Abstract: Aspects for optimizing leaf comparisons from a tree search of data stored in external memory of an embedded processing system are described. The aspects include providing a control structure for leaf data comparisons as a control vector and a match key, and utilizing the control vector to direct types of comparison tests performed with the match key.

Abstract: Aspects for optimizing data searches in tree structures are described. The aspects include organizing multiple search levels of data into sub-trees contained in fixed size blocks of shared external memory of an embedded processing system, and requiring each reference to the data to proceed from one-half of a sub-tree during a descent of the search tree based on a search pattern.

Abstract: A network apparatus comprising storage units storing configuration information about the network apparatus, an input network interface to at least one network physical line, at least one processor receiving network data from said network interface, processing said data, storing information about said network data in said storage units, storing said data as formatted data units in said storage units, a first bus interface to two bus connections, a first hardware component reading said configuration information and said information about data stored in said storing units and steering said formatted data units stored in said storage units to at least one of the two bus connections of said first bus interface, a second bus interface to two bus connections, an output network interface to at least one network physical line, a second hardware component reading formatted data units arriving on at least one of the two bus connections of said second bus interface and storing said formatted data units in said storage un

Abstract: A network switch apparatus, components for such an apparatus, and methods of operating such an apparatus in which data flow handling and flexibility is enhanced by the cooperation among a plurality of interface processors and a suite of peripheral elements formed on a semiconductor substrate. The interface processors and peripherals together form a network processor capable of cooperating with other elements including an optional switching fabric device in executing instructions directing the flow of data in a network.
