STAGED POWER DISTRIBUTION CONTROL

摘要

Various embodiments are directed to restrictions in portable computing device electric power to accommodate reductions in the voltage level of a power source. An apparatus comprises a controller caused to receive configuration data from a main processor circuit specifying a voltage level threshold and selected action to take to reduce electric power to a first component in response to the voltage level falling below the first voltage level threshold, recurringly monitor the voltage level; based on the voltage level falling below the first voltage level threshold, take the first selected action and transmit a signal to the main processor circuit indicating that the voltage level has fallen below the first voltage level threshold and that the first selected action has been taken; transmit the voltage level to the main processor circuit; receive a signal from the main processor circuit to undo the first selected action; and so undo.

主权项

1. A controller comprising: logic, at least a portion of which is implemented in hardware, to:
receive configuration data from a main processor circuit that specifies a first voltage level threshold and a first selected action to take to reduce electric power provided to a first component to provide a first feature in response to a voltage level of a power source falling below the first voltage level threshold; based on the voltage level of the power source falling below the first voltage level threshold, take the first selected action, and transmit a signal to the main processor circuit that indicates that the voltage level of the power source has fallen below the first voltage level threshold and the first selected action has been taken; and based on the voltage level of the power source rising above the first voltage level threshold after falling below the first voltage level threshold, await a debounce period and transmit a signal to the main processor circuit that indicates that the voltage level of the power source has risen above the first voltage level threshold.
