摘要
提出了一种以定点DSP芯片TMS320VC5410及FPS200指纹采集传感器为核心的自动指纹识别模块,并对指纹识别算法采用DSP专用汇编指令集与C语言混合编程的方法,以此实现了一个高效低功耗的嵌入式系统。文中介绍了其组成原理、硬件结构设计、系统功能设计、图像采集电路的实现,以及指纹识别算法的处理流程和实现方法。通过试验,该模块的采集效率高、识别速度快且准确可靠,总体性能是令人满意的。
An automatic fingerprint identification module based on the fixed DSP chip TMS320VC5410 and the fingerprint sensor FPS200 is presented. The program of fingerprint identification algorithm mixes the assemble language and C, which implements a high effective and low cost embedded system. The software and hardware design and implementation of this system are introduced later. In experiments, the module is fast speed and accurate, and takes a very good performance.
