Design and Hardware Implementation of Neural Systems
Abstract
This project had two major aims. One was is the design and computer simulation of specific neural circuits modeled after the early vision system of higher vertebrates. The second aim was the design and construction of electronic analog neural system that could be used for implementing such a vision system and possibly other neural systems. Our initial approach to the hardware implementation was to build an entirely hardwired system using Very Large Scale Integration assemblies of electronic neurons and separate resistive synapse connection matrices fabricated by CVD deposition of amorphous silicon. During further simulation studies of the vision system it became clear that at this early state of development a completely hardwired system would incorporate modifiable synapses and a programmable connection architecture. Rather than restrict the design of such a system by tailoring it to the specific architectures of the vision system, we decided to design a general purpose programmable neural analog computer that would be useful not only for vision but also for other task of real world computation and other problems suitable for neural computation.
