Claim 1:
2. A convolution calculation apparatus, applied for convolution calcalution 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; and
a calculation circuit, performing calculation according to the weighting data of the convolution kernel and input data of the convolution layer,
wherein the weighting data of the convolution kernel comprises first-part data and second-part data, the compressed weighting data corresponds to the first-part data and the non-compressed weighting data corresponds to the second-part data.
