DNNDK network output physical address?

Hi,

I asked this question before and didn't get a satisfying answer. I am wondering how to get the physical address of DNNDK output tensor. The one address given by dpuGetOutputTensorAddress is only the virtual address. I want to know the physical address of the output tensor in the DRAM. 

xilinx_ai_sdk output_tensor has a field phy_addr which gives the physical addr. What is the equivalent in DNNDK?

HI @baharlab ,

 

Have you tried the common third party solution like:

translate virtual addess to physical.

I have done some test on MPSoC before but not a DPU design.

Best Regards,
Jason
