摘要

The invention relates to a fma - unit (42) for carrying out an arithmetic operation a in a model calculation unit (3) in a control unit (1), wherein two receives as input variables and a summand in each case in the form of a fleece, decimal point value and can be processed as an output parameter of the calculation result in the form of a fleece, decimal point value is provided, wherein the fma - unit (42) is adapted to allow a multiplication and a subsequent addition to carry out, wherein the bit resolutions of the inputs for the multiplicand are lower than the bit resolution of the input for the summand and the bit resolution of the output variable.
