Abstract:  From the angle of the chip, the characteristics of the current image processing system were deeply analyzed. Aiming at the shortcomings of the current embedded image processing system based on ARM that in the anterior the acquisition speed is slow and in the middle the image processing algorithms are not easy to be accelerated by FPGA hardware, in order to improve the speed of the anterior acquisition, also in order to facilitate various image processing algorithms to be accelerated by FPGA hardware in the middle and the design of the transmission and display in the posterior, Zynq chip whose internal integrated ARM and FPGA architecture was selected, a image processing system platform prototype was designed by software and hardware co-design method, and the performance of the system platform was analyzed. Test results show that, the anterior acquisition speed of the system platform compared with the use of pure ARM chip solution is improved by 234 times, the system platform also provides extensible FPGA hardware accelerated channel for the middle image processing algorithms, and also provides good support for the posterior results show.
