Neural network hardware circuitry and data selection methods, chips, and electronic devices

Abstract

This application relates to a hardware circuit for neural networks and a data selection method, a chip, and an electronic device, belonging to the field of neural networks. The hardware circuit for neural networks includes: an input data multiplexer, an actuator, and an output data multiplexer, with the actuator located between the input data multiplexer and the output data multiplexer. The input data multiplexer is used to select external input data or internal data of the hardware circuit for use as the input data source according to a first selection control signal. The actuator includes at least one layer of corresponding custom hardware circuitry in the neural network. The output data multiplexer is used to select whether to output the output data of the actuator as external data or as the internal data according to a second selection control signal. This application can reduce the circuit area and power consumption during the hardware implementation of neural networks.
