What is an "inference"?
[Alison Wang] The inference here means machine learning inference. It is th=
e process of
running data points into a machine learning model to calculate an output su=
ch as a single=20
numerical score. For example, we use this driver, user space application an=
d Cortex-M firmware
to complete an inference about image classification.

Where are the userspace tools (if any) that are needed for this driver to w=
ork properly?
[Alison Wang] You could refer to https://github.com/nxp-imx/ethos-u-driver-=
stack-imx.git .
