Holoscan Sensor Bridge FPGA IP, Sensor TX (FPGA to Sensor) Support

Healthcare & Life Sciences Holoscan SDK

I am interested in using the Holoscan Sensor Bridge FPGA IP to both receive data from sensors and transmit data to sensors. Upon reading the User Guide, it says that Sensor TX is preliminary.

How mature is the Sensor TX support for the Holoscan Sensor Bridge FPGA IP? Does it have the same equivalent performance as Sensor RX? Can the User Guide provide more information on Sensor TX for the FPGA IP?

Hi Josh,

The Tx is still preliminary function to the general public. We have a reference example Tx for audio that’s very low bandwidth.

  1. RoCETransmitterOp in the examples/signal_generator.py / cpp
  2. UdpTransmitterOp in the example/linux_audio_player.py app

The Tx target performance is to achieve close to full bandwidth of the link throughput, in other words, equivalant performance as the sensor rx. The sensor TX on the FPGA is almost a dummy pass through, most work is done in the host FW and applciation SW.

Regards,

John
