一种新型SOPC自动指纹识别系统设计，：本文设计了一种基于SOPC的新型结构的自动指纹识别系统。通过对指纹处理整体流程的选择和优化，把耗时较多的指纹预处理部分整体硬件化，耗时较少的匹配部分软件化，使得系统处理速度有了显著提高，1.5s内可以完成一幅指纹图像的预处理，3s内可以完成一幅指纹图像的比对。本设计使用Quartus II软件完成了系统模块设计及仿真，使用NiosⅡ IDE软件完成了软件代码的实现，并在以Altera 公司的Cyclone II FPGA芯片为核心的DE2开发板上实现了整个系统。-The design of a new SOPC Automated Fingerprint Identification System: Design of an Automated Fingerprint Identification System Based on SOPC new structure. 1.5s within can be completed by the selection and optimization of the overall process of fingerprint processing and more time-consuming fingerprint preprocessing part of the overall hardware, less time-consuming matching of some of the software, making the system processing speed has improved significantly pieces of fingerprint image preprocessing, 3s can complete a fingerprint image. This design the system module design and simulation using Quartus II software, Nios Ⅱ IDE software to complete the implementation of the software code, and the DE2 development board with Altera Corporation' s Cyclone II FPGA chip as the core of the whole system.
