Abstract (en)
[origin: WO2017186830A1] The invention proposes a device for distributing convolution coefficients of at least one convolution kernel of a convolutional neural network, carried by an input bus (201), to a set of processing units in a calculator based on a convolutional neural network architecture. The device comprises at least one permutation network (30) controlled by at least one control unit (32), the permutation network comprising a set of permutation units (30) arranged to perform circular offsets of at least a portion of the input bus. For each convolution kernel, each control unit is configured to dynamically control at least some of the permutation units of the permutation networks (30) in response to an input event applied to the convolution kernel and at least one parameter representing the maximum size of the convolution kernels.
