  • Patent number: 6681313
    Abstract: In a system for conducting virtual address translation in a virtual memory system and implementing a table such as a Translation Lookaside Buffer, a system and method enabling quicker access to tables entries in which the entries are addressed after adding a plurality of address parts wherein the plurality is two (2) or (3). Particularly, a smaller and/or faster adder is used having, for example, only n=2 ports in the time critical path. In order to make the exact address calculation, during array accesses, a multiplexor is implemented to decide, after the TLB arrays are accessed for preselection, which of a plurality of possible entries has to be taken.
