Abstract:
An audio decoder which supports generation of simple sound effects, wherein the audio decoder comprises:an input buffer configured to receive and buffer audio data frames;a decoding module coupled to retrieve the audio data frames from the input buffer and configured to convert the audio data frames into a sequence of decoded audio samples;a first-in first-out buffer (FIFO) configured to receive sound effect audio samples generated by an external control component;a host interface coupled to the external control component to receive the sound effect samples and to receive decoding module configuration information, wherein the host interface is coupled to provide the sound effect samples to the FIFO, and coupled to provide the configuration information to the decoding module; andan output interface coupled to retrieve decoded audio samples from the decoding module and sound effect audio samples from the FIFO in response to an audio sample request clock, wherein the output interface is configurable to provide the retrieved sound effect audio samples to a digital-to-analog converter for conversion to an analog audio signal.
