Title:
SEMICONDUCTOR DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/242666
Kind Code:
A1
Abstract:
Provided is a semiconductor device having a small circuit scale and reduced power consumption. The semiconductor device comprises: a first computation unit that performs digital computation; and a second computation unit that performs analog computation. In the computation of a convolutional neural network, the computation of a convolutional layer is executed by the first computation unit, and the computation of a fully connected layer is executed by the second computation unit. Since the convolutional layer often uses the same filter value repeatedly, the first computation unit is configured to have one input of the same filter value and a plurality of inputs of data to be subjected to convolution processing, and simultaneously execute a plurality of product-sum computations. In addition, since the fully connected layer requires a weighting factor of the product of the number of input data and the number of output data, the second computation unit is configured to store a weighting coefficient of each computation cell in the computation cells arranged in a matrix, and transmit input data in each row direction to output output data from each column direction.
