摘　　要：随着指纹识别技术日渐成熟及指纹采集设备价格的大幅度下降,普及指纹身份验证系统的时机越来越成熟。在目前的指纹自动识别技术的基础上对指纹处理算法做了较大的改进,使算法非常实用可靠。在此技术前提下介绍用MCS-51和Motorola DSP56311构建主从式指纹自动识别系统的技术要点。With development of fingerprint auto-identifing technology and the rapidly decreasing price of fingerprint collecting device, the condition for fingerprint identifying system to be popularized is expected to mature. The current arithmetic of fingerprint identifying is improved and is very practical and credible. The key technology in the fingerprint indentifying system which are composed of MCS-51 and Motorola DSP56311 is described.
