    Abstract: 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.

    Abstract: Techniques of this disclosure provide for adjustment of a conversion rate of a sampling rate converter (SRC) in real-time. The SRC determines relative timing of generated output samples based on non-approximated integer components that are recursively updated. The SRC may further base relative timing of output samples on a value of one or more step size components associated with the integer components. Also according to techniques of this disclosure, a conversion rate of an SRC may be adjusted in real-time based on a detected mismatch between a source clock of a digital input signal and a local clock.

    Abstract translation: 本公开的技术提供了实时调整采样率转换器（SRC）的转换速率。 SRC根据递归更新的非近似整数分量来确定生成的输出采样的相对时序。 SRC可以进一步基于与整数分量相关联的一个或多个步长分量的值来输出输出样本的相对时间。 同样根据本公开的技术，可以基于检测到的数字输入信号的源时钟与本地时钟之间的失配来实时地调整SRC的转换速率。

    Abstract: Multi-channel audio communication in a Serial Low-power Inter-chip Media Bus (SLIMbus) system (300) is disclosed. A multi-channel output port (302(X)) 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 (308) and distributes the audio stream to multiple receiving ports (234,238) (e.g., speakers) over multiple data channels (316L,318R), all connected to the single multi-channel output port. A multi-channel input port is also provided in the SLIMbus system. The multi-channel input port connects to multiple data channels from multiple distributing ports (e.g., microphones). It is thereby possible to support multiple data channels with a single DMA pipe, thus improving implementation flexibilities and efficiencies of the SLIMbus system.

    Abstract translation: 公开了串行低功率片上媒体总线（SLIMbus）系统（300）中的多声道音频通信。 在SLIMbus系统中提供多通道输出端口（302（X））。 多通道输出端口经由直接存储器访问（DMA）管道（308）从音频源（例如，存储介质）接收音频流，并将音频流分配到多个接收端口（234,238）（例如，扬声器） 通过多个数据通道（316L，318R），均连接到单个多通道输出端口。 SLIMbus系统还提供多通道输入端口。 多通道输入端口从多个分配端口（例如麦克风）连接到多个数据通道。 因此，可以使用单个DMA管道来支持多个数据通道，从而提高SLIMbus系统的实施灵活性和效率。

    Abstract: Systems and methods relate to managing shared resources in a multithreaded processor comprising two or more processing threads. Danger levels for the two or more threads are determined, wherein the danger level of a thread is based on a potential failure of the thread to meet a deadline due to unavailability of a shared resource. Priority levels associated with the two or more threads are also determined, wherein the priority level is higher for a thread whose failure to meet a deadline is unacceptable and the priority level is lower for a thread whose failure to meet a deadline is acceptable. The two or more threads are scheduled based at least on the determined danger levels for the two or more threads and priority levels associated with the two or more threads.
