FPGA-based Design And Gigabit Ethernet (GigE) Image Processing System

The image processing system has been widely used in many fields, such as industrial detection, medical detection, security monitoring, etc. And with the development of science and technology in today’s society, the application of image processing systems will be more widespread, but the requirements for the system will also be higher, such as lower power consumption, more powerful functions, faster speed, and so on. In order to adapt to the future development requirements of image processing systems, this paper has designed an image processing system based on FPGA and Gigabit Ethernet (GigE).In this paper, the image processing system, which uses FPGA of Stratix III family as the core processor and Gigabit Ethernet(GigE) as data transmission mode, includes image acquisition, image preprocessing, image data transmission and image display on the PC. The hardware and software design of system’s lower machine is the focus of this study. The hardware design includes system power module, FPGA peripheral circuit module, image acquisition interface module, GigE transmission module and storage module. The software design includes SOPC subsystem based on the Nios Ⅱ processor, image acquisition and storage module using Verilog language, GigE application program interface and image transmission program using C language.The system is high-speed circuit. In order to ensure system to run efficiently and steadily, the paper also studys the relevant knowledge of signal integrity, and uses the Cadence PCB SI software to simulate and analyze high-speed DDR3SDRAM memory device signals. The integration test results show that the system can efficiently complete the real-time image acquisition, transmission and other basic functions.
