Audio buffering system and method of buffering audio in a multimedia receiver
Abstract:
An audio buffering system in a multimedia receiver includes an audio interface coupled to an incoming audio signal for generating a digital audio signal having transmitted therein a plurality of data words; a first-in-first-out (FIFO) buffer being coupled to the digital audio signal and comprising a plurality of cells being organized sequentially for holding data words of the digital audio signal, wherein a first cell of the FIFO buffer has an input being coupled to the digital audio signal; and a first shift register having a plurality of bits being organized serially, wherein a first bit of the first shift register receives an output from a last bit of the first shift register, and each bit of the first shift register is coupled to a corresponding bit in an outputted data word of the FIFO buffer. The first shift register is loaded with data words outputted from the FIFO buffer.
