Abstract

PURPOSE: To reduce the number of microsteps and also to obtain high-speed processing by using a microinstruction string in common by controlling the operation code of an arithmetic controller by firmware instructions.
CONSTITUTION: Through selector 9, condition register 10 stored with a specific bit right before by a microinstruction in execution at that time makes a decision on whether the microinstruction stored in ROS data register 3 or the instruction in execution register 8 should be executed. Setting to execution resister 8 is done at the 1st step of instruction processing by way of logical operation circuit 5 and the Y bus. Consequently, a string of microinstructions can be made in common only by adding a little hardware such as execution register 8, condition code register 10 and selector 9.
