Part Number: TDA2EXEVM

Hello,

I had model evaluation question .

The below link :

e2e.ti.com/support/arm/automotive_processors/f/1021/t/672167

I use the CCS to run the tidl testbech on the EVE core.

And got the below result:

i didn't see any MAC evaluation on the console.

I want to know how the get the real MAC based on the EVE.

Thank you in advance.

Sincerely,

Eric Lai

The TSC cycles printed here is EVE cycles used for processing the entire network. We can run the dense and sparse network to understand the importance of sparse convolution on EVE. We recommend to run segmentation example network from caffe jacinto model for understanding performance with sparsity.

Thanks and regards

Hello Kumar,

Thank you for your response.
Okay ,I will try the segmentation model to see the difference.
Can you tell me the relationship between the TSC cycles and FPS?
Because i have a big model but with high sparsity, i want to know it's okay or not to execute fast enough on EVE?
Can you give me some information or number of MACS or TSC if i want to put a model on EVE?

Sincerely ,
Eric Lai

Total EVE core clock / TSC cycles to process one inference would give you FPS.
For example, if EVE is clocked at 650MHz and one inference is taking 100 Mega cycles then we would reach 6.5 FPS with one EVE. If the part you are using has 4 EVEs then it would be 6.5 *4 = ~25 FPS

Please Refer below thread on more information
