Abstract
A method and apparatus for controlling access to a plurality of resources based on multiple received requests is provided. The system includes a priority register configured to receive each individual request, determine a priority for the request, and transmit the request to a priority appropriate path. A first high priority arbiter receives and arbitrates among highest priority requests in a round robin manner to determine a high priority suggested grant vector. At least one lower priority arbiter receiving and arbitrating among lower priority requests in a round robin manner to determine at least one lower priority suggested grant vector. Grant circuitry passes the high priority suggested grant vector unless said grant circuitry receives a low priority indication, whereby the grant circuitry passes a lower priority grant vector.
