TDA3: Network Throughput Performance Issue with TDA3 While Streaming

This is our custom usecase that uses 128 chirps with 256 range bins. The processing chain goes through 2 FFT + PkDetect and output 4 RDMs to Ethernet. There should be a usecase sample as such in Vision SDK. If not, please create one.

Thanks,

Khai,

If you further reduce the frame periodicity from 17ms to lesser value, do you see the dip happen in shorter intervals?

HI Stanley,

No, that 30s dip interval happens for 7 ms < framePeriodicity  < 17 ms.

Thanks,

Khai,

Could you try increasing the number (2x) of output buffers allocated for capture link? This is done in the use case set prms function.

Found it. Let me try

Void chains_radar_MetawaveRdmPeakDetect_SetPrms(chains_radar_MetawaveRdmPeakDetectObj *pObj){

      pObj->Alg_RadarProcess_fftPrm->baseClassCreate.algId  = ALGORITHM_LINK_DSP_ALG_RADAR_PROCESS;

      (pObj->Dup_fftPrm).numOutQue = 4; // Khai: Increase from 2 -> 4 per TI suggestion

      pObj->Alg_RadarProcess_pkDetectPrm->baseClassCreate.algId  = ALGORITHM_LINK_DSP_ALG_RADAR_PROCESS;

      (pObj->MergePrm).numInQue = 2;

      (pObj->NetworkTxPrm).numInQue = 1;

}

Not number of queue but number of buffers.

Stanley,

Time to resolve this issue is critical to us. Please be specific when given instruction to try. Please also try it on your end before suggesting. You told me the SetPrms function in the usecase. The only SetPrms function is the above I provided. The only output buffer in the function body is that of the output Queue. There are 4 lines of code and there isn't any Output Buffer number to be changed.
