its use of PCI in the communication backplane.

As the commercial PC industry has improved the available bus bandwidth by evolving PCI to

PCI Express, PXI is now able to meet even more application needs by integrating PCI Express

into the PXI standard. By taking advantage of PCI Express technology in the backplane, PXI

Express increases the available PXI bandwidth from up to 132 MB/s to up to 8 GB/s for a

more than 60x improvement in bandwidth.

PXI Express maximizes both hardware and software compatibility with PXI modules. PXI

Express hybrid slots deliver both PCI and PCI Express signaling to accept devices that use

PXI communication and triggering or the newer PXI Express standard. Software compatibility

is maintained because PCI Express uses the same OS and driver model as PCI, resulting in

complete software compatibility among PCI-based systems, for example PXI, and PCI

Express-based systems such as PXI Express.

PXI Express, like PXI, leverages from the CompactPCI specification to define a rugged,

modular form factor that offers superior mechanical integrity and easy installation and removal

of hardware components. PXI Express products offer higher and more carefully defined levels

of environmental performance required by the shock, vibration, temperature, and humidity

extremes of industrial environments. Mandatory environmental testing and active cooling is

added to the CompactPCI mechanical specification to ease system integration and ensure

multivendor interoperability.

The demanding timing and synchronization requirements of instrumentation systems are met

by the integrated features of PXI Express. Not only are the trigger bus, 10 MHz system

reference clock, and star trigger bus available in PXI retained by PXI Express, but new timing

and synchronization features that include a 100 MHz differential system reference clock for

the synchronization of multiple modules and three differential star trigger buses for the

distribution of precise clock and trigger signals have been added. Differential timing and

synchronization signals provide PXI Express systems with increased noise immunity and the

ability to transmit clock signals at higher frequencies.

NI PXIe-8840 Quad-Core

base frequency for short durations, while other cores are idle. Enabling Turbo Boost also

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.

NI PXIe-8840 Quad-Core User Manual | © National Instruments | 9

•Hardware Prefetcher—This setting enables or disables CPU cache hardware
