摘　　要：提出了一种基于FPGA的嵌入式指纹实时采集解决方案,用Verilog语言重点设计了SCCB、OV7620和VGA等接口控制器,借助于EDK(Embeded Development Kit)软件,实现了硬件逻辑模块的组装和软件程序的编写,构成完整的嵌入式系统。经验证系统所采集的指纹图像完全能满足系统需求。This paper introduces an embedded solving plan of fingerprint image real-time capture based on FPGA. The control interfaces of SCCB, OV7620 and VGA are especially designed with Verilog. Assembly of hard logic module and compile of software is realized in EDK, formed an integrated Embedded System. The experiment proves fingerprint image captured by this system absolutely fulfilled the requirement of the system.
