NPU documentation and tools

When will this info and tool be available?
My main usage of VIM3 is for deep learning.

@kaishi It will take some time. Please wait patiently.We are dealing with it

Any idea when this will be available?


Hi @kaishi
Actually, as the Amlogic A311D use the Verisilicon NPU IP, and they require each clients to sign the NDA with Verisilicon to get a KEY ID for each project first, then they will release the toolkit and documentations.

We still try to simply the process for VIM3 users, but it might take some time, we will update more here in the next few days.


Any news on this topic? Also who will be providing the integration with TensorFlow? Does this come with the Verisilicon Toolkit or will you build an extension that allows TensorFlow to make use of the NPU through Verisilicon’s toolkit?

Rockchip 3399pro also uses Verisilicon NPU IP,.
Is A311D NPU performance better than RK3399Pro?
Toybrick has released conversion tools library, rknn for ubuntu. Can this tool be used for A311D’s ubuntu system?


We also have the model convert tool, we’ll release the tool when the licence issue is resolved.

I was wondering if the architecture of the A311D is compatible in some way with Qualcomm’s Hexagon. If it is we could use Xiaomi Mace framework for AI, it has excellent performance even compared to tflite.
