The processing device and method for adaptive extension lookup table provided by the embodiments of the present application store a first lookup table with high precision and large quantity in a first storage unit, and dynamically maintain a second lookup table with low precision and small quantity and an anchor scaling factor in a second storage unit. A processing unit dynamically resamples the first lookup table according to the actual value distribution of parameter input data, updates the output value of the second lookup table, and calculates the corresponding anchor scaling factor. When processing subsequent data, the input value is first mapped to the coverage range of the second lookup table by using the anchor scaling factor, and then the output value corresponding to the second mapping value is determined by table lookup. Thus, in the case of limited hardware storage resources, the value interval most active for the current data can be adaptively concentrated, that is, the interpolation precision of the main data region is improved without increasing the hardware cost, and the waste of storage resources caused by the fixed anchor distribution is avoided.
