Pulse Coded Biologically Motivated Neural-Type MOS Circuits

Abstract

This project has two aspects, one for ONR and one for AFOSR. The ONR portion is devoted to obtaining hardware implementations for the physiological representations used in the program SYNETSIM developed by the neurophysiologist Dr. D. Hartline of Bekesy Laboratories. The AFOSR portion is for evaluation capabilities of the pulse code philosophy of neural networks. During the period covered by this report a number of results have been obtained, the following being the main accomplishments. ON the ONR portion of the research several chips have been fabricated for SYNETSIM pools and a neural arithmetic unit based upon the pools, while also a number of modifications have been made to SYNETSIM to make it a much more friendly user program. Several papers have been presented at international conferences and the DRIVER module continues under investigation for VLSI realization. Means to implement long term potentiation also continue under investigation. On the AFOSR portion, a significant result has been obtained, this being a means of realizing any Hopfield-type network via pulse coded circuits has been obtained and a paper on the result is under preparation.
