ABSTRACT:
A computer system incorporating an apparatus for allocating exclusive shared resource requests includes a shared resource, a first type device coupled to the shared resource and a second type device coupled to the shared resource. The computer system also includes an arbitrator unit coupled to the shared resource capable of granting the second type device exclusive access to the shared resource by preventing the first type device from being granted exclusive access to the shared resource. The arbitrator unit prevents the first type device from being granted exclusive access to the shared resource for at least a duration of time after the second type device has completed an associated second type shared resource transaction.
