National Instruments’ PXIe-8133 is a high-performance Intel Core i7-820QM processor-based embedded controller for use in PXI Express systems. With the 1.73 GHz base frequency, 3.06 GHz (single-core turbo) quad-core processor, and dual-channel 1333 MHz DDR3 memory, the NI PXIe-8133 is ideal for processor-intensive, modular instrumentation, and data acquisition applications.

The NI PXIe-8133 includes the quad-core Intel Core i7-820QM processor. Quad-core processors contain four cores, or computing engines, in one physical package. Previously, to fully exercise the available four cores on the NI PXIe-8133, applications had to be architected to create four independent execution threads by implementing programming strategies such as task parallelism, data parallelism, and pipelining. However, Intel introduced Turbo Boost technology to provide performance benefits for all types of applications without the application being optimized for multicore processors. It can significantly reduce test times for applications that are processor-intensive.

The NI PXIe-8133 features the Intel Core i7-820QM processor and uses advancements in PCI Express technology. This processor provides four x4 (“by four”) PCI Express Gen 2 lanes to the PXI chassis backplane. This provides up to 2 GB/s of dedicated slot bandwidth with the overall system bandwidth of up to 8 GB/s. Pairing the NI PXIe-8133 with a PXI Express chassis, such as the NI PXIe-1082 or PXIe-1075, you can simultaneously stream a larger set of I/O channels to the controller’s system RAM, allowing for the creation of larger and more complex data record and playback applications.
