NEUROMORPHIC PROCESSOR AND NEUROMORPHIC PROCESSING METHOD

摘要

A neuromorphic processor and a neuromorphic processing method are provided comprising plurality of neuromorphic elements (i=1,...,i=n), a message exchange facility (20), and a computation unit (30). The plurality of neuromorphic elements has a respective state memory entry (10_j) for storing their state. The message exchange facility (20) enables neuromorphic elements to transmit neural event messages, and to receive transmitted neural event messages, a neural event message including an indication (NA) of one or more neuromorphic elements selected as the destination, a message type (MT) and one or more message parameters (MP1,...,MPm). The computation unit (30) is to update the state dependent on received neural event messages. The message type is one of at least an accumulation message (A) and a leakage message (L). An accumulation message instructs the computation unit to modify the state value of the destination neuromorphic element by addition or subtraction of a value indicated as a message parameter in the accumulation message. A leakage message instructs the computation unit to modify the state value by reduction of the state value with a leakage value that is correlated with the state value and which may be further dependent on one or more leakage parameters contained in the leakage message.
