Overview
The National Instruments PXI-8105 is a high-performance Intel Core Duo
T2500-based embedded controller for use in PXI and CompactPCI systems.
With its 2.0 GHz dual-core processor and dual-channel 667 MHz DDR2
memory, the NI PXI-8105 is ideal for applications requiring intensive
analysis or system development. A PXI-8105 embedded controller in a
PXI chassis offers a compact, high-performance PC platform for modular
instrumentation and data acquisition applications.

Dual-Core Processor
The PXI-8105 includes an Intel Core Duo T2500 dual-core processor.
Dual-core processors have two cores, or computing engines, located in
one physical package. With two cores, dual-core processors can
simultaneously execute two computing tasks. This feature is

advantageous in multitasking environments, such as Windows XP, where
multiple applications can run simultaneously. Two applications, such as
NI LabVIEW and Microsoft Excel, can each execute on a separate core
at the same time, which improves overall performance. Applications that
use multithreading can also take advantage of dual-core processors.
Multithreaded applications separate their tasks into individual threads.
A dual-core processor can simultaneously execute two of these threads.
