Abstract
A method for checking the operability of a digital signal processing unit of a position sensor, wherein the digital signal processing unit executes an instruction queue of N instructions one after another in sequences, wherein an additional number of x instructions is executed by the digital signal processing unit during each sequence, wherein the additional instructions are provided in a unit different from the memory, and that the results of the additional instructions are stored. The results of the additional instructions are read by a microcomputer. The results of the additional instructions are compared by the microcomputer with the expected results achieved by execution of identical additional instructions by the microcomputer or with expected results stored in the microcomputer. This includes a position encoder comprising a digital signal processing unit for calculating position information.
