description	A system is provided that includes a plurality of processors connected to a shared storage via an asynchronous storage interface that includes various interface logic and a ring counter that performs polling of the processors for access to the shared storage. The ring utilizes a "lookahead" feature that bypasses stages in the ring to speed up responses to request signals from the processor. The logic uses the clock from the particular processor accessing the shared memory at any point in time.
