ABSTRACT:
A priority resolver shortens the time between a requesting circuit initiating a request for access to a requested circuit that is shared with other circuits and the requesting circuit actually functioning with the requested circuit. A first portion of the priority resolver circuit is associated with the requesting circuit and makes a request for access to another portion of the priority resolver circuit associated with the requested circuit before the first portion has chosen the highest priority one of a plurality of requesting circuits that have concurrently bid for access to the requested circuit. Before the portion of the priority resolver associated with the requested circuit can respond to the access request and return an access grant signal, the first portion of the priority resolver circuit has chosen the highest priority requesting circuit. In this manner the time for accessing requested circuits is decreased.
