That would still require a huge connector with a lot of pins. I can't think
of an application where USB or SPI (I've driven it sometimes at 25MHz) would
not suffice.

(Well, actually I can, but if one wants to build something with such a high
bandwidth requirement to the CPU, you're better off using an embedded
computer instead of a NN).

Un saludo.
