1. A model calculation unit for calculating a data-based function model in a control unit, comprising: at least one processor core which includes: a multiplication unit for carrying out a multiplication on a hardware side; an addition unit for carrying out an addition on the hardware side; an exponential function unit for calculating an exponential function on the hardware side; a memory in the form of a configuration register for storing hyperparameters and node data of the data-based function model to be calculated; and a logic circuit for controlling, on the hardware side, a calculation sequence in the multiplication unit, the addition unit, the exponential function unit and the memory in order to calculate the data-based function model.
