1. A device for generating a look up table, wherein the device is applied to a first terminal instrument, comprising a processor;
the processor is configured for acquiring a plurality of target input values contained in each target dimension, wherein the target dimension is a dimension contained in a target look up table to be generated, and the number of the target dimensions is one or more;
determining a target output value corresponding to each target input value contained in each of the target dimensions;
calculating a target difference value corresponding to each target input value contained in each of the target dimensions according to a preset rule, each target input value contained in each of the target dimensions and the target output value corresponding to each of the target input values; and
generating the target look up table according to a mapping relationship between each target input value contained in each of the target dimensions and a target difference value corresponding thereto;
the processor is specifically configured for determining a target prediction value corresponding to each target input value according to each target input value contained in the target dimension or the target output value corresponding to each of the target input values; and respectively calculating a difference value between the target output value corresponding to each of the target input values and the target prediction value so as to obtain a target difference value corresponding to each of the target input values;
the processor is specifically configured for,
when the target input value is a first target input value among the plurality of target input values contained in the target dimension, determining a preset reference value as the target prediction value corresponding to the target input value; and
when the target input value is an Nth target output value among the plurality of target input values contained in the target dimension, determining a target output value corresponding to a preamble target input value as the target prediction value corresponding to the target input value, wherein the preamble target input value is an (N−1)th target input value among the plurality of target input values; and
the processor is further configured for transmitting the preset rule and the target look up table to a second terminal instrument, so that after the second terminal instrument finds a target difference value corresponding to each look up input value in the target look up table according to the look up input value corresponding to each of the target dimensions, a target output value corresponding to each of the look up input values is calculated according to the preset rule, a plurality of the look up input values and the target difference value corresponding to each of the look up input values.
