Abstract
A method and apparatus for controlling access to a plurality of resources at a predetermined ratio based on multiple received requests. The system includes a series of multiplexors, adders, subtractors, multi-bit clocked registers, and comparators arranged to maintain the desired predetermined ratio. The registers act to maintain a first value correlated to a first quantity of requests granted for a first requester in excess of an amount desired according to the predetermined ratio and maintain a second value correlated to a second quantity of requests granted for a second requester with respect to the total requests desired from the second requester. One comparator compares the value from the first register with a predetermined value to assess whether to grant access to the first requestor.
