The NI PCI-5640R is a 32-bit PCI bus device with bus mastering capabilities. The NI-STC2 ASIC provides the PCI bus interface on the NI PCI-5640R.
One of the advantages of the National Instruments DAQ-STC2 ASIC is its scatter-gather direct memory access (DMA) capabilities, which are used by LabVIEW to efficiently transfer data between the host PC and the NI PCI-5640R FPGA.
