Research Abstract	In embedded systems, the need for rapid low-cost development has been increasing recently. Reuse of design assets is thus an important technique in embedded systems. However, reusability is generally low in software that has been specialized for a particular execution environment. This study proposes a software acceleration technique that is able to maintain software reusability. The proposed technique accelerates the software processing speed by employing dynamic data path generation from the software execution code. In the results of our work, the execution time of most internal loops was decreased by an average of 38.0% and a maximum of 42.3%. This result indicates the possibility that our proposed acceleration technique may promote software reusability while increasing software processing speed.
