Abstract:
1. A circuit arrangement comprising arbitration logic configured to grant access to a plurality of devices operatively connected to a bus by granting bus access to a first group of the plurality of devices according to a predetermined arbitration scheme for determining in which order the devices of the first plurality receive access to the bus relative to one another, automatically altering the predetermined arbitration scheme, and granting access to the bus for a second group of the plurality of devices according to the altered arbitration scheme, wherein the arbitration logic is configured to grant access to the bus for the first group of the plurality of devices by grouping requests associated with the first group of the plurality of devices to create a first pool and sequencing through each request of the first pool according to the predetermined arbitration scheme until access to the bus has been granted for each request of the first pool, and wherein the arbitration logic is configured to grant access to the bus for the second group of the plurality of devices by grouping requests associated with the second group of the plurality of devices and received subsequent to the requests of the first pool to create a second pool and sequencing through each request of the second pool according to the altered arbitration scheme until access to the bus has been granted for each request of the second pool.
