本系统计划采用xilinx公司Spartan 3E系列FPGA作为核心控制芯片，通过SPI接口使用FPC1011C指纹传感器实现对指纹图象的采集，利用FPGA芯片资源对指纹图像进行中心点求取、图像修剪、可视化扇形、归一化、Gabor滤波、特征编码等处理，之后执行指纹模板建档或者指纹匹配。使用MicroBlaze软核实现系统的管理，在数据处理方面尽可能多的使用纯硬件实现，保证功能实现的准确性和速度。该识别系统可用于门禁、考勤、证件管理等很多方面，具有很广泛的应用前景。

The Xilinx FPGA of family Spartan-3E will be used as the central control device in this Fingerprint Identification System, which can collect the fingerprint image by a fingerprint sensor named FPC1011C via the SPI interface, then figure out the central point of the fingerprint, thirdly shave the picture, fourthly transform it into a visual sector, then deal with it for generalization , Gabor filter and characteristic code, finally establish the fingerprint model file or execute operation of fingerprint matching. In this system, MicroBlaze Core is used for system management, and the module for data processing will be realized with hardware as much as possible in order to ensure the precision of function of the system and improve the speed of processing. The application of this system is versatile such as door guard, work attendance checking, certificate supervision and so on.
