A method includes receiving a plurality of requests to perform accesses for associated DMA channels and arbitrating the requests. The arbitration includes selectively granting a given request of the plurality of requests based at least in part on an associated fixed priority of the request and an associated priority weighting of the request. The priority weighting regulates which request or requests of the plurality of requests are considered at a given time.

Arbitrating direct memory access channel requests

A method includes processing descriptors to control a direct memory access (DMA) channel. The method includes synchronizing at least part of the processing, which includes processing a first descriptor of the descriptors to cause the execution to selectively pause based on a trigger value.

Direct memory access descriptor-based synchronization

A method includes processing a direct memory access (DMA) descriptor in a DMA controller. The method includes storing first data of the DMA descriptor at an address that is identified by second data of the DMA descriptor.
