Abstract
A direct memory access (DMA) engine receives an instruction corresponding to a packet of a message and indicating a traffic class identifier (ID). The engine stores an entry for the instruction in a tracker, a respective tracker entry comprising a traffic class ID and indicators of whether the respective entry requires processing, a transfer of a DMA payload is complete, and is actively transferring the DMA payload. The engine arbitrates among the entries, by: determining a current mask indicating entries currently excluded selection; updating the current mask in cycles in response to detecting remaining tracker entries which require processing, have sufficient available output queue credit for the traffic class ID, and are not currently masked; and identifying the winning tracker entry based on the current mask and the indicators for the entries. The system forwards information associated with the winning tracker entry in response to meeting a priority level.
