ABSTRACT:
A microprogrammed computer comprises an instruction register for registering a machine instruction word; a decode read only memory (DROM) for storing the start address data of microprogram routines which correspond to machine instruction words, respectively, and the control bit data which correspond to the machine instruction words, respectively; and a read only memory (ROM) for storing a plurality of microprograms each consisting of microinstructions. The microprogrammed computer has such a hardware structure that each control bit datum in the DROM may serve to change the function of a microinstruction and the execution sequence of the microprograms in the ROM.
