"METHOD FOR OPERATING A PROCESSOR"

The present subject matter relates to method for operating a processor (2) that comprises at least two computation modules (4, 6). A signature register (18, 20) having a plurality of inputs is associated with each of least two of the at least two computation modules (4, 6). In the method, at least one function (12, 14) is carried out by the at least two of the at least two computation modules (4, 6). With each function (8, 10), an algorithm is calculated, wherein results (12, 14) calculated by each computation module (4, 6) are written into the associated signature register (18, 20) and the results (12, 14) written into the signature registers (18,20) are compared.
