    摘要： A reconfigurable neural network circuit is provided. The reconfigurable neural network circuit comprises an electronic synapse array including multiple synapses interconnecting a plurality of digital electronic neurons. Each neuron comprises an integrator that integrates input spikes and generates a signal when the integrated inputs exceed a threshold. The circuit further comprises a control module for reconfiguring the synapse array. The control module comprises a global final state machine that controls timing for operation of the circuit, and a priority encoder that allows spiking neurons to sequentially access the synapse array.

    摘要： Aspects include a method for generating a signal in response to an event. The method includes receiving, from a clock signal generator, a clock signal, wherein the clock signal has a fixed clock period. The method further includes receiving an indication of a pulse and, responsive to receiving the indication of the pulse, generating an output comprising a high voltage having a starting time and an ending time. The starting time is a first time when the indication of the asynchronous event is received, and the ending time is a second time at one fixed clocked period from the starting time.
