ABSTRACT:
A wireless local area network (WLAN) transceiving integrated circuit includes a WLAN interface, an input buffer, an input buffer controller, and a processor. The WLAN transceiving integrated circuit may also include an output buffer, an output buffer controller, a transcoder, and/or an audio Coder-Decoder (CODEC). The WLAN transceiving integrated circuit is installed in a WLAN device that services voice communications. The input buffer receives packetized audio data from the WLAN interface. When the input buffer satisfies a buffer vacancy threshold, the processor and the input buffer controller cooperatively operate to fill at least a portion of the input buffer with packetized audio data. The processor copies packetized audio data from the input buffer and fills the input buffer with the copied packetized audio data to maintain an audio pattern in the input buffer. The input buffer controller fills the input buffer when the processor is available and after copying/filling is no longer effective. The processor operates to maintain the audio pattern when additional packetized audio data is received by the WLAN interface. These operations are also performed for the output buffer, which receives packetized audio data from the transcoder and writes the packetized audio data to the WLAN interface.
