Abstract

A neuromorphic computing circuit includes nodes including first and second nodes generating a spike including a counter for a spike existing time and a sender information, and a transmission array including transmission circuits, one or more of which is on the transmission path and forwards the spike. Each transmission circuit updates a counter value when forwarding the spike and sets, when detecting meeting of a first spike from the first to the second node and a second spike from the second to the first node, time difference based on the counter values, into the first spike. The second node includes a generation circuit specifying time difference equal or less than a first threshold among ones in the received spikes, accumulating connection strengths between the sender of third spikes set the specified differences therein and the second node, and generating a fourth spike when the accumulating result exceeds a second threshold.
