Neural Networks in FPGA

I have a PhD student (Jihan Zhu) working in this area. There have been many 
implementations of NN's in FPGAs over the years. The first seems to have 
been
Cox, C.E. and E. Blanz, GangLion - a fast field-programmable gate array 
implementation of a connectionist classifier. IEEE Journal of Solid-State 
Circuits, 1992. 28(3): p. 288-299.

A very brief (4 page) survey appeared in FPL in 2003:
J. Zhu and P. Sutton, "FPGA Implementations of Neural Networks - a Survey of 
a Decade of Progress," in Proceedings of 13th International Conference on 
Field Programmable Logic and Applications (FPL 2003), Lisbon, Sep 2003.

I saw a paper maybe 10 years ago on a neural net set up in an FPGA 
(small by todays standards),  It used bit serial arithmetic and was able 
to fit more nodes than one might have thought.  IIRC, this was an early 
xilinx 4K family.

You might google "Federico Faggin" (my boss at Zilog 26 years ago) or
Synaptics, his later company...
