Snap Inc Granted Patent for Neuromorphic Processor
Summary
USPTO granted Snap Inc. Patent US12602228B2 for a neuromorphic processor and neuromorphic processing method. The processor includes a plurality of neuromorphic elements with state memory entries, a message exchange facility for transmitting and receiving neural event messages, and a computation unit. Neural event messages are classified as accumulation messages (instructing addition/subtraction of values) or leakage messages (instructing reduction of state values correlated with the current state). The patent contains 20 claims and was filed on March 26, 2020.
What changed
USPTO granted Patent US12602228B2 to Snap Inc. for a neuromorphic processor and associated processing method. The patent discloses a system comprising multiple neuromorphic elements with state memory, a message exchange facility enabling transmission and receipt of neural event messages, and a computation unit that modifies state values based on message instructions. Accumulation messages instruct the computation unit to add or subtract values from destination neuromorphic elements, while leakage messages instruct reduction of state values by a leakage amount correlated with the current state. The patent contains 20 claims and was filed on March 26, 2020.
The grant establishes enforceable intellectual property rights for Snap Inc. in the field of neuromorphic computing. Technology companies and research institutions developing brain-inspired processing systems should consider this patent as prior art. The neuromorphic processor technology covered by this patent may impact future innovation in AI hardware, neural network implementations, and energy-efficient computing architectures.

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.
