Abstract
A relocation system to associatively search a database lookup table with a search key to addressably retrieve a corresponding associate content table record as a search result. The relocation system is implemented in search engine devices having associative memory (e.g., CAM) having one or more sections. The search engine devices employ relocation values when calculating addresses, one per section per device, with the relocation values optionally pre-calculated and stored in relocation registers. The search engine devices may be cascaded to construct a larger search engine. The search engine is typically used with a processor and addressable memory (e.g., RAM or ROM). In particular, the relocation system permits multiple databases to be concurrently stored and worked with in the associative and addressable memory.
