Embodiment Construction
[0022] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.
[0023] The configurable general-purpose convolutional neural network accelerator designed by the present invention is as figure 1 As shown, the size of the two PE arrays is 14*16, the size of the convolution kernel is 3*3, the step size of the convolution kernel is 1, the size of the input feature map is 15*15 (after adding padding), and a single batch of input channels The number is 14, the number of output channels in a single batch is 32, and the data multiplexing mode is output multiplexing as an example to describe its working method in detail.
[0024] After the accelerator in the waiting state receives the start signal. The accelerator reads the network parameters from the external memory through the bus interface, updates the network parameter register, and determines the data reuse mode and the switching sequence of the working state accor...
