Self-arbitrating, self-granting resource access

摘要

An arbitration system and method provides self-arbitration among a plurality of processors or other entities vying for access to the bus or other shared resource. The entities vying for access to the shared resource present their respective priority values to an evaluation medium. The evaluation medium determines the highest priority value of those values presented, and provides this "winning" value to the competing entities. The entities compare the received "winning" value to their respective presented values. If an entity makes a positive comparison, that entity won the arbitration and is granted access to the shared resource.
