  • System-on-a-chip incorporating artificial neural network and general-purpose processor circuitry
    Patent number: 11580355
    Abstract: A circuit system and a method of analyzing audio or video input data that is capable of detecting, classifying, and post-processing patterns in an input data stream. The circuit system may consist of one or more digital processors, one or more configurable spiking neural network circuits, and digital logic for the selection of two-dimensional input data. The system may use the neural network circuits for detecting and classifying patterns and one or more the digital processors to perform further detailed analyses on the input data and for signaling the result of an analysis to outputs of the system.
    Type: Grant

  • Conversion of digital signals into spiking analog signals
    Patent number: 11100389
    Abstract: A digital signal may be converted into a spiking analog signal. A different constant current may be applied to each of a plurality of switch circuits. Each bit of the digital signal may be applied to a corresponding one of the plurality of switch circuits. Each switch circuit may apply the corresponding constant current to a common output when the corresponding bit has a predetermined value. Each switch circuit may not apply the corresponding constant current to the common output when the corresponding bit does not have the predetermined value. A common current may be applied at the common output to a spiking neuron circuit.
