摘要：
A method for operating a program-controlled unit has two redundantly operable microprocessor cores and a comparator unit provided downstream from the two microprocessor cores. One working register having a different content is provided in each of the two microprocessor cores for the redundant operation, and the content of these working registers is fed to the downstream comparator unit in order to verify whether the comparator unit signals a difference.
