Systems and methods for managing current consumption by an electronic device

摘要

Systems and methods for managing current consumption by an electronic device are provided. The electronic device includes first and second clock units. The first clock unit generates a first reference clock signal based on a first current input. The second clock unit generates a second reference clock signal based on a second current input greater than the first current input. The system includes a control module configured to identify an application to be executed. The control module is configured to determine whether the application is associated with a first current consumption level or a second current consumption level greater than the first current consumption level. The control module is configured to select the first or second reference clock signal based on whether the application is determined to be associated with the first or second current consumption level. The system includes circuitry configured to execute the application based on the selection.

1. A system comprising:
at least one control circuit configured to:
identify an application to be executed;determine whether the application utilizes a first reference clock signal having a first accuracy or a second reference clock signal having a second accuracy that is greater than the first accuracy based at least in part on whether the application is associated with a first current consumption level or a second current consumption level greater than the first current consumption level and whether a sampling rate associated with the application is a terminating rational number multiple of a first frequency of the first reference clock signal or a second frequency of the second reference clock signal, the first reference clock signal being associated with the first current consumption level and the second reference clock signal being associated with the second current consumption level; andselect the first reference clock signal or the second reference clock signal based on whether the application is determined to be associated with the first current consumption level or the second current consumption level, wherein the first reference clock signal is generated based on a first current input, and wherein the second reference clock signal is generated based on a second current input greater than the first current input; and a circuitry configured to execute the application based on the selection.
