Abstract
A logic circuit for use as an arbiter to arbitrate among N devices of a computer system for access to a shared resource. The arbiter generates state variables to represent arbitration win information. The state variables are generated through the use of request for arbitration signals input to the arbiter, present values of the state variables and internally generated intermediate arbitration win signals to provide a cost effective, efficient implementation of the logic required for the arbitration in a smaller physical solution for the arbitration logic.
