Embodiment Construction

[0056] In order to make the design solution of the present invention more clear, the implementation of the examples of the present invention will be described in detail below in conjunction with the drawings in the examples of the present invention.

[0057] The present invention is the accelerated hardware realization of the forward propagation discrimination process of the convolutional neural network, including the convolutional layer and the pooling layer of the convolutional neural network. Among them, the formula of the convolutional layer is:

[0058]

[0059] Among them, l represents the number of layers, a l Represents the output tensor, * represents convolution, b represents bias, M represents the number of sub-matrices, σ represents the activation function, generally Relu.

[0060] The pooling layer formula is

[0061] a l =pool(a l-1 )

[0062] Among them, pool refers to the process of reducing the input tensor according to the pooling area size and pooling...

Abstract

The invention discloses a universal convolution-pooling synchronous processing convolution kernel system, and belongs to the technical field of convolution neural network acceleration in machine learning. An existing machine learning method is realized by adopting software, so that the problems of limited computing power, higher cost and the like exist. According to the present invnetino, the machine learning is realized by adopting the hardware design, the purpose of accelerating the convolutional neural network is realized in a convolutional-pooling synchronous processing manner, and the machine learning can be realized quickly and efficiently with low power consumption on the premise that the accuracy is not changed. According to an existing convolutional neural network, a convolution kernel is generally of a fixed size and cannot adapt to various design requirements, but the convolution kernel of the invention can change the parameters such as the size and the step length of the convolution kernel and can adapt to the design requirements under various conditions.
