ABSTRACT:
A digital computing system includes an addressable read only memory for storing microprogram control words. A plurality of the microprogram control words each include a predetermined bit used for branching. When the predetermined bit within a control word is not set, the next microprogram control word is read from the next microprogram memory address. When the predetermined bit is set, the next microprogram word is read from the microprogram memory address having a value which corresponds to the next address plus a weighted value of the predetermined bit.
