    摘要: Arrays of neural cores are provided. Each neural core comprises ordered input wires ordered output wires, and synapses, each of the synapses operatively coupled to one of the input wires and one of the output wires. A plurality of signal wires is provided. At least one of the signal wires is disposed along each dimension of the array of neural cores. A plurality of routers is provided, each of which is operatively coupled to one of the neural cores and to at least one of the signal wires along each of the dimensions of the array of neural cores. Each of the routers selectively routes a signal from the at least one signal wire to its coupled neural core. Each of the routers selectively routes a signal from its coupled neural core to the at least one signal wire. The routers segment the ordered input wires and the ordered output wires into segments and independently routes the signals of each segment.

    摘要: A neuromorphic synapse array is provided which ensures that a neuron model as such McCulloch-Pitts is dependent on nonlinearity with a single polarity weight cell. The neuromorphic synapse array includes a plurality of synaptic array cells, a plurality of operation column arrays, and a reference column array. The synaptic array cells respectively have a single polarity synapse weight and are classified into operation synapse cells and reference synapse cells for shifting a product-sum of the operation synapse cells. The operation column arrays are defined by the operation synapse cells aligned in column of the array. The reference column array is defined by the reference synapse cells aligned in column of the array.
