This chapter provides overview information for PXI Express and the NI PXIe-8880 embedded
controller.
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 48 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.
The NI PXIe-8880 PXI Express/CompactPCI Express embedded computer is a high bandwidth
PXI Express/CompactPCI Express-compatible system controller. The NI PXIe-8880 controller
integrates standard I/O features in a single unit by using state-of-the-art packaging. Combining
an NI PXIe-8880 embedded controller with a PXI Express-compatible chassis, such as the
NI PXIe-1085, results in a fully PC-compatible computer in a compact, rugged package.
The standard I/O on each module includes one DisplayPort 1.2 video port, four high-speed
USB 2.0 ports, two high-speed USB 3.0 ports, a PCI-based GPIB controller, two Gigabit
Ethernet connectors, a reset button, and PXI Express triggers.
®
The NI PXIe-8880 has an eight-core Intel
1866 MHz memory, all the standard I/O, and an integrated sold-state drive.

•SATA Controller(s)—This setting specifies whether or not the onboard SATA controller
is enabled or disabled. The default value is Enabled.
–SATA Mode Selection—This setting determines whether AHCI mode is enabled or
disabled for the SATA port. Some operating systems, such as Windows 2000, do not
support AHCI mode. You can use this setting to disable AHCI mode and enable IDE
mode so that non-compatible OSes function correctly. The default value is AHCI.
•Internal Drive (SATA)—This item displays the onboard SATA drive detected in the
system.
CPU Configuration Submenu
Use this submenu to apply alternate settings to the CPU. Normally, you do not need to modify
these settings, as the factory default settings provide the most compatible and optimal
configuration possible.
•Hyper-Threading—This setting enables or disables Intel Hyper-Threading technology.
The default value is Enabled. Enabling Hyper-Threading increases performance for some
applications by adding virtual CPU cores. Hyper-Threading can increase application jitter,
so care should be taken when enabling this setting on a Real Time system. When the BIOS
is configured to boot LabVIEW Real-Time, Hyper-Threading will be automatically
disabled.
•Enabled CPU Cores—This setting selects the number of active CPU cores for the
processor. Valid values are All, 7, 6, 5, 4, 3, 2, or 1. The default value is All.
•Turbo Boost—This setting enables or disables Intel Turbo Boost technology. The default
value is Enabled. Enabling Turbo Boost allows CPU cores to run at higher than their base
frequency for short durations, while other cores are idle. Enabling Turbo Boost can also
increase application jitter, so care should be taken when enabling this setting on a Real Time
system. To achieve maximum possible Turbo Boost frequencies, also enable the C-States
setting.
•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 care should be taken when enabling this setting
on a Real Time system. When the BIOS is configured to boot LabVIEW Real-Time,
C-States will be automatically disabled.
•Hardware Prefetcher—This setting enables or disables CPU cache hardware prefetching.
The default value is Enabled. Enabling hardware prefetching can increase system
performance for some applications, but can cause control algorithms to behave less
deterministically.
•Adjacent Cache Prefetcher—This setting enables or disables prefetching of adjacent
cache lines from memory to the CPU cache. The default value is Enabled. Enabling
adjacent cache line prefetching can increase system performance for some applications, but
can cause control algorithms to behave less deterministically.
•Data Cache Unit (DCU) Prefetcher—This setting enables or disables prefetching of the
next cache line when accessing very recently used data in an ascending fashion. The default
