What do you define as "hardware"?

I am talking about doing this in the NPUs that are available on the 
market today and in the future.

We're talking about these kinds of devices:

I'm afraid that your experience with CPU driven devices isn't a great 
match here, and we're talking past each other.

I would love to be able to use my employers purchasing power to drive 
demand on AQM, but I need to know what the requirements are, and that 
they're feasable to do, preferrably with an engineering effort for the 
vendor in the range of few man years. I can't produce this document 
myself, I have already tried pointing them in the direction of 
presentations etc, but I need "hard" documents, outlining exactly what 
they need to do.

Do we have this currently? In that case, whereto should I point them?
