Can this really be everything publically known about the ANE? Sounds hard to believe, I would have thought someone would have reverse engineered something about it by now.

My question too. This semi-answer on the page seems to contradict itself (source: https://github.com/hollance/neural-engine/blob/master/docs/p... ):

"> Can I program the ANE directly?

Unfortunately not. You can only use the Neural Engine through Core ML at the moment.

There currently is no public framework for programming the ANE. There are several private, undocumented frameworks but obviously we cannot use them as Apple rejects apps that use private frameworks.

(Perhaps in the future Apple will provide a public version of AppleNeuralEngine.framework.)"

The last part links to this bunch of headers:

So might it be more accurate to say you can program it directly, but won't end up with something that can be distributed on the app store?

Correct. (It is also unlikely that Apple exposes the Neural Engine directly.)

See other commenter above about GeoHot's analysis which is much more in depth.
