AWR1843BOOST: AWR1843. HWA Module and BPM removal operation

Part Number: AWR1843BOOST

When configuring the HWA (mode: HWA_ACCELMODE_FFT) using the BPM removal feature.
The bpmPattern / bpmRate / bpmPhase / bpmEnable parameters do not affect the result of the HWA.
Was the "BPM Removal" mode in mmWave SDK 3 checked? If so, how can I get an example of the correct configuration?

    Hi,

    We have to check with the design team how this feature was validated.

    We should be able to get back to you in a few days.

    thank you

    Hi,

    I have checked with the SDK team and there is no example available.

    Could you provide the Paramset configuration for this operation?

    Thank you

    Hello! Thanks for the answer.


    For the BPM test, I used the mmwave_sdk_03_04_00_03\packages\ti\datapath\dpc\dpu\dopplerproc\src\dopplerprochwa.c module
    with the following differences:
    in the function DPU_DopplerProcHWA_configHwa () set hwaParamCfg [paramsetIdx] .source.bpmEnable = 1;
    and in the DPU_DopplerProcHWA_process () function, before calling the HWA_configCommon () function, I added:
         hwaCommonConfig.fftConfig.bpmPattern [0] = 0x11111111;
         hwaCommonConfig.fftConfig.bpmPattern [1] = 0x22222222;
         hwaCommonConfig.fftConfig.bpmRate = 1;

    The HWA documentation provides an alternative method for implementing BPM through window overlay. I decided to use this method. The result suits me.

    thank you.
