  • Publication number: 20140095923
    Abstract: Embodiments of the invention relate to faulty recovery mechanisms for a two-dimensional (2-D) network on a processor array. One embodiment comprises a processor array including multiple processors core circuits, and a redundant routing system for routing packets between the core circuits. The redundant routing system comprises multiple switches, wherein each switch corresponds to one or more core circuits of the processor array. The redundant routing system further comprises multiple data paths interconnecting the switches, and a controller for selecting one or more data paths. Each selected data path is used to bypass at least one component failure of the processor array to facilitate full operation of the processor array.

  • Patent number: 8473439
    Abstract: An integrate and fire electronic neuron is disclosed. Upon receiving an external spike signal, a digital membrane potential of the electronic neuron is updated based on the external spike signal. The electric potential of the membrane is decayed based on a leak rate. Upon the electric potential of the membrane exceeding a threshold, a spike signal is generated.

  • Publication number: 20130073497
    Abstract: An event-driven neural network includes a plurality of interconnected core circuits is provided. Each core circuit includes an electronic synapse array has multiple digital synapses interconnecting a plurality of digital electronic neurons. A synapse interconnects an axon of a pre-synaptic neuron with a dendrite of a post-synaptic neuron. A neuron integrates input spikes and generates a spike event in response to the integrated input spikes exceeding a threshold. Each core circuit also has a scheduler that receives a spike event and delivers the spike event to a selected axon in the synapse array based on a schedule for deterministic event delivery.
