Abstract

The invention provides a basic computing unit and a computing method of a convolutional neural network. The basic computing unit includes a controller, an addition tree, an input buffer, several computing units, and an output buffer; the computing unit includes a block random access memory, Several convolution operation units, internal adders, activation pooling units. Based on the control of the controller, the input buffer loads the image data of the corresponding number of lines to each calculation unit, and the block random access memory sends the effective number of lines and the initial number of lines to each convolution operation unit so that it can obtain the image data of the corresponding number of lines; The convolution operation unit processes the image data and sends it to the addition tree through the internal adder; the addition tree processes the image data sent by each internal adder and sends it to an activation pooling unit; the activation pooling unit processes the image data and sends it to the output terminal cache. The solution can realize the algorithm based on hardware, so that the completion time of the algorithm can be controlled.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a basic calculation unit and a calculation method of a convolutional neural network. Background technique [0002] Convolutional Neural Networks (CNN) is an efficient recognition method that has developed rapidly and attracted widespread attention in recent years. [0003] Currently, the CNN algorithm can be implemented based on a CPU (Central Processing Unit, central processing unit) or a GPU (Graphics Processing Unit, graphics processing unit). Among them, both the CPU and the GPU implement the algorithm by software. [0004] Since the existing implementation method is to realize the algorithm by software, the time for completing the algorithm is uncontrollable. Contents of the invention [0005] The invention provides a basic calculation unit and a calculation method of a convolutional neural network, which can implement an algorithm based on hardware, so that the comple...
