High-level synthesis (HLS) is the technique that automatically convert the software to the hardware. However, hardware is not produced with excellent performance and circuit scale if software is not described in consideration of the hardware. In this paper, we create HLS oriented template matching function that generates optimal hardware. In the experiment, we perform HLS pure software program and the newly created program, and compare those circuit scale and processing speed. Further, we
