PPROBLEM TO BE SOLVED: To pipeline loop processing in a CDFG (control data flow graph) with a minimum increase in area in a behavioral synthesis for synthesizing hardware from a behavior description. PSOLUTION: When the loop processing is pipelined, a loop control part 31 for outputting a control signal for making each node included in the loop processing perform at least a non-loop processing of the loop processing and the non-loop processing is provided within a loop processing part 30 of a control data flow graph showing that each node is divided for every pipelining stage, and the processing of each pipelining stage is executed in parallel every time the loop processing to be carried out in a plurality of times to generate the CDFG.
