Convolution operation device and convolution operation method

Abstract

The subject of the present invention is a convolution operation device and a convolution operation method. The convolution operation device includes a convolution operation module, a memory and a buffer device. The convolution operation module has a plurality of convolution units, each convolution unit performs a convolution operation based on a filter and a plurality of current data, and retains part of the current data after the convolution operation; the buffer device is coupled to the memory and the convolution The operation module obtains a plurality of new data from the memory, and inputs the new data to the convolution unit, and the new data is not repeated with the current data.

Description

technical field [0001] The present invention relates to a convolution operation device, in particular to a convolution operation device suitable for data streams. Background technique [0002] Deep learning is already one of the important application technologies for artificial intelligence (AI). Among them, Convolutional Neural Network (CNN) is a deep learning efficient recognition technology that has attracted widespread attention in recent years. Compared with other deep learning architectures, especially in the field of pattern classification, such as image and speech recognition, the convolutional neural network avoids complicated pre-processing, and can directly input the original image or raw data, thus obtaining more It is widely used and can achieve better recognition results. [0003] However, the convolution operation is a very performance-consuming operation. In the application of the convolutional neural network, especially the convolution operation and contin...
