1. One or more circuits, comprising:

  • an audio codec;

    a digital signal processor (DSP) operatively coupled to the audio codec;

    a second processor; and

    a memory that is shared by at least the second processor and the DSP,wherein the one or more circuits are configured to support multiple wireless communication protocols and multiple antennas,wherein the one or more circuits are configured to support separate processing paths for at least a general audio path, a voice path and a polyphonic ringer path before mixing the supported, separate processing paths,wherein the one or more circuits are configured to decimate a multi-level digital input signal by M, where M is an integer that is greater than or equal to 2, andwherein the one or more circuits are configured to generate an output digital signal having a number of signal levels greater than the multi-level digital input signal by processing the decimated multi-level digital input signal.
