A Low- cost Multi-standard Audio Decoder Architecture Design
At present, audio decoder in multimedia processing chip must support multi-standard, such as AC-3, MP3, WMA.Many methods, from software to hardware can be used to implement the architecture. In this paper, an architecture based on Embedded Processor core is proposed to support multi-standard audio decoding. Embedded Processor core is used for real-time audio decoding and rendering. Featured with preload method, multi-standard audio decoder could be extended easily. Further more, data and instruction memory could be updated during Embedded Processor core works, so on-chip data and instruction memory could be reduced largely,which means very low cost. As we can see from the experiment result, audio decoder based on this architecture could support current popular audio standards real-time at very low cost.
