Mobile systems with seamless transition by activating second subsystem to continue operation of application executed by first subsystem as it enters sleep mode

摘要

A computer system includes two or more subsystems. In one example, a first subsystem is executing a multimedia application using data stored in a first storage device. A copy of the data is also stored in a second storage device associated with a second subsystem. The second subsystem may be a dedicated multimedia player controller. When the first subsystem is to enter a sleep state, the second subsystem may continue to process the multimedia data stored in the second storage device. The second subsystem may also use the same audio port that the first subsystem was using before it enters the sleep state. Appropriate transition point may be determined by the second subsystem to ease audio disruption.

1. An apparatus comprising:
a second storage device of a second subsystem to store at least a subset of data being processed from a first storage device of a first subsystem to render content to a user while the first subsystem is in a relatively higher power normal operating state; and a processor to:
automatically process the at least subset of the data from the second storage device to continue rendering the content to the user when the first subsystem exits the relatively higher power normal operating state and enters a relatively lower power different operating state;enter the first subsystem back to the relatively higher power normal operating state;store in the second storage device of the second subsystem at least a subset of additional data from the first storage device when the first subsystem is back in the relatively higher power normal operating state;exit the first subsystem from the relatively higher power normal operating state to re-enter the relatively lower power different operating state when the at least subset of the additional data is stored in the second storage device; andautomatically process the at least subset of the additional data from the second storage device to continue rendering the content.
