Claim:
A lookup table addressing system having a set of lookup tables in an external memory comprising: a data address generator including an input register for receiving a data word from a compute unit, the data word comprising a plurality of sections, each section comprising a reference to an entry in a table in the set of lookup tables and at least one deposit-increment index register having a table base field for identifying a location of the set of lookup tables in said external memory, a table index field identifying a location of a specific table in the set of lookup tables, and a displacement field for identifying a location of a specific entry in the specific table, said data address generator configured to deposit a section of the plurality of sections of said data word into said displacement field to access a partial result corresponding to said data word section before incrementing said table index field and depositing remaining sections of said data word to retrieve partial results corresponding to the remaining sections of said data word for each table in the set of lookup tables.
