The following figure shows peer-to-peer pipelining topology using multiple peer-to-peer streams with an NI digitizer, an FPGA device (such as an NI FlexRIO device), and a signal generator. The digitizer contains a writer to a stream, the FPGA device contains a reader for the digitizer stream and a writer to the signal generator stream, and the a signal generator contains a reader for the FPGA device stream. The writer and reader on the FPGA device use two different device resources on the FPGA device.
You can use this type of topology in instrument control applications.
