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

摘要

Multi-channel audio communication in a Serial Low-power Inter-chip Media Bus (SLIMbus) system is disclosed. In this regard, in one aspect, a multi-channel output port is provided in a SLIMbus system. The multi-channel output port receives an audio stream from an audio source (e.g., a storage medium) via a direct memory access (DMA) pipe and distributes the audio stream to multiple receiving ports (e.g., speakers) over multiple data channels, all connected to the single multi-channel output port. In another aspect, a multi-channel input port is provided in a SLIMbus system. The multi-channel input port connects to multiple data channels from multiple distributing ports (e.g., microphones). By providing the multi-channel output port and/or the multi-channel input port in a SLIMbus system, it is possible to support multiple data channels with a single DMA pipe, thus improving implementation flexibilities and efficiencies of the SLIMbus system.
