Abstract
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.
