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

摘要

Channel audio communication in a serial low-power interchip media bus (SLIMbus) system 300 is initiated. A multi-channel output port 302 (X) is provided in the 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 308 and sends the audio stream to a plurality To the plurality of receive ports 234, 238 (e.g., speakers) via data channels 316L, 318R. A multi-channel input port is also provided in the SLIMbus system. A multi-channel input port connects to a plurality of data channels from a plurality of distribution ports (e.g., microphones). It is thus possible to support multiple data channels with a single DMA pipe, thus improving the flexibility and efficiency of implementation of the SLIMbus system.;
