How to specify VsiNpu as Computational Backend for a custom built C/C++ application on NXP i.MX8

Hi,

I am trying to execute a custom built C++ application using ARMNN on i.MX8. How to specify it to use VsiNpu as the backend for Computation. Currently it works with CpuAcc Backend where this is specified when creating the context for a specific compute device.

Thanks & Regards,

Divya

Hi,

It seems you choose the backend like this (for VsiNpu) before loading the network :

armnn::IOptimizedNetworkPtr optNet = armnn::Optimize(*network, {armnn::Compute::VsiNpu}, runtime->GetDeviceSpec());
