Finger print integration with non-application processor functions for power savings in an electronic device

A system includes a fingerprint sensor, an application processor, and an auxiliary processor. The application processor is operable to arm the fingerprint sensor prior to the application processor entering a low power or sleep mode. The auxiliary processor is to receive a state output from the fingerprint sensor. The state output is to cause activation of one or more functions of the auxiliary processor upon fingerprint authentication while leaving the application processor in the low power or sleep mode. 种系统包括指纹传感器、应用处理器和辅助处理器。该应用处理器能够操作以在该应用处理器进入低功率或睡眠模式之前装载该指纹传感器。该辅助处理器用于从该指纹传感器接收状态输出。该状态输出用于在使得该应用处理器处于所述低功率或睡眠模式中的同时在指纹认证时使得该辅助处理器的个或多个功能被激活。
