Abstract
PURPOSE: To ensure the constitution simply and with low cost, by avoiding the necessity to shunt the information stored in the fixed address area in advance and keeping the information of intermediate result for data processing in the main memory unit, in executing the office instruction.
CONSTITUTION: The data read out from the main memory unit MM is once stored in MDR 10 via the selector 110 and the output of MDR is fed to the bus. Further, the address information is stored in MAR 103 under the control of microprogram and the output is fed to MM as MM designation address. After the mask processing with PSW in PSWR 104 with input to the external interruption signal processing circuit 108, the said output is fed to the signal test circuit 109. The signal test circuit 109 collects the branch condition of microprogram among the signal of CPU each section and selects a given signal according to the designation of microinstruction to feed it to the sequence circuit.
