The PXI MultiComputing (PXImc) specification allows two or more intelligent systems to exchange data via PCI Express. Because of the excellent data transfer characteristics of PCI Express, PXImc enables PXI systems to transfer data at multigigabytes per second of practical data throughput with only a few microseconds of latency.
The NI PXIe-8383mc is the industry’s first PXImc module. It uses a x8 PCI Express 2.0 link to provide up to 2.7 GB/s of data throughput and 5 µs of one-way latency. The NI PXIe-8383mc interfaces to either the NI PXIe-8384 module or the NI PCIe-8381 board. Details on supported system configurations are available in the data sheet.
The NI-PXImc driver abstracts the low-level details of the PXImc interface and presents a simple and efficient API for transferring data. View the data sheet for more information on the NI-PXImc driver.
