摘要： A communication control apparatus includes search information associated with a tree structure. A mask prefix is associated with at least one entry, each entry including information on the mask length of a mask prefix associated therewith and a sort key. Each entry is assigned to a node in the tree structure according to a sorting order. Each node is linked to a different node at the next lower hierarchy via a branch based on the entry of the node. A destination address of the packet received is first extracted, and a search target node specified by a search control for an entry having information on the best matched prefix of the extracted address is then searched for. After completion of the node-by-node search process, a transfer route is determined for the packet received based on the longest prefix amongst the most appropriate prefixes of all the current search target nodes.

摘要： Upon implementing a data registration into or a data retrieval from a data table (3) where first item data are registered along with corresponding second item data, there are used a first pointer table (1) where pointers to part of the registered data in the data table are registered in storage positions that are designated by hash values obtained by applying a first hash function (6) to the first item data of the part of the registered data, and a second pointer table (2) where pointers to the other registered data in the data table are registered in storage positions that are designated by hash values obtained by applying a second hash function (22) to the first item data of the other registered data.

摘要： This graphics system has a geometric sub-system that does not have to take into consideration memory resources for the raster sub-system of the graphics system. The graphics system sequentially receives from a host computer system data sets that define a graphic object and downloads texture data for graphics from the host computer system, so that geometric processing and rasterization are performed on the graphic object for display on a computer screen.
