基于ARM自动指纹识别系统研究

ARM-based Automated Fingerprint Identification System Development

随着新型半导体指纹采集传感器件和DSP,CPLD技术的发展,自动指纹识别技术正向着小型化和嵌入式的方向发展;深入研究了ARM、CPLD、FPS200芯片及其外围器件结构特性,设计出了系统的硬件原理图并制作硬件电路板;设计了系统的USB通讯程序和上位机人机交互软件;最后进行了联机调试,得到了预期的实验结果。

With the acquisition of new semiconductor fingerprint sensors and DSP, CPLD technology, automatic fingerprint recognition technology is toward small and embedded in the direction of the development of in-depth study of the ARM, CPLD, FPS200 chip and device structure of the external design the system＇s hardware schematics amt PCB production hardware design of the system＇s USB PC communications procedures and interactive software; Finally, the on-line debugging, by the expected results.
