Neuromorphic processing system and method of operating the same

A neuromorphic processing system comprising a plurality of neuromorphic processing clusters, each one of the plurality of neuromorphic processing clusters being coupled to a message exchange network for exchange of event messages, each one of the event messages comprising a destination indication and an event message payload, wherein a neuromorphic processing cluster of the plurality of neuromorphic processing clusters comprises:

• a message receiving facility to receive an event message from the message exchange network;
• a message transmitting facility to transmit an event message via the message exchange network;
• a neuromorphic processor having;
• a set of state memory entries, each state memory entry being configured for storing a value representative of a neuromorphic state associated with a neuromorphic element, and
• a computation facility configured to update the neuromorphic state associated with each neuromorphic element of one or more neuromorphic elements indicated as a destination in the destination indication of a transmitted event message, and
• wherein the message receiving facility comprises a pattern header memory,
• wherein the message receiving facility is configured to:
• provide the event message to a plurality of neuromorphic elements in accordance with a pattern specified in the pattern header memory by retrieving from the event message a reference to the pattern header memory, to
• use the reference to retrieve from the pattern header memory an indication for a set of neuromorphic elements that a destination of the event message, and
• compute a respective address of the neuromorphic elements in the set from that indication and the neuromorphic element destination indication.
