ABSTRACT:
A pipeline processor comprises a memory stage arithmetic unit, a data dependence detecting unit and a control unit. The data dependence detecting unit outputs a detection signal to the control unit when it detects the data dependent relationship between a load instruction LD and a subtraction instruction SUB to be executed next thereto. The control unit receives the detection signal to control such that load data to be loaded from a memory unit according to the load instruction LD is inputted to the memory stage arithmetic unit. The memory stage arithmetic unit executes subtraction by using the load data in a memory stage of the subtraction instruction SUB.
