SYSTEM AND METHOD FOR ENABLING CLOCK STRETCHING DURING OVERCLOCKING IN RESPONSE TO VOLTAGE DROOP

Methods and apparatuses control the clock rate of a processing unit. The methods and apparatus control the clock rate by generating an output clock rate based on the determined frequency adjustment such that the processing unit maintains the overclocking. The methods include: receiving an analog vol...

Zusammenfassung:Methods and apparatuses control the clock rate of a processing unit. The methods and apparatus control the clock rate by generating an output clock rate based on the determined frequency adjustment such that the processing unit maintains the overclocking. The methods include: receiving an analog voltage supply in response to detecting overclocking in the processing unit; dynamically sensing measurements of an output voltage from a voltage generator based on the received analog voltage supply; determining characteristics of a voltage droop in the output voltage based on the dynamically sensed output voltage measurements; determining a frequency adjustment for the clock rate of the processing unit based on the determined characteristics of the voltage droop; and generating an output clock rate based on the determined frequency adjustment such that the processing unit maintains the overclocking.
