摘要： Lookup table addressing of a set of lookup tables in an external memory is achieved by: transferring a data word from a compute unit to an input register in a data address generator; providing in at least one deposit-increment index register in the data address generator including a table base field for identifying the location of the set of tables in memory, and a displacement field; and depositing a section of the data word into a displacement field in the index register for identifying the location of a specific entry in the tables.
