Abstract
Techniques for accounting microprocessor resource consumption. The present invention provides an automatic method to timely determine the current microprocessor clock frequency. Information provided by timer facilities of the microprocessor is reused by sampling this information at constant intervals. Such direct derivation of the microprocessor clock frequency is a real-time method that also takes into consideration secondary effects. Examples for such secondary effects include clock frequency variations across chips due to manufacturing variations, any degradation due to performance loss by thermal, or other detrimental effects as well as any voltage changes. In the preferred embodiment of the invention, the real-time microprocessor clock frequency determination is implemented as part of the microprocessor itself. No additional service processors or other external hardware facilities are needed in order to control the microprocessor clock frequency determination function.
