Abstract

A method and a device for monitoring a computer system which includes at least two processors. A first processor of the at least two processors monitors at least a second processor for correct functioning, by monitoring output signals of the second processor or the variables derived from it, at least with regard to their temporal sequence, their content, or their signal (wave) form. A relay of the output signals of the second processor to further units is blocked when the first processor, separately from the second processor, is placed in an energy-conserving operating mode.
