Abstract: Based on Zynq chip,the whole system is implemented with hardware and software co-design method.ARM+FPGA is used as internal architecture of the Zynq,so it has both of their advantages,which are flexibility of ARM and parallel processing capability of FPGA.The two advantages are fully used in this system.Image acquisition is implemented by ARM software design.Corner and edge detection is implemented by FPGA hardware design.The ARM processor and FPGA did the data interaction through bus AX14.This system has 3 main functions,which are image acquisition,image feature extraction and image display.The results show that this system implemented by Zynq,which used hardware acceleration algorithm,is 6 to 8 times faster than that of implemented only by ARM processor.

Key words: Zynq,FPGA,Feature extraction,Hardware and software co-design
