Abstract
The invention relates to a method and apparatus for synchronizing at least one computer, having at least one monitoring circuit associated with this computer. The synchronization takes place through at least one transmitted signal (WDS) in the form of a double pulse from the computer (&mgr;C) to the peripheral components (PIC , PIC ), which contain the monitoring circuits. To that end, shortly after the computer (&mgr;C) is started up at system start or after an HW reset, the signal (WDS) is sent to the at least one peripheral component (PIC , PIC ). After this, the upper and lower limit of the signal sequence (WDS) to be regularly transmitted by the computer for the monitoring circuit are tested and therefore the function of the monitoring circuits is tested. As with the synchronization, the testing takes place with a reaction of the monitoring circuits by means of at least one acknowledgement signal (IRS , IRS , R).
