Claim 3:
4. The two-dimensional photonic neural network convolutional acceleration chip based on series connection structure according to claim 1, wherein, the N microring resonators in the microring delay weighting unit have a delay waveguide with a length of Δ1=c×Δt/nw between two adjacent microring resonators in the straight-through waveguide, where c is the speed of light in vacuum, nw is the effective refractive index of the delay waveguide, Δt=1/SM is the duration of a single symbol of the signal to be convolved, SM is the symbol rate of the signal to be convolved, and the length of the secondary delay waveguide is ΔL=(P−N+1)×c×Δt/nw.
