1. An image processing controller for a display device, comprising a fixed-point circuitry and a plurality of neural network blocks cascaded sequentially, wherein the fixed-point circuitry is electrically connected to each neural network block, and configured to receive a feature signal corresponding to an output feature map about the display device from each neural network block, perform fixed-point processing on the feature signal to acquire fixed-point data within a design accuracy range, and input the fixed-point data as an input feature map to a next-level neural network block;
wherein a first input end and a second input end of the fixed-point circuitry are configured to receive a convolutional layer indication signal and the feature signal respectively; and
the fixed-point circuitry is configured to determine a corresponding neural network block in accordance with the convolutional layer indication signal, determine a design fixed-point range of the corresponding neural network block in accordance with a design fixed-point range of each neural network block, and perform the fixed-point processing on the feature signal in accordance with the design fixed-point range of the corresponding neural network block, so as to acquire the fixed-point data within the design accuracy range.
