Original Abstract Submitted
The present techniques relate to mitigating droop conditions in systems having dynamic voltage and frequency scaling and there is disclosed a method of controlling a dynamic voltage and frequency scaling circuit, comprising: detecting a voltage droop relative to a current nominal voltage and frequency state; responsive to said current nominal voltage and frequency state having a corresponding fallback state in a safe operating zone of voltage and frequency, switching activity from a nominal source to a fallback source; and when a fallback to a safe operating zone is unavailable for said current nominal voltage and frequency state, pausing activity of the dynamic voltage and frequency scaling circuit.
