Abstract
PURPOSE: To increase the processing speed with broad range of branched address, by producing the address of the next microinstruction, through the replacement of the non-use filed of microinstruction with an arbitrary part or all of the micro instruction addresses.
CONSTITUTION: The micro μ program read out is set to the μ instruction data register 9, the type of this μ instruction is classified with the decoder 10, and the selection signal 11 is fed to the selectors 12W15. Further, to the decoders 16W19, the signal of a given bit of μ instruction set to the register 9 is fed to select the selectors 20W23 with the respective decoders 16W19. Further, the output data selected from the selectors 20W23 is fed to the input gate A of the selectors 12W15, and empty address of a given bit of the register 9 is fed to the input gate B. Further, the next instruction address from the incrementor 24 inputting the address outputted from the μ instruction address register 25 is fed to the gate C of the selectors 12W15 and the address of the next μ instruction is produced, enabling to obtain broader range of branched addresses.
