National Instruments PXI-8840 PXI Controller

The PXI-8840 (Part Numbers: 785780-04, 785780-01, 785780-33, 785543-01, 784193-04, 784193-33, and 155186B-112L) with a Quad-Core Processor 2.6 GHz is an inserted controller for PXI frameworks. It has a maximum controller bandwidth of 132 MB/s, and an on-die L2 cache of 3 MB. It can be utilized for applications for measured instrumentation with escalated handling and data acquisition. The PXI 8840 Controller incorporates two Ethernet ports (Gigabit) 10/100/1000BASE-TX, two USB 3.0 ports, and four USB 2.0 ports, as well as an integrated hard disk, 1 RS-232 serial port, 1 ExpressCard/34 slot, and other types of peripheral I/O. The SMB connector on the NI PXI 8840 quad-core front board can associate with or from any PXI backplane trigger line. A trigger portion process is expected to keep two resources from associating with a similar trigger line, resulting in the trigger being double-driven and possibly damaging the hardware. Quad-core processors contain four cores, or computing engines, in one physical package. To expand the quantity of threads that you can process, the NI PXI 8840 consolidates Intel Hyper-Threading technology that takes every one of the four physical cores and splits the into two virtual cores, for a sum of eight virtual cores These eight virtual cores can execute eight computing tasks, which is advantageous in multitasking conditions like Windows 7.

The PXI 8840 includes multithreaded framework development environments, such as NI LabVIEW that can take full advantage of the processing cores on the NI PXI 8840 via naturally separating their tasks independent threads.

In this model, applications must be architected to make four autonomous execution threads by implementing progress strategies, including: task parallelism, data parallelism, and pipelining. Notwithstanding, Intel introduced Turbo Boost technology to provide execution benefits to a wide range of uses without requiring the application to be optimized for multicore processors.

The four-wide 3U PXI module weighs 2.77 lb. It has a recommended operating temperature range of 5 °C to 50 °C with an extended temperature option of 0 °C to 55 °C, storage temperature range of -40 °C to 65 °C also with an extended temperature option of -40 to 71 °C.
