TDA2EXEVM: Question about TDIL OD fps and input resolution of a model

Hi,

For my understanding, the larger input image size of a model, the lower fps on TDA2.

When I test with 3 different input image size model, 768x320, 1080x635 and 1280x720, I got 22 and 5.47 and 9.65, respectively.

Is this reasonable?

I'm wounder what will make this happen.

Thank you,
Gary

Hi Gary,

you can press 'p' when running the usecase to get statistics of the various links (including TIDL link) and see their input fps, output fps, processing time, etc.

Can you try this and see if you can find what cause such behaviour?

Yordan

Hi Yordan,

Here are the statistics for two different resolution models.

1280x720.txt

1080x636.txt

As I can see, 1080x636 model take more time in TIDL part.

I use the same model but different resolution to train.

If all settings are the same, is there any reason make this happen?

Thank you,
Gary

Hi Gary,

>> As I can see, 1080x636 model take more time in TIDL part.

Yes, this expected because this resolution is not suitable for SIMD optimization, as TIDL operates on blocks of 32x32, so you see some degradation compare to other resolutions. It is recommend to use resolutions that are multiples of 32 to get better fps.

Thanks,

Praveen
