How to access APU in Mediatek chipsets

[adarsh_a]

I am working on Mediatek mobile phones : Mediatek Dimesnity 9000, Dimensity 920, Dimensity 1200.
I can access the APU on Mediatek 9000 using the AI benchmark app, but cannot do so on Dimenity 920 , mediatek website says that it has a AI processor , hopefully it is a APU.
Apart from the AI benchmark app, how do I access the APU using Neuron delegate?

I am getting an error : Neuron Adaptor exists : 0 , when I invoke the tflite Neuron delegate.

but cannot do so on Dimenity 920

Try force enabling the Neuron delegate in the acceleration settings by pressing > 3 times on this option. The latest Neuron build should generally be compatible with Dimensity 920-based phones running Android T.

Apart from the AI benchmark app, how do I access the APU using Neuron delegate?

It should be also accessible through Android NNAPI.

Hi Andrey,

Thanks for the response, I forced enabled the Neuron delegate. I am able to benchmark the pre existing models on the app like : SRGAN, PUNET, XLSR, VideoSR 4k on the neuron delegate. But the option to check the MediaTek Neuron for running custom model is not enabled.

Is this setting from the app side?

Right now, it is not possible to force enable delegates when running custom models, this functionality will be added in the next benchmark version.
