摘　　要：重点介绍了Motorola的DSP563xx芯片中为各种音频后处理技术的实现所提供的开放式结构(PPPChain),它为开发者及客户(第三开发方)提供了良好的开发环境。It is a trend to support a Multi-Channel Multi-Decoder system on a single DSP chip, which has been addressed and implemented in Motorola's DSP 563xx. This 7.1-channel system integrates multiple audio decoders(Dolby Digital1,DTS2,MPEG,PCM)as well as numbers of post phase process. This paper focuses exclusively on the open architecture of PPP Chain which presents a flexible development environment for developer and custom(the third party)to implement sorts of post phase processing.
