Abstract:
A multiport data communication system for transferring data packets between ports, the data communication system comprising:receive ports for receiving data packets from a plurality of network nodes, a decision making engine responsive to the received data packets for controlling transmission of the received data packets to at least one selected transmit port, the decision making engine including: an address table storage for storing an address table having address information relating to the ports, first and second logic circuits interacting with the address table storage for processing data blocks representing the received data packets in accordance with a prescribed algorithm, and an interleaved address table access circuit for enabling said first and second logic circuits to alternately access the address table, wherein the interleaved address table access circuit comprises an arbitration circuit for providing the first and second logic circuits with access to the address table in alternate time slots allocated to the first and second logic circuits.
