Convolutional neural network system

A convolutional neural network method includes: determining a temporary buffer layer between a first layer and a final layer of a convolutional neural network system; in a first stage, convolution operation is executed from a first layer to a temporary buffer layer of the convolutional neural network system according to part of input data of a previous level of the temporary buffer layer so as togenerate a feature map line; and in the second stage, executing convolution operation from the temporary buffer layer to the final layer of the convolutional neural network system to generate a feature map. 一种卷积神经网络方法，其包含：决定一暂时缓冲层，其位于卷积神经网络系统的第一层与最终层之间；于第一阶段，从卷积神经网络系统的第一层至暂时缓冲层，根据该暂时缓冲层之前层级的部分输入数据，执行卷积操作以产生一特征图线；及于第二阶段，从卷积神经网络系统的暂时缓冲层至最终层，执行卷积操作以产生一特征图。
