Abstract
An apparatus is provided which comprises: a first Power Management Unit (PMU); and a second PMU, wherein the first PMU is to manage transition of the apparatus from a low power state to a first active state, wherein the second PMU is to manage transition of the apparatus from the first active state to a second active state, and wherein the second PMU is to be powered down while the apparatus is to be in the low power state.
Claims20
An apparatus comprising:
- a first Power Management Unit (PMU);
- and
- a second PMU,
- wherein the first PMU is to manage transition of the apparatus from a low power state to a first active state,
- wherein the second PMU is to manage transition of the apparatus from the first active state to a second active state, and
- wherein the second PMU is to be powered down while the apparatus is to be in the low power state.
3 more elements
A system comprising:
- a memory to store instructions;
- a processor coupled to the memory;
- first power management circuitry to control a voltage level and/or a frequency level for the processor;
- second power management circuitry to control switching on and/or switching off of the first power management circuitry;
- and
- a wireless interface to allow the processor to communicate with another device.
3 more elements
A device comprising:
- hierarchical power management architecture comprising:
- first power management circuitry that is to remain switched on during one or more low power states and one or more active states, and
- second power management circuitry that is to remain switched off during the one or more low power states and remain switched on during the one or more active states,
- wherein the device has a low duty cycle of operation.
