AWR2944P: Streaming Raw ADC Data Over Ethernet

Part Number: AWR2944P
Other Parts Discussed in Thread: AWR1843BOOST, AWR2944

Tool/software:

Hi everyone,

We want to stream raw ADC data from a radar sensor, but we are looking for a cheaper and less power consuming choice rather than using DCA1000.

Formerly, we were working with AWR1843BOOST board and we were streaming the raw ADC data over UART with a very low frame rate of 1 Hz. UART bandwith did not allow higher frame (=data) rates.

Our method : We manipulate the signal processing chain, bypass everything and make the EDMA copy the raw ADC data from ADC ping pong buffers to radar data memory. Than, we streamed the raw data from memory to UART. We don't need to process the data in parallel.

Now, we need to increase the frame rate. The attached PDF file shows our analysis about data rate requirements on streaming raw ADC data.

Requirements and Constraints of Streaming Raw ADC Data Over a Serial Interface-100525-101836.pdf

Our question is that:
1000 Mbps maximum data rate of ethernet interface in awr2944 is fairly enough to stream raw ADC data.
Are there any attempts on this? Can we use ethernet in streaming raw ADC data?

Thanks for any help...

  • Hi Adem, 

    as of now, the raw ADC data streaming directly via ethernet and without DCA have not been implemented for P device, in the SDK OOB demo, a basic implementation for data streaming is available via ethernet using the TCP protocol, but that is for the object data only, not for raw ADC data, you can check it once for the reference.
