Abstract:
1. A method for monitoring an electronic control system, comprising: storing at least one of control commands and data as code in at least one memory; transferring the code, in a context of ongoing instruction accesses, via a word line out of the at least one memory to a control unit having a specific word width, the word width encompassing the code of a plurality of memory cells of the memory, an additional datum being created in each case for the code of a word width and being stored in the memory; checking an entire code of the at least one memory outside the ongoing instruction accesses by selecting exactly one memory cell for each word width, a complete word line being activated thereby; creating a check datum from code of the complete word line; and comparing the check datum with the stored additional datum; wherein the checking, creating, and comparing are performed by an ECC unit.
