DATA FLOW GRAPH GENERATION DEVICE, SETTING DATA GENERATION DEVICE, PROCESSOR AND DATA FLOW GRAPH GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To automatically generate a data flow graph corresponding to a reconfigurable processor capable of performing multiple length calculation.

SOLUTION: This data flow graph generation device has: an arithmetic bit number determination part determining the number of arithmetic bits necessary for calculation performed in a logic circuit of a reconfigurable circuit; and a node generation part generating a node corresponding to the calculation. The node generation part generates one node corresponding to one piece of calculation when the necessary number of the arithmetic bits is the number of arithmetic bits allowing the calculation or below, and generates a plurality of the nodes correspondingly to the one calculation when the necessary number of the arithmetic bits is larger than the number of the arithmetic bits allowing the calculation.
