Abstract

The invention provides a convolutional neural network calculation method and device and a computer readable storage medium, and the method comprises the steps: determining a data volume ratio of input image data to weight data for a target convolutional layer of a convolutional neural network; and determining a preset processing mode of the target convolutional layer according to the data volume ratio, so that the calculation platform performs convolution calculation of the target convolutional layer based on the preset processing mode of the target convolutional layer. By utilizing the method, the preset processing mode suitable for the target convolutional layer is determined according to the data volume ratio, so that the access bandwidth requirement of the external memory can be reduced.

Description

technical field [0001] The invention belongs to the field of deep learning, and in particular relates to a convolutional neural network calculation method, device and computer-readable storage medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] For common embedded platforms, without considering the external memory, the chip itself does not have enough storage space for storing these input and output feature maps (intermediate results of operations), as well as huge weight parameters, making the external Unavoidable frequent data transfer between the memory (usually DRAM) and the inside of the chip. [0004] Therefore, large-scale data exchange between the chip's internal and external memories will cause a lot of power consumption waste during the convolution calcula...
