Abstract
The proper functionality of a first processor is checked with a second processor. The second processor thereby provides the first processor with a start value and a computation rule. The first processor carries out the specified computation rule using the predetermined start value, and returns a result to the second processor. The second processor checks the result against a stored comparison result. The computation rule is defined such that the basic instructions which are used for programming the first processor are checked.
