Abstract

An integrated circuit (IC) includes an RF section, a DSP, and a plurality of processors. The RF section and the DSP process an inbound RF signal to produce inbound data and process outbound data to produce an outbound RF signal. In addition, the DSP converts an outbound analog audio signal into an outbound digital audio signal and converts an inbound digital audio signal into an inbound analog audio signal. A first processor converts the inbound data into the inbound digital audio signal and converts the outbound digital audio signal into the outbound data. A second processor performs a user application that includes at least one of generation of the inbound analog audio signal and generation of the outbound analog audio signal and performs an operating system algorithm to coordinate operation of the user application.
