TDA2EXEVM: PROCESSOR_SDK_VISION_03_05_00_00 usecase issue

Hi,

The issue was solved.

The performance dropping is caused by the reason that the TIDL model files is generated by the old version.

It seems that the OD usecase in SDK 0305 is not compatible with the old version tidl TIDL.01.01.01.00.

Thank you.

Hi,

Can you please increase the value of SYNC_THRESHOLD macro in \vision_sdk\apps\src\rtos\usecases\tidl_OD\chains_tidlOD.c file
Adjust it to proper value where you dont see any frame drop by sync link.

Anuj

Hi Anuj,

Thank you for your response.
I try to increase the value from 600 to 800 ,1000 and also 2000.
But after some frames, it still have some frame drop.
Should i try to increase it to larger value?
Btw, the old version SDK-0304 OD usecase did not have this issue.
Use the default value 600 and it works well.

Hi,

Have you created your model using the new tidl release?
And that works with VSDK v3.4 but not with 3.5?

Hi Anuj,

I have two model ,the one is faster(4 EVE 30 FPS) the other one is slower(4EVE 25FPS)

I observe the below cases:

1. Faster model import using old version TIDL .
with new usecase , frame drop.
2. Faster model import using new version TIDL.
with new usecase , no frame drop.
3. Slower model import using new version TIDL.
with new usecase, frame drop.
4. both models on the old usecase ,no frame drop

I have no ideal about this issue.
Could you please tell me the above usecase files is proper or not?

Hi Eric Lai,

From old version of TIDL(01.01.01.00) to this new version of TIDL(01.01.02.00) nothing much changed, so we are not expecting any change in the behaviour between these two releases.

Can you double check your observations once?

If you still see these differences, can you profile your both old and new models on TIDL test bench and check are there any differences in the performance on standalone also?

Thanks,
Praveen

Hi Praveen,

Thank you for your response.

I am not sure about the issue is caused from TIDL or the usecase.

But I guess it is more possible that it was caused by the usecase i built.

Here are some other observation.

I built other three usecase for OD , so totally I have four use-case:

1. OD using 4EVE (video input)

2. OD using 4EVE (camera input)

3. OD using 3EVE (video input)

4. OD using 3EVE (camera input)

And for the faster model i mentioned above.

usecase 1 and 2 :  okay , no frame drop

usecase 3 and 4:  frame drop

For the slower model:

usecase 1 : no frame drop.

usecase 2 3 4 : frame drop.

It seems that the use-case i built have some problem.

The 4eve camera in usecase log and files are on the top of this thread.

And here i put the 3eve camera in usecase log and files.

Could you please help me to check if my files are proper or not?

Thank you so much.

Hi,

Any updates?
I am not sure if my usecase setting is wrong or correct.
Would you please give me some suggestion.

Hi,

1st thing please dont use camera input.
Use the sd card input file.

If with the same model using 4 eve there is no frame drop and with 3 eves there is frame drop then the issue could be with usecase.
But as you are using 3 eve so you have to reduce the FPS, so can you try with 20 FPS with opp-high MLO

Anuj

 Hi Anuj,

Thank you for your response.

I lower down the fps of 3EVE video input use-case.

And I do not observe any frame drop now.

It's great. Thank you.

But for the camera input usecase, it's the same.

Would you please help me to check the 3EVE camera input use-case files?
