Neuromorphic computing circuit and method for control

A neuromorphic computing circuit comprising:

• a plurality of nodes that generate a spike, the spike including a counter for an existing time of the spike and information indicating a sender of the spike, the plurality of nodes including a first node and a second node;
• and
• a transmission array that forms a transmission path of the spike by connecting the plurality of nodes, wherein
• the transmission array comprises a plurality of transmission circuits, one or more of the plurality of transmission circuits on the transmission path of the spike forwarding the spike,
• each of the plurality of transmission circuits is configured to:
• update a value of the counter when forwarding the spike,
• set, when detecting meeting of a first spike transmitted from the first node to the second node and a second spike transmitted from the second node to the first node, a time difference calculated based on the values of the counters of the first spike and the second spike, into the first spike being forwarded, and
• the second node comprises a spike generation circuit being configured to
• specify one or more time differences equal or less than a first threshold among a plurality of time differences set in a plurality of spikes received from the transmission array,
• accumulate connection strengths each between one of the sender nodes of third spikes set the specified time differences therein and the second node, and
• generate a fourth spike when the result of the accumulating exceeds a second threshold.
