Reconfigurable Neural Net Chip with 32K Connections

H.P. Graf, R. Janow, D. Henderson, and R. Lee AT&T Bell Laboratories, Room 4G320, Holmdel, NJ 07733 Abstract We describe a CMOS neural net chip with a reconfigurable network architecture. Itcontains 32,768 binary, programmable connections arranged in 256 'building block' neurons. Several'building blocks' can be connected to form long neurons with up to 1024 binary connections or to form neurons with analog connections. Single-or multi-layer networks can be implemented withthis chip. We have integrated this chip into a board system together with a digital signal processor and fast memory.
