Abstract

An integrated circuit (IC) includes a first processing module that converts inbound data into an inbound digital audio signal and converts an outbound digital audio signal into outbound data. A second processing module performs a user application that includes at least one of generating of an inbound analog audio signal and generating an outbound analog audio signal. A third processing module performs an operating system algorithm to coordinate operation of at least one user application.
