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: A method includes sending data from a first serial low-power inter-chip media bus (SLIMbus) component to a second SLIMbus component. The method further includes sending the data via at least a first SLIMbus data line of a plurality of SLIMbus data lines.

Abstract: 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.

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.
