Linux/TDA2EXEVM: TIDL_OD on linux too slow

Taekmin Lee
Expert 1445 points

Part Number: TDA2EXEVM

Tool/software: Linux

Hi.

I'm working on porting TIDL_OD Usecase to Linux+BIOS using TDA2X EVM. (with Vision SDK 3.06)

I've finished porting, but the result display is too slow.

In original(BIOS) usecase, the result is about 20FPS but my porting(Linux+BIOS) usecase result is about 2FPS.

In the porting work, the link changed NullSrc to IPU->A15 and TIDL_Preprocessing to A15->IPU.

I checked using "System Statistics" to find out the cause, and a lot of frames were being droped from the VPE.(25 frames out of 30 frames dropped.)

TIDL_Preprocessing has been changed from A15 to IPU, possibly due to the IPU's slower frequency than A15.

So my question is three.

1. Checking the document makes it seem possible to set up an OPP(OPerating Point).
    How can I set the IPU to OPP High in Linux Usecase?

2. If I use to TIDL_Preprocessing on A15 core in Linux Usecase, do I need to port the algorithm? Or Something?
    I tried it before but failed. https://e2e.ti.com/support/processors/f/791/t/801015

3. While looking the community, I saw that TIDL Linux Usecase was included in the next release of the Vision SDK.
    Is that true? If true, when is Vision SDK's next release?

Regrds,

    To compare the logs...
    The problem with too many frame drop on VPE seems to be TIDL_Preprocessing.

    Hi,

    TIDL_OD is not been tested on Linux.

    So we can not promise any desired performance with this.

    Still you can share the complete log and we can have a look.

    Hi, Anuj.

    I attached Linux TIDL_OD Usecase log file.

    And, please answer the 3 questions of the previous post.

    I'm resolved this issue.

    I'm ported 'ALG_TIDLpreprocessing' on DSP.

    Regrads,
