摘要： An FMA unit, for carrying out an arithmetic operation in a model computation unit of a control unit, is configured to process input of two factors and one summand in the form of floating point values, and provide a computation result of such processing as an output variable in the form of a floating point value. The FMA unit is designed to carry out a multiplication and a subsequent addition, the bit resolutions of the inputs for the factors being lower than the bit resolution of the input for the summand and the bit resolution of the output variable.
