Abstract
A router including a lookup execution unit including a plurality of stages, a forwarding table memory arranged in hierarchy including addressable sectors, blocks, and entries, and a crossbar having an address crossbar for selectively coupling one of the plurality of stages to a sector of the memory so that data from the sector can be read. In one example, any one of the stages of the plurality of stages may be selectively and dynamically coupled with any one of the sectors of the forwarding table memory for providing an address to a particular sector of the memory to read data therefrom.
