Zusammenfassung:An apparatus comprising a first sub-arbiter circuit and a second sub-arbiter circuit. The first sub-arbiter circuit may be configured to determine a winning channel from a plurality of channel requests based on a first criteria. The second sub-arbiter circuit may be configured to determine a winning channel received from the plurality of channel requests based on a second criteria. The second sub-arbiter may also be configured to optimize the order of the winning channels from the first sub-arbiter by overriding the first sub-arbiter if the second criteria creates a more efficient data transfer.
