Abstract
PURPOSE: To increase a processing speed when a branch is not implemented, by comparing data while transferring the data to an arithmetic unit in two-machine cycles by a device which performs overlapping processing for instructions.
CONSTITUTION: The contents of a general register GR indicated by the part R1 of a branch instruction in an instruction register 107 and those of the GR indicated by the part R3 are added by an address adder 122 and while the addition result and the contents of the GR by the R3 or R3+1 are sent to a unit E, they are compared by a comparing circuit 130 to judge by a branch discriminating circuit 131 whether a branch should be implemented or not. Thus, the processing is speeded by one cycle in comparison with the case of the discrimination between the implement and nonimplement of the branch by performing the addition and comparison by the E unit.
