SYSTEM STANDBY EMULATION WITH FAST RESUME

摘要

Systems and methods may provide for assuming control over a processor in response to an operating system (OS) request to transition the processor into a sleeping state and transitioning the processor into an intermediate state that has a shorter wake latency than the sleeping state. Additionally, the processor may be maintained in the intermediate state until a wake event is detected. In one example, one or more power lowering operations may be reversed in response to the wake event.

主权项

1. A computing system comprising:
a battery to supply power to the computing system; a processor to run an operating system (OS); a basic input/output system (BIOS) comprising:
an interceptor to assume control over the processor in response to an OS request to transition the processor into a sleeping state;a transitioner to transition the processor into an intermediate state that has a shorter wake latency than the sleeping state; anda wake unit to maintain the processor in the intermediate state until a wake event is detected.
