  • Patent number: 9104974
    Abstract: An apparatus and a method for transmitting and receiving a spike event in a neuromorphic chip. A transmission apparatus of the neuromorphic chip outputs addresses sequentially and repeatedly to an address bus, and when a spike generated by a neuron is detected by the transmission apparatus, outputs a strobe at a first time when one of the addresses being output sequentially and repeatedly becomes identical to an address of the neuron that generated the spike. A receiving apparatus of the neuromorphic chip inputs an address through the address bus at a strobe detection time when the strobe is detected by the receiving apparatus.
