GROUPED CONVOLUTION PROCESSING OPTIMIZATION DEVICE AND GROUPED CONVOLUTION PROCESSING OPTIMIZATION METHOD

Abstract: the device includes a first unit that executes at least one of a column process that inserts (m−n/g) columns of zeros at the right end of an i-th weight for each i from 1 to g or a row process that inserts (m−n/g) rows of zeros at the bottom of the i-th weight for each i from 1 to g, when a constraint that requires convolution computation to be executed on data composed of m channels for a grouped convolution is imposed and a second unit that executes at least one of an input weight process that inserts (m−n/g) columns of zeros to the right of the i�n/g-th column of the input weight for each i from 1 to g or an output weight process that inserts (m−n/g) rows of zeros below the i�n/g-th row of the output weight for each i from 1 to g.
