Abstract: Disclosed is an interface system including a first neuron cluster that outputs a first neuron signal including a first neuron request and first neuron data by performing a first arithmetic operation, and a first interface circuit that stores the first neuron data and outputs a first response, in response to the first neuron request. The first neuron cluster outputs a second neuron signal including a second neuron request and second neuron data by performing a second arithmetic operation, in response to the first response. Before the first data is transmitted to a second neuron cluster different from the first neuron cluster, the first interface circuit outputs the first response in response to a fact that the first neuron data is stored.
