TFA does directly mention the NPU "Arm-China Zhouyi: 30 TOPS (Dedicated)"

"you cannot simply use standard versions of PyTorch or TensorFlow out of the box. You must use the NeuralONE AI SDK."

Neon is a SIMD instruction set for the CPU, not a separate accelerator. It doesn't need an SDK to use, it's supported by compiler intrinsics and assembly language in any modern ARM compiler.

Quite right, I mixed up Neon with NN:
