Support for Armnn?

[FNsi]

Tried to build an onnxruntime backend and found this.

Arm NN is the most performant machine learning (ML) inference engine for Android and Linux, accelerating ML on Arm Cortex-A CPUs and Arm Mali GPUs. This ML inference engine is an open source SDK which bridges the gap between existing neural network frameworks and power-efficient Arm IP.

Arm NN outperforms generic ML libraries due to Arm architecture-specific optimizations (e.g. SVE2) by utilizing Arm Compute Library (ACL). To target Arm Ethos-N NPUs, Arm NN utilizes the Ethos-N NPU Driver. For Arm Cortex-M acceleration, please see CMSIS-NN.
