DVD audio decoder having a central sync-controller architecture

摘要: An audio decoder architecture makes use of various component sharing techniques to conserve hardware and reduce implementation cost. In one embodiment, the comprises a bitstreamer, synchronization controller, first second decode controllers, memory module, data path, an output buffer. The bitstreamer retrieves compressed provides token-aligned controller controllers. initially controls locate parse frame headers extract decoding parameters. initiates which corresponds identified compression format, turns control path over selected controller. then variable length code transform coefficients. coefficients are passed module operate under inverse produce digital data. If is successfully completed, asserts done signal, returns uneventfully
