Abstract
A novel table look-up/indirect addressing system and method uses a dual fetch Harvard architecture to accomplish one full table look-up access per instruction cycle. The offset access fetch, the indirect data fetch and the table offset and base address addition are all performed during a single cycle. The system and method also accommodate data accesses using packed (half word) offsets.
