Original question:

Compiler/TDA3XEVM: UseCase Link

RTOS: Error while adding Alg_ImagePreProcess link

Tool/software: TI-RTOS

Hello,

We are trying to run tidl_OD usecase using TDA2x board. Input is capture from HDMI RX 1920x1080 @ 60fps - VIP, YUV422.

Usecase:

UseCase: chains_capture_tidl_OD

Capture ->Alg_ImagePreProcess(EVE1) -> VPE -> Dup

Dup -> Merge

Dup -> Alg_tidlpreproc (A15)

Alg_tidlpreproc (A15) -> Alg_tidl_Eve1 (EVE1)
Alg_tidlpreproc (A15) -> Alg_tidl_Eve2 (EVE2)
Alg_tidlpreproc (A15) -> Alg_tidl_Eve3 (EVE3)
Alg_tidlpreproc (A15) -> Alg_tidl_Eve4 (EVE4)

Alg_tidl_Eve1 (EVE1) -> Merge_OD (DSP1)
Alg_tidl_Eve2 (EVE2) -> Merge_OD (DSP1)
Alg_tidl_Eve3 (EVE3) -> Merge_OD (DSP1)
Alg_tidl_Eve4 (EVE4) -> Merge_OD (DSP1)
Merge_OD (DSP1) -> Alg_tidl_Dsp (DSP1) -> Merge

Merge -> Sync -> Alg_ObjectDraw -> Display_Video

GrpxSrc -> Display

When I add Alg_ImagePreProcess(EVE1) , I am facing below error:

    Hi,

    Which usecase are you trying to run?
    Can you share the exact Path for that?

    Hello Anuj,

    As per mentioned above, I am trying to run tidl_OD usecase. In that base usecase , I have added Capture from HDMI and Alg_ImagePreProcess link on input.

    Path for base usecase : C:\PROCESSOR_SDK_VISION_03_03_00_00\vision_sdk\apps\src\rtos\usecases\tidl_OD

    Hi,

    The assert is coming while memory allocation from local heap.
    As your Alg_ImagePreProcess is also running on EVE1 so when TIDL tries to allocate memory , it does not have that much of free space.
    Increase the data memory of EVE1 core.
    Note that EVE memories should be 16 MB aligned.

    Regards,
    Anuj

    Hello Anuj,

    Thanks for the help. As you say :

    Increase the data memory of EVE1 core.

    >>  As I am new to this, I need to explore the memory segment concept. For that I am referring below document:

    C:\PROCESSOR_SDK_VISION_03_03_00_00\vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_MemoryMap.pdf

    Instead of this Do you have any other reference document? Please suggest.

    Beside this I tried one approach like, I changed the usecase as below:

    UseCase: chains_capture_tidl_OD

    Capture ->Alg_ImagePreProcess(EVE1) -> VPE -> Dup

    Dup -> Merge

    Dup -> Alg_tidlpreproc (A15)

    Alg_tidlpreproc (A15) -> Alg_tidl_Eve2 (EVE2)

    Alg_tidlpreproc (A15) -> Alg_tidl_Eve3 (EVE3)

    Alg_tidlpreproc (A15) -> Alg_tidl_Eve4 (EVE4)

    Alg_tidl_Eve2 (EVE2) -> Merge_OD (DSP1)

    Alg_tidl_Eve3 (EVE3) -> Merge_OD (DSP1)

    Alg_tidl_Eve4 (EVE4) -> Merge_OD (DSP1)

    Merge_OD (DSP1) -> Alg_tidl_Dsp (DSP1) -> Merge

    Merge -> Sync -> Alg_ObjectDraw -> Display_Video

    GrpxSrc -> Display

    Removed the Alg_tidl_Eve1 (EVE1) and changed the .c file accordingly.

    It's running without error, but showing output like this:

    Is this approach is right? Please guide me to resolve this.

    Please find attached statistics for your reference.

    Hi,

    TIDL_OD is not tested using capture link.
    Its been tested on file read.
    You need to train your model for the input.

    Hello Anuj,

    I have modified tidl_OD use case for taking input from HDMI and it's working, but when I have added Alg_ImagePreProcess link after capture it's displaying output like previously attached image.

    Hi,

    Why you want to use Alg_ImagePreProcess link.
    The kink is used when you want use ti developed object detection algorithm not with TIDL.

    Hello Anuj,

    I want to try and observe effect of pre processing on TIDL inference. I think pre processing may improve the detection results that's why I need to try that.

    Hi,

    The issue is coming due to format of Alg_ImagePreProcess and tidl is not matching.
    And the both of the link has been tesed in a single usecase flow as both of them are used with 2 separate algos.

    Still if you want to check you can coneect with CCS and debug where the format is going wrong.
