Inspection method of the functionality of the calculation unit

(57) Abstract: second calculation unit gives advance calculations specified and the start value to the first calculation unit, a method for testing the functionality of the first calculation unit by a second calculation unit is provided that. The first computing unit to perform the calculations defined by a given pre-start value and returns the result to the second calculation unit. Second computing unit is compared with reference results are files this result. Rules for calculating, as the basic instructions used for programming the first calculation unit is examined, is constructed.
