Abstract
PURPOSE:To shorten the machine cycle and to perform the pipeline processing at a high speed by interlocking a 1st flow in a pipeline process with no direct use of an STV signal and bypassing a 2nd flow to the 1st flow when an instruction extracting exception is detected. CONSTITUTION:In case of an SS (storage-and-storage) type instruction, a 1st flow is interlocked to a state following a state D by one or more states and also preceding a state E regardless of an instruction buffer valid signal (STV signal). Then the interlock of the 1st flow is released by the STV signal when an instruction extracting exception is detected after execution of a 2nd flow. Thus the 2nd flow is bypassed to the state E of the 1st flow or to a state preceding the state E. Thus it is possible to shorten the machine cycle and to perform the pipeline processing at a high speed.
