Abstract

The present application discloses a convolutional neural network binarization method and an operation circuit, which solve the problems of low operation efficiency and slow speed in the prior art. A convolutional neural network binarization method, which convolves the convolution kernel and feature map through an AND gate. Accumulate the results of the convolution operation. Normalize the data accumulated by the convolution operation to be between (‑1, +1). The normalized result is binarized into 1 and 0, and the binarized result is kept or inverted. Perform a pooling operation on the maintained or negated result, and output the result of the operation. The invention also provides a convolutional neural network binarization operation circuit based on the binarization method. By using an AND gate to replace the original multiplier and XNOR gate, not only the resource consumption is less, but the calculation speed is also higher. quick.

Description

technical field [0001] The invention relates to a convolutional neural network circuit, in particular to a convolutional neural network binarization method and an arithmetic unit. Background technique [0002] Convolutional Neural Networks have been continuously developed and have applications in various applications such as image recognition, natural language processing, speech recognition, etc. Convolutional neural networks usually contain a large number of parameters and require a lot of computation, which limits their application in the field of edge computing. The binary neural network is obtained by binarizing the ordinary convolutional neural convolution kernel, input data, and activation value. The method for binarizing a convolutional neural network in the prior art: the data greater than or equal to 0 is quantized as +1, and the data less than 0 is quantized as -1. Corresponding to this binarization method, the XNOR operation can be used to replace the multiplier...
