Abstract
In a control unit, particularly for use in a motor vehicle, time measurement and time control should be independent of computer-specific cycle times. The control unit includes a quartz-controlled timer with a specified clock frequency and a global timer clocked by the quartz-controlled timer. The global timer furnishes a global timing pulse as a reference time for all the program parts of the computer. A plurality of dynamically managed program-controlled timers, which receive their clock signal from the global timer, are requested by the computer program each for one time measurement associated with a specific task. After the specific task is completed, the timer is available for further tasks.
