Abstract

PURPOSE:To increase a processing speed of an instruction, by jumping without executing an unnecessary processing unit, and executing the next processing unit, in an information processor of a pipeline control system. CONSTITUTION:In an information processor for executing the pipeline processing, a selecting circuit SEL 10 is provided between a holding register AL 9 holding the information executing the processing of a prescribed machine instruction language, and a logical circuit TR 11 for executing a prescribed processing, and by said circuit, either a path shifting to processing T from processing A, or a path shifting to the processing T after processing D is selected. In case when the processing A is unnecessary and it is possible to jump to the processing T directly from the processing D, the path to the processing T from the processing D is selected, and the jump processing is executed.
