Claim 1:
2. The two-dimensional photonic neural network convolutional acceleration chip based on series connection structure according to claim 1, wherein, the coupling coefficient of the microring resonators in the M microring delay weighting units is controlled by the convolution kernel matrix control signal, specifically:
the coupling coefficient of the microring resonators is determined according to the convolution kernel matrix coefficient and the initial signal strength of each wavelength in the multi-wavelength optical signal, and the coupling coefficient of the microring resonators is changed by the thermo-optical effect or electro-optical effect; theN microring resonators in each of the microring delay weighting units correspond to a row of coefficients in the convolution kernel matrix, and the M×N microring resonators in the M microring delay weighting units correspond to the two-dimensional convolution kernel matrix coefficients of size M×N.
