DROOP PROTECTION METHOD AND CIRCUIT
This abstract first appeared for US patent application 18925373 titled 'DROOP PROTECTION METHOD AND CIRCUIT
Original Abstract Submitted
The present techniques relate to mitigating droop conditions over state transitions in systems having dynamic voltage and frequency scaling and there is disclosed a method of controlling a dynamic voltage and frequency scaling circuit, comprising: initiating a transition from a first voltage and frequency state to a second voltage and frequency state; switching activity from a first nominal source to a first fallback source; retuning the first nominal source to become a second fallback source at the second voltage and frequency state; switching activity from the first fallback source to the second fallback source; retuning the first fallback source to become a second nominal source at the second voltage and frequency state; and switching activity from the second fallback source to the second nominal source.
