Abstract

PURPOSE:To shorten the execution cycle of a mup (microprogram), by generating a mup address to be branched before determination of branch conditions in a mup controlled data processing device. CONSTITUTION:Two address generating circuits 1 and 2 independent of each other are provided and are controlled to start the calculation for a mup address, where contents should be executed next, before determining whether branch conditions are satisfied or not; and if the signal on a control signal line 7 designates a conditional branch, input terminals OE of address generating circuits 1 and 2 are switched to make the mup address transmittable.
