HIGH- LEVEL SYNTHESIS METHOD AND STORAGE MEDIUM STORING THE SAME

A high-level synthesis method comprising the steps of converting an operating description describing one or more operations to a control data flow graph (CDFG) including one or more nodes representing the one or more operations and one or more I/O branches representing a flow of data, scheduling the CDFG obtained by the converting step, and allocating one or more logic circuits required for executing the CDFG obtained by the scheduling step. A portion of the CDFG in the converting step is subjected to logical synthesis in advance to generate a node, and the portion of the CDFG is replaced with that node.
