ABSTRACT:
A binary number substitution mechanism includes first and second storage arrays addressed by first and second portions, respectively, of an input binary number, producing a substitute output binary number. The input binary number represents a predetermined number of microinstruction addresses in a read-only store, and the output binary number is representative of microinstruction addresses in a main storage device. Only a limited number of the possible input binary numbers are required to access the first and second storage arrays to read out selectively stored binary numbers to create a limited range of output binary numbers unique to each of the limited number of the input binary numbers.
