Abstract
An apparatus and method are disclosed for providing higher radix redundant digit lookup tables for digital lookup table circuits. A compressed direct lookup table unit accesses a redundant digits lookup table that is capable of providing a high order part and a low order part that can be directly concatenated to form an output numeric value. The redundant digits lookup table of the invention is structured so that no output overflow exceptions are created. A redundant digits lookup table recoder capable of providing recoded output values directly to partial product generators of a multiplier unit is also disclosed.
