ABSTRACT:
A method interfaces a plurality of bus requesters with a computer bus. The method apportions the bus bandwidth among the bus requesters by assigning to each bus requester a bus bandwidth portion that is based on the bandwidth of the bus requester. The method identifies a requester bandwidth for each of the bus requesters and sums the requester bandwidths to obtain a total bandwidth. The method determines, for each of the bus requesters, a weighting value representing the ratio of the bus requester bandwidth to the total bandwidth. The method apportions the bus bandwidth among the bus requesters by assigning each bus requester a bus bandwidth portion that reflects the weighting value of the bus requester. Apportioning the bus bandwidth based on the weighting values causes the requester bandwidth of each bus requester to be reduced by the same percentage when the bus saturates.
