Method, system, and apparatus for dynamic clock adjustment
View Patent ↗A method, apparatus, article of manufacture, and system, the method including, in some embodiments, determining an impedance of a power distribution network of a load for a range of frequencies, and adjusting a functionality of the load based on a relationship between the impedance of the power distribution network for the range of frequencies and the functionality of the load.
1. A method of managing a power distribution network, comprising:
powering on a device coupled to the power distribution network, the device receiving a clock signal and the power distribution network including a voltage regulator to supply power to the device; and
initiating a test of the device upon power-on, the test including:
determining impedance related data based on the operation of the device, the impedance related data based on voltage information and clock speed information;
storing the impedance related data over a range of operating conditions;
evaluating the operation of the device based on the stored impedance related data; and
adjusting the operation of the device based on the evaluation.
2. The method of claim 1 , wherein initiating the test of the device upon power-on comprises:
initiating a self-test of the device upon power-on.
3. The method of claim 2 , wherein the self-test is performed automatically upon power-on of the device.
4. The method of claim 3 , wherein the device includes a processor.
5. The method of claim 3 , wherein the device includes a multi-core microprocessor.
6. The method of claim 3 , wherein the device includes a core of a multi-core microprocessor.
