Abstract

A method and a device are provided for performing switching and data comparison in a computer system having at least two processing units which each process data at a specified clock pulse, in which a switchover arrangement is provided and switching takes place between at least two operating modes, and a comparison unit is provided. A first operating mode corresponding to a compare mode is provided, and a second operating mode corresponding to a performance mode is provided. A synchronization arrangement is provided which assigns to the specifiable data a clock pulse information as a function of a processing unit, and at least the comparison unit takes into consideration this clock pulse information in the corresponding data.
