METHOD FOR EFFICIENT ACCESS OF DATA STORED IN A NEXUS TABLE USING QUEUE TAG INDEXES IN A TABLE PORTION

Entries for data transactions are stored in and accessed from a nexus table. Data transactions over a bus are identified using a first reference. Further, data transactions may be additionally identified using a second reference. When a data transaction is identified only by a first reference, an entry for the data transaction is stored in a location within a first portion of the nexus table. Entries in the first portion of the nexus table are indexed using the first reference for the data transaction. When a data transaction is identified using both a first reference and a second reference, an entry for the data transaction is stored in a location within a second portion of the nexus table. Entries in the second portion of the nexus table are indexed using the second reference number for the data transaction. The first reference is not used in indexing entries in the second portion of the nexus table.
