Article Preview

One kind of ARM and FPGA integrated design ideas have been proposed in this paper. The cost of ARM and FPGA integrated design is not large, but it can be powerful and expand the scope of application of ARM and FPGA. The system can be divided into two parts: image acquisition and image processing (image compression and storage). The part of image acquisition is composed by the FPGA, and the part of image processing is by the ARM. The system uses high-speed SRAM switching mode “Ping-pong operation” can help to improve image acquisition speed on the part of image acquisition. In addition, the paper describes the method of image compression and image storage, JPEG2000 coding standard is used in image compression, and SQLite embedded database is used in image storage. The operation of the whole system can be stable and reliable through integrated debugging. The results show that the system can achieve the requirements of industrial site with required high acquisition of speed. Because the use of the “Ping-pong operation” in the system, the acquisition speed can be improved significantly and the effect can be reached in a high speed standard.
