摘要
提出了一种指纹识别系统的低功耗设计方法,采用基于双控制核心的系统构架,将指纹识别功能和外设控制功能独立分开的设计,以ARM核心的ML67Q5250实现指纹的采集、处理、识别和匹配,以16位的超低功耗单片机MSP430F149控制外围设备实现指纹识别系统的具体应用,解决了指纹识别系统的高效率和低功耗的问题。
A kind of duo-control-core system is introduced to reduce the power consumption of fingerprint identification system. One control core, ML67Q5250, realizes the functions of collecting, processing, recognizing and matching of the fingerprint image, while the other control core, MSP430F149, realizes the function of controlling all the peripheral units. Consequently, the contradiction of high efficiency and low power consumption can be solved perfectly.
