MULTI-CHANNEL AUDIO COMMUNICATION IN A SERIAL LOW-POWER INTER-CHIP MEDIA BUS (SLIMBUS) SYSTEM

摘要

Disclose the multi-channel audio communication between a kind of serial low-power chip in media bus (SLimBUS) system (300). Multichannel output port (302(x) is provided in SLIMBUS systems). Multichannel output port receives the audio stream from audio-source (for example). Storage medium, via direct memory access (DMA) (DMA) pipeline (308) and by audio stream be distributed to multiple receiving ports (234238) (such as, loudspeaker), pass through multiple data channel (316L, 318R), all these to be all connected to single multichannel output port. Multichannel input port is additionally provided in SLIMBUS systems. Multichannel input port is connected to multiple data channels from multiple dispatch ports (for example, microphone). Therefore, multiple data channels can be supported with single DMA pipelines, to improve the realization flexibility and efficiency of SLIMbus systems.
