NI PXIe-8383mc (153100x-02L) Block Diagram
The PXImc logic block consists of a non-transparent bridge and all the associated circuitry
necessary to work with clock references from both the Primary System Host and the PXImc
Device’s own sub-system. The non-transparent bridge (NTB) isolates the processor and
resources in the Primary System Host from those in the sub-system. The NTB is recognized as
a PCI Express system endpoint to each of the systems. As a result, devices and other PCI
resources on either side of the NTB are not visible to each other. Communication between the
