Packetized audio data operations in a wireless local area network device

A Wireless Local Area Network (WLAN) transceiving integrated circuit that services voice communications in a WLAN with at least one WLAN device, the WLAN transceiving integrated circuit comprising:

• a WLAN interface that wirelessly communicates with the at least one WLAN device;
• an output buffer operably coupled to the WLAN interface that receives packetized audio data and that transmits the packetized audio data to the WLAN interface;
• an output buffer controller operably coupled to the output buffer and to the processor;
• and
• wherein when the output buffer satisfies a buffer vacancy threshold, the processor and the output buffer controller cooperatively operate to fill at least a portion of the output buffer with packetized audio data.

A method for processing packetized audio data by a Wireless Local Area Network (WLAN) device that wirelessly communicates with another WLAN device, the method comprising:

• receiving packetized audio data from the another WLAN device;
• writing the packetized audio data to an input buffer;
• reading packetized audio data from the input buffer;
• converting the packetized audio data read from the input buffer to Pulse Code Modulated (PCM) audio data;
• writing the PCM audio data to an audio Coder-Decoder (CODEC);
• determining that the input buffer satisfies a buffer vacancy threshold;
• and
• when the input buffer satisfies the buffer vacancy threshold, operating a processor and an input buffer controller of the WLAN device in cooperation to fill at least a portion of the input buffer with packetized audio data.
