กระบวนการเพิ่มประสิทธิภาพวงจรดิจิทัลด้วยเทคนิคการสังเคราะห์ที่ระดับสูงสำหรับการปรับปรุงระบบตรวจจับเลนถนน

Abstract

In this work, road lane detection is proposed to reciprocate the requirements of Lane Keeping Assistant System (LKAS) and Lane Departure Warning System (LDWS), which are the position of lane line on image and the tolerance to the unexpected road lane, especially curve lane. The angle calculation is proposed to realize the curve's direction. The speed and memory usage of an algorithm are improved as well by adding the High Level Synthesis (HLS) optimization techniques. Array sizing, loop unrolling, loop pipelining, array partitioning and HLS interface management are respectively applied according to the limitation of resources and the speed of operation time using HLS development on Xilinx Zynq-7000 family (Zybo z7-10). From the experimental results, the proposed method reaches 6.66 times faster than the original at clock frequency 100 MHz.
