Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A system, comprising:
a first power supply for a first power domain and a second power supply for a second power domain;
a controller configured to:
determine that image processing circuitry is operated in a reduced-power mode after being idle; and
generate one or more control signals in response to determining that the image processing circuitry is operated in the reduced-power mode; and

an always-on timing generator disposed in the second power domain, wherein the always-on timing generator is configured to:
determine that the image processing circuitry is operating in the reduced-power mode based on an indication that the first power supply is decoupled from the first power domain;
generate timing signals while the first power supply is decoupled from the first power domain; and
adjust routing circuitry based on the one or more control signals to transmit the timing signals generated by the always-on timing generator to a display driver integrated circuit disposed in an electronic display.
