Title:
CALCULATION CIRCUIT, CALCULATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/053835
Kind Code:
A1
Abstract:
In an embodiment, provided is a calculation method of a convolution layer in a convolution neural network. The calculation method is provided with: a step for generating a coefficient matrix (A) by converting a kernel used in the convolution layer so as to correspond to an input vector (x) obtained by deploying, in a row, a feature map input to the convolution layer; a step for searching for non-zero elements included in the coefficient matrix; a step for taking, as a processing unit, a multiplication of each non-zero element included in the coefficient matrix and a corresponding element of the input vector, and allocating the multiplication to each of a plurality of calculators (CL) which can perform parallel processing, so as to equalize the number of processing units in each calculator; and a step for sequentially executing, by each calculator, the multiplications allocated thereto and integrating the multiplication results to a corresponding element of an output vector (f).
