Abstract
PURPOSE: To avoid useless processing time, when execution is processed by branching every element of the conditions to be executed.
CONSTITUTION: The operational control unit 1 is the center of the electronic computer system and performs the control of each sub-system. Various input and output units are connected to the input and output control unit 2 and they are controlled with the unit 2. Further, the unit 2 can perform direct memory access to the main mamory control unit 5, which performs the control of the main memory unit 6. The main memory unit 6 is provided with the microprogram instruction, and the format of the instruction is shown in the diagram. Where the operation mode is OP, condition mode is CM, and branch condition is BC, and the common mode CM corresponds to various modes such as AND mode and OR mode etc. This system corresponds to the OR mode and the OR mode is selected as the condition mode.
