Abstract

A convolution calculation apparatus applied for convolution calculation of a convolution layer includes a decompression circuit, a data combination circuit and a calculation circuit. The decompression circuit decompresses compressed weighting data of a convolution kernel of the convolution layer to generate decompressed weighting data. The data combination circuit combines the decompressed weighting data and non-compressed data of the convolution kernel to restore a data order of weighting data of the convolution kernel. The calculation circuit performs calculation according to the weighting data of the convolution kernel and input data of the convolution layer. Since the compressed weighting data of the convolution kernel is transmitted to the convolution calculation apparatus in advance, the compressed weighting data is first decompressed and then convolution calculation is performed accordingly, hence reducing the storage amount and transmission bandwidth used by the convolution kernel in an electronic apparatus.
