[RadarSDK] Break point for Radar processing data layout

Koichi Saito
Intellectual 2525 points

Hi Expert,

Radar proceesing data flow is described in "Appendix D: Radar Processing Data Flow" in EVE_Applets_UserGuide.pdf.

Each Data layout of Radar processing is shown in following Figures.

   Figure 3: Output of ARxx sensor
   Figure 4: Output of Range FFT/Input to Doppler FFT
   Figure 5: Output of Doppler FFT
   Figure 6: Antenna Data out after Peak Detection
   Figure 7: CFAR CA Detection

My customer wants to confirm each data above in DDR when running Radar SDK usecase with CCS.

Can you please tell me the line number & file name to be set as break point and buffer name (structs and variables) to look at each DDR data in CCS memory window ?

Data Layout Buffer name Break point (Line number) Filename
ARxx sensor output
Range-FFT output
Doppler-FFT output
Peak Detection output
CFAR CA output

RadarSDK : Processor SDK Radar 3.6
Usecase : "3: Radar (Single AR1243) Capture + Radar Object Detect (EVE1) + Display (TDA3xx Only)"

Best regards,
Saito

    Hi, 

    I am forwarding this question to a team member in the Automotive Processors group. 

    Thank you,

    ARxx sensor output : 

    Function: AlgorithmFxn_RadarFftProcess

    Address: inBufAddr

    File: vision_sdk\apps\src\rtos\radar\src\alg_plugins\alg_fxns\radarfft2\radarFft2.c

    Range-FFT output:

    Function: AlgorithmFxn_RadarFftProcess

    Address: pObj->intermediateBuf

    File: vision_sdk\apps\src\rtos\radar\src\alg_plugins\alg_fxns\radarfft2\radarFft2.c

    Doppler-FFT output:

    Function: AlgorithmFxn_RadarFftProcess

    Address: outBufAddr and (AlgorithmFxn_RadarFftBuffDescriptor *) metaDataBuffAddr

    File: vision_sdk\apps\src\rtos\radar\src\alg_plugins\alg_fxns\radarfft2\radarFft2.c

    Peak Detection output and CFAR CA output are the same:

    Function: AlgorithmFxn_RadarPkDetectProcess

    File: vision_sdk\apps\src\rtos\radar\src\alg_plugins\alg_fxns\radarpeakdetect\radarPkDetect.c

    Address: outBuf

    Beam form Output:

    File: vision_sdk\apps\src\rtos\radar\src\alg_plugins\alg_fxns\radarbeamform\radarBeamForm.c

    Function: AlgorithmFxn_RadarBeamFormProcess

    Address: outBuf

    Thanks and Regards,

    Piyali
