Neuromorphic processor and neuromorphic processing method

Abstract

A neuromorphic processor and a neuromorphic processing method are provided. The neuromorphic processor includes a plurality of neuromorphic elements, a message exchange facility, and a computation unit. The plurality of neuromorphic elements each has a respective state memory entry for storing their state. The message exchange facility enables neuromorphic elements to transmit neural event messages, and to receive transmitted neural event messages. A neural event message includes a message type indicating that the neural event message is an accumulation message or a leakage message. An accumulation message instructs the computation unit to modify a state value of a 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.
