SYSTEM CLOCK MATCHING

摘要

A method for a control device comprising a processing device, an I/O module and a clock generator for providing a system clock, wherein the processing device and the I/O module are designed to operate with the system clock of the clock generator, comprises the steps of determining that capacity utilization of the processing device is exceeding a predetermined threshold, of determining that the I/O module is in a state in which a change in the system clock is uncritical, and of changing the system clock in order to match the performance capacity of the processing device to the capacity utilization.
