Abstract
A method for deep-sleep mode operation is described. The method includes initiating a quick-boot to exit from a deep-sleep mode of a system-on-chip (SoC) having multiple cores. The method also includes restoring a configuration saved by a last core prior to entry of the SoC into the deep-sleep mode. The method further includes enabling the last core that configured the SoC for the deep-sleep mode. The method also includes enabling the multiple cores and drivers to transition the SoC to an active mode.
Claims22
A method for deep-sleep mode operation, the method comprising:
- initiating a quick-boot to exit from a deep-sleep mode of a system-on-chip (SoC) having multiple cores;
- restoring a configuration saved by a last core prior to entry of the SoC into the deep-sleep mode;
- enabling the last core that configured the SoC for the deep-sleep mode;
- and
- enabling the multiple cores and drivers to transition the SoC to an active mode.
A non-transitory computer-readable medium having program code recorded thereon for deep-sleep mode operation, the program code being executed by a processor and comprising:
- program code to initiate a quick-boot to exit from a deep-sleep mode of a system-on-chip (SoC) having multiple cores;
- program code to restore a configuration saved by a last core prior to entry of the SoC into the deep-sleep mode;
- program code to enable the last core that configured the SoC for the deep-sleep mode;
- and
- program code to enable the multiple cores and drivers to transition the SoC to an active mode.
