Patent ID: 7079657

Claim:
A system for performing digital multi-channel audio signal decoding, said system comprising: a sigma-delta analog-to-digital (A/D) conversion block operating on a composite analog audio signal to generate a composite digital audio signal; a clock generation block generating clock signals used in said multi-channel audio signal decoding; a DSP processing block including a multi-stage pipelined data path performing certain digital multi-channel audio signal processing functions in response to a set of instructions; an input buffer block connected between said sigma-delta A/D conversion block and said DSP processing block to transfer said composite digital audio signal to said DSP processing block; a configuration register block interfacing to at least said DSP processing block, said input buffer block, and said sigma-delta A/D conversion block; and an output buffer block interfacing to at least said DSP processing block and said clock generation block to output standard audio output signals at standard audio output rates.
