ABSTRACT:
A method and system interfaces a plurality of bus requesters with a computer bus having a bus bandwidth. The bus bandwidth is apportioned among the plurality of bus requesters by assigning to a selected bus requester a portion of the bus bandwidth based on how much the selected bus requester used the bus during a defined period. A bus controller determines how much the selected bus requester used the bus during the defined period by monitoring the use of the bus requester during the defined period. The bus controller assigns an initial bus bandwidth portion and a target use bandwidth portion. The bus controller compares how much the selected bus requester used the bus during the defined period to the target use bandwidth portion assigned to the selected bus requester. If the selected bus requester used the bus during the defined period more than the target use bandwidth portion, then the bus controller assigns to the selected bus requester a new bandwidth portion that is greater than the initial bus bandwidth portion. If the selected bus requester used the bus during the defined period less than the target use bandwidth portion, then the bus controller assigns to the selected bus requester, a new bus bandwidth portion that is less than the initial bus bandwidth portion.
