  • Methods and apparatus for mapping fields of entries into new values and combining these mapped values into mapped entries for use in lookup operations such as for packet processing
    Patent number: 7313667
    Abstract: Fields of entries are mapped into new values with these mapped values combined into mapped entries for use in lookup operations typically for packet processing. One implementation identifies a list including multiple items each having a first field and a second field. The unique first and second fields of each item are respectively mapped to mapped first and second fields. A first associative memory is programmed with the unique first fields, and a first stage memory is programmed with the mapped first fields at corresponding locations. A second associative memory is programmed with the unique second fields, a second stage memory is programmed with the mapped second fields at corresponding locations. A second stage associative memory is then programmed, using the mapped first and second fields, with entries corresponding to one or more of the original multiple items.
