ABSTRACT:
An information processor receives a residue number as an input and generates a mixed base number correspopnding to the residue number and a redundant residue digit corresponding to the residue number. The information processor includes a plurality of optical arithmetic and logic units (OALUs) arranged in channels and stages. Each digit of the residue number corresponds to a channel. Each channel produces a mixed base digit associated with the residue input number. The stages are serially arranged to successively generate mixed base digits corresponding to the residue number by performing modular multiplication and modular subtraction. Delay circuits are arranged parallel to the plurality of OALUs such that all of the mixed base digits are transmitted from the information processor at the same time. An additional channel of OALUs calculates the redundant residue digit based on the mixed base digits.
