Design of low power consumption fingerprint lock based on DSP
The paper focuses on the design method based on the low power consumption of the embedded DSP fingerprint lock. Considering the features of the off-line fingerprint lock,the paper discusses the realization of the overall low power consumption of the system in the hardware design,adopts the non-traditional saving power design of the collector head in the photo sensor and combines the optimal designs of the hardware and the software in the core processor and the bottom controller. The paper realizes the low power consumption of the off-line fingerprint lock by choosing the cost-effective and low power consumption components,optimizing the software design and reducing the overall power consumption of the system.
