A battery-optimized system-on-a-chip includes multimedia module, a
high-speed interface, a processing module, on-chip memory, and an on-chip
DC-to-DC converter. The multimedia module operably coupled to produce
rendered output data from input data received via the high-speed
interface and/or from data stored in the on-chip memory. The high-speed
interface is operably coupled to provide data to and from an external
source. The on-chip memory is operably coupled to store at least a
portion of a multimedia application, wherein the processing module
processes input multimedia data in accordance with the multimedia
application to produce output multimedia data. The on-chip DC-to-DC
converter is operably coupled to convert a battery voltage into a supply
voltage that is provided to the multimedia module, the high-speed
interface, the processing module, and/or the on-chip memory.
