Saving power in a mobile terminal includes determining alignment processing moments after the mobile terminal enters a standby mode. Alignable wakeup events, which occur during alignment processing periods corresponding to each alignment processing moment, are thus controlled to commence related processing at each of the alignment processing moments. Power consumption caused by various wakeup events in a standby mode may thus be reduced and battery life of the mobile terminal may thus be improved.

An apparatus and method for servicing multiple graphics processing channels are described. In one embodiment, a graphics processing apparatus includes a scheduler configured to direct servicing of a graphics processing channel by issuing an index related to the graphics processing channel. The graphics processing apparatus also includes a processing core connected to the scheduler. The processing core is configured to service the graphics processing channel by: (i) correlating the index with a memory location at which an instance block for the graphics processing channel is stored; and (ii) accessing the instance block stored at the memory location.

A system and method for modifying the configuration of one or more graphics adapters and one or more displays without rebooting the system allows a user to quickly transition between different graphics adapter/display configurations. A single display driver interfaces between the operating system and the one or more graphics devices. The display driver reconfigures the one or more graphics devices to change the adapter/display configuration without shutting down or rebooting the system. Unlike a conventional system reboot performed by the operating system, the display driver checks that there are no memory leaks or error conditions during the reconfiguration.

Software can freeze portions of a pipeline operation in a processor by asserting a predetermined freeze register in the processor. The processor halts operations relating to portions of a common pipeline processing in response to an asserted freeze register. Processor resources that operate downstream from the common pipeline continue to process any scheduled instructions. The processor is prevented from initiating any context switching in which a processor resource is allocated to a different channel. The processor stops supplying any additional data to downstream resources and ensures that the interface to downstream resources is clear of previously sent data. The processor prevents state machines from making additional requests. The processor asserts an acknowledgement indication in response to the freeze assertion when the processing has reached a stable state. Software is allowed to manipulate states and registers within the processor. Clearing the freeze register allows processing to resume.
