摘要： Multi-channel audio alignment schemes are disclosed. One aspect of the present disclosure provides for accumulation of audio samples across multiple related audio channels at an audio source. Related audio channels indicate their interrelatedness, and when all the related audio channels have data to transmit, the source releases the data onto the time slots of the Serial Low-power Inter-chip Media Bus (SLIMbus), such that the related audio channels are within a given segment window of the time slot. This accumulation is repeated at the boundary of every segment window. Similarly, accumulation may be performed at the audio sink. Components within the audio sink may only read received data if status signals from all related sinks indicate that predefined thresholds have been reached. By providing such accumulation options, audio fidelity is maintained across multiple audio data channels.
摘要翻译：公开了多声道音频对齐方案。本公开的一个方面提供了在音频源处跨越多个相关音频声道的音频样本的累积。相关音频通道指示它们之间的相互关系，并且当所有相关音频通道都有数据要传输时，源将数据释放到串行低功耗片间媒体总线（SLIMbus）的时隙上，使得相关音频通道在时隙的给定分段窗口内。这个累积在每个分段窗口的边界处重复。类似地，可以在音频接收器处执行累积。如果来自所有相关接收器的状态信号指示已达到预定义阈值，则音频接收器内的组件只能读取接收到的数据。通过提供这样的累积选项，跨多个音频数据信道保持音频保真度。

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.
摘要翻译：公开了串行低功耗片间媒体总线（SLIMbus）系统中的多通道音频通信。就这一点而言，在一个方面中，在SLIMbus系统中提供多通道输出端口。多声道输出端口经由直接存储器存取（DMA）管道从音频源（例如，存储介质）接收音频流，并且通过多个数据信道将音频流分发到多个接收端口（例如扬声器），全部连接到单个多通道输出端口。另一方面，在SLIMbus系统中提供多通道输入端口。多声道输入端口连接来自多个分配端口（例如麦克风）的多个数据信道。通过在SLIMbus系统中提供多通道输出端口和/或多通道输入端口，可以用单个DMA管道支持多个数据通道，从而提高SLIMbus系统的灵活性和效率。
