<P>PROBLEM TO BE SOLVED: To provide a control system equipped with a pipeline arithmetic processor capable of solving the problem of an occurrence of a data path hazard and performing high-speed arithmetic processing concerning an access request to a shared memory shared by a plurality of processors. <P>SOLUTION: The pipeline arithmetic processor includes a pipeline processing part 2b and an instruction insertion control part 2a that refers to an instruction insertion and stage control information, and corrects the control information when there is an access request to an arithmetic processing execution memory 4. When the instruction insertion control part receives an access request instruction for requesting access to the arithmetic processing execution memory while executing a control program 4a, it inserts an NOP instruction in place of the access request instruction from an instruction decode part 2b2, executes the access request instruction while no operation is performed by the pipeline processing part, and successively continues to perform the pipeline processing. <P>COPYRIGHT: (C)2010,JPO&INPIT |
