本文详细介绍了基于FPGA 的数字图像采集卡的设计，选用FPGA 和DSP 作为数字信号处理器；然后从单片容量，时钟,体积，控制复杂度几方面综合考虑，选用SDRAM 作为外围存储器；最后给出了系统的整体设计方案。数字图像采集卡的硬件设计主要分为输入输出电路设计、FPGA 外围电路设计和DSP 外围电路设计，分别给出了各部分电路的具体连接。关键字: FPGA；图像采集卡；DSP；电路设计Design and Development of Digital Image Acquisition Card based on FPGA YU Qin (China University of Petroleum, Shandong Dongying 257055) Abstract: It designs an auto-adaptive high resolution image process card in this paper. The basic form of an image acquisition system is digital signal processor, A/D and D/A converter, and memory. The system scheme for video image process card is put forward. The hardware design of image acquisition card includes input and output circuit design, FPGA circuit design and DSP circuit design. The main chips that used in this system is introduced first, and then we focuses on the connection of the circuit.Keywords: FPGA; Image Acquisition Card; DSP; Circuit Design
