Abstract
A system has a shared resource, such as a bus or memory, with which various devices may communicate upon a request being granted by an arbiter. In order to reduce the arbitration time, the arbiter is comprised of a state machine and latch which run asynchronously. Consequently, once one request has been granted and acted upon, the state machine will commence arbitration for any remaining requests.
