Design of Image Acquisition and Storage System Based on ARM+FPGA

针对传统图像在采集传输速度慢,图像处理功耗高的问题,文中提出一种基于ARM+FPGA的图像采集与存储系统,将采集的图像数据输入到FPGA中,利用FPGA并行数据处理方式,提高其传输速度,再利用AXI总线与ARM进行数据间的高速交互,ARM对数据进行处理,FPGA进行加速。对数据的采集与处理分布进行,有效提升转换速率,降低系统功耗,最后将图像存储到SD卡中,验证了ARM+FPGA平台在图像采集、处理与存储的有效性和准确性。

Aiming at the problems of slow acquisition and transmission speed of traditional images and high power consump-tion of image processing,an image acquisition and storage system based on ARM+FPGA is proposed in this paper.The collected image data is input into FPGA,and the FPGA parallel data processing method is used to improve its transmission speed.Then,the AXI bus is used to interact with ARM at high speed.ARM processes the data and FPGA accelerates it.The distribution of data acqui-sition and processing is carried out to effectively improve the conversion rate and reduce the power consumption of the system.Final-ly,the image is stored in the SD card,which verifies the effectiveness and accuracy of the ARM+FPGA platform in image acquisi-tion,processing and storage.
