Claim 0:
1. A convolution calculation apparatus, applied for convolution calculation of a convolution layer, the apparatus comprising:
a decompression circuit, decompressing compressed weighting data of a convolution kernel of the convolution layer to generate decompressed weighting data;
a data combination circuit, combining the decompressed weighting data and non-compressed data of the convolution kernel to restore a data order of weighting data of the convolution kernel;
a calculation circuit, performing calculation according to the weighting data of the convolution kernel and input data of the convolution layer; and
a conversion circuit, coupled between the data combination circuit and the calculation circuit, performing format conversion on the weighting data of the convolution kernel, and outputting the converted weighting data to the calculation circuit.
