Abstract
An arbitration circuit especially useful for SCSI-II applications, but also having other applications. The basic arbitration circuit requires only thirty NOR gates, one inverter, and connection to all but the lowest priority data line in order to have an arbitration circuit for sixteen lines. The basic circuit will arbitrate among up to sixteen units and is extremely compact and could be used on SCSI related integrated circuits in addition to other SCSI circuitry. The basic arbitration apparatus may also be expanded to accommodate a thirty-two line SCSI-II bus by extending the number of stages to thirty-two.
