Quasi-fair arbitration scheme with default owner speedup.

摘要

A decentralized, pipelined, synchronous bus arbitration scheme which allows almost completely fair arbitration between multiple devices competing for the use of a communication bus while allowing the device that last used the bus faster access to the bus if no other device is competing for its use. The arbitration method and apparatus according to the present invention allows all devices that participate in arbitration equal access to the bus with the exception that when bus requests are posted simultaneously the device with the higher priority will always be granted use of the bus first.
