Abstract
A network switch configured for switching data packets across multiple ports uses decision making logic to generate frame forwarding information. The decision making logic employs a pipelined architecture that enables multiple data frames to be processed simultaneously to increase data throughput. The decision making logic also pipelines access to an address lookup table that stores the data forwarding information. An arbitration circuit provides the decision making device with automatic access to the address table in alternate time slots and also enables other circuits to access the address table in predetermined time slots.
