Abstract:
A queue length arbiter system for selecting from a plurality of queues requiring access to a resource, said system comprising:a first weight circuit connected to a first queue; a second weight circuit connected to a second queue; an arbiter circuit connected to said first weight circuit and said second weight circuit, said arbiter circuit selectively granting access to a resource; wherein said first weight circuit provides a first weight signal to said arbiter circuit, said first weight signal based upon an amount of data packets in the first queue; and wherein said second weight circuit provides a second weight signal to said arbiter circuit, said second weight signal indicative of an amount of data packets in said second queue; and wherein said arbiter circuit grants higher priority access to a selected one of said first queue and said second queue based upon the volume of data packets in the first and second queues, with higher priority being granted to the one of the first and second queues having a greater amount of data packets therein, as determined by the first and second weight signals.
