Patent ID: 8064967

Claim:
A radio frequency (RF) integrated circuit (IC) operable to support wireless communications, comprising: a plurality of processing modules wherein each processing module is operable to support one or more functions of the RF IC, wherein the plurality of processing modules include: a voice baseband processing module; a data baseband processing module; a RF section; and an interface module coupled to exchange symbol streams between the voice baseband processing module and the RF section when the RF IC is in a voice mode and between the data baseband processing module and the RF section when the RF IC is in a data mode; and a plurality of power islands, wherein: a power island of the plurality of power islands is associated with one or more functions, a processing module of the plurality of processing modules performs the one or more functions; and the power island provides power to the processing module based on activation of the one or more functions such that power is reduced when one of the one or more functions associated with the power island is not required.
