Abstract
Two flip-flops for carry information are provided in a data processor; one for carry of arithmetic operation and the other for carry occuring when a program counter is incremented. A state of the latter flip-flop provides a condition of a conditional branch instruction. With the provision of those flip-flops, a multidigit operation can be performed without increasing programsteps to save carry information attendant on the operation data. A simple program may be prepared without increasing hardware for skip instruction processing.
