| Abstract: | 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. |
