Method and system for audio CODEC voice ADC processing
First Claim
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.

Abstract
Methods and systems for audio CODEC voice ADC processing are disclosed. Aspects of one method may include using a decimating filter that may be enabled to generate 13 MHz, 9-level digital output signal from a 26 MHz, 3-level digital input signal. The 13 MHz, 9-level digital output signal may be processed for RF transmission, for audio output to an output device, and/or utilized for testing by a test fixture, for example. The 13 MHz, 9-level digital output signal may be further processed to generate a 6.5 MHz, 33-level digital signal. The 6.5 MHz, 33-level digital signal may be converted to an analog signal, and processed for audio output and/or testing. The 13 MHz, 9-level digital output signal may also be processed to generate a 40 KHz, 17-bit digital signal, which may be communicated to a test equipment or further processed for RF transmission.
