Carver Mead's "Analog VLSI and Neural Systems" for where neuromorphic computing started. Intel's Loihi papers (Mike Davies et al.) for where it is now. Our paper takes a different path — constraints instead of neurons.

Thank You. I see those (and more) at the wikipedia entry for NC.

Any books you can recommend? I see a bunch on Amazon but not sure which are the good technical ones. Something with more information about the various hardware approaches (eg. non-ISA/hybrid/etc.) would be welcome.
