Supported PXI Express FPGA Module Functionality

  • Arbitration — This device supports arbitration to determine which object can access the resource if multiple objects request access at the same time. Configure the arbitration settings for the channels of this device in the FPGA I/O Properties dialog box for the FPGA I/O item you are using.
  • FPGA Base Clocks — This device supports FPGA base clocks. For more information about the available base clock resources, refer to the PXIe-796x Base Clocks or PXIe-797x Base Clocks topic depending on your module.
  • Single-Cycle Timed Loop — This device supports the single-cycle Timed Loop for the implementation of multiple clock domains in an FPGA VI.
  • Peer-to-Peer Streaming — This device supports peer-to-peer data streaming. Use LabVIEW FPGA to configure your FlexRIO device to set up a peer-to-peer streaming session.
  • FlexRIO Peer-to-Peer Resource Availability — FlexRIO PXI Express devices support both Peer-to-Peer Reader and Peer-to-Peer Writer streams. You can configure a total of 16 streams. The following table lists the stream types available for FlexRIO PXI Express devices.
FIFO Type Description
DMA input Reads data into the FIFO from the VI.
DMA output Writes data from the FIFO into the VI.
P2P Writer Writes data to the peer-to-peer reader device.
P2P Reader Reads data from the peer-to-peer writer device.
