DATA FLOW GRAPH PROCESSING DEVICE, DATA FLOW GRAPH PROCESSING METHOD, AND DATA FLOW GRAPH PROCESSING PROGRAM

摘要

A data flow graph processing device that transforms a data flow graph including a loop structure into a pipeline operation capable of determining node execution order and judging whether or not executable, comprises: a delay node divider that divides a delay node included in t data flow graph into a value update node and a value output node; a dependency relation adder that adds dependency relations from the start node of the data flow graph to the value output node; and a hidden dependency relation adder that adds hidden dependency relations, indicating previous iteration and current iteration dependencies, from the value update node to the value output node.
