Firstly, after the static and dynamic resource consumption of the system evaluated a hardware architecture based on Field Programmable Gate Array(FPGA) and Acorn RISC Machine(ARM) is given. In this architecture, FPGA is used as core processing unit, and ARM is used as control unit. Then, the software design of the image processing system is introduced, and a communication protocol frame structure for system debugging is proposed. Finally, the practical experiments demonstrate the good real-time and reliability performance of proposed system.
