Abstract (en)
[origin: WO2007057270A1] The invention relates to a method for operating a program-controlled unit with two redundantly operable microprocessor cores (110, 210; 120, 220) and a comparator unit (130, 230) which is mounted downstream from the two microprocessor cores. One respective working register (112, 212; 122, 222) having a different content is provided in the two microprocessor cores for redundant operation, the content of said working registers being fed to the downstream comparator unit (130, 230) in order to verify whether the comparator unit signals a difference.
