ABSTRACT:
A data processor which has instructions of operation and comparison when including the signed binary number represented by complement on 2 as the object and has a flag correctly representing the result of the operation as positive or negative regardless of whether or not overflow occurs so as to correlate the arithmetic operation close with a status flag change, thereby facilitating mathematical interpretation of the result of the operation.
