ABSTRACT:
The execution status of pipeline processing is highly visualized by appropriately displaying processes forming loops in a simplified manner. A loop-information storage unit stores loop-defining information specifying the address of an instruction that causes a pipeline process forming a loop. An operation-information storage unit stores operation information that includes the address of an instruction input into a pipeline and information indicating the execution status of a pipeline process caused by the instruction. A loop determination unit determines whether each pipeline process indicated by the operation information forms a loop by referring to the loop-defining information. An output unit outputs visualization information indicating, in a visually comprehensible manner, the execution status of a pipeline process that has been determined to form a loop for a predetermined number of executions of the loop and the execution status of a pipeline process that has been determined to form no loop.
